Are you also under the impression that when people (or
manufacturers) demo their equipment, they maintain sound pressure levels
between 90-100 Dba. In general this is done in rooms being too small, and
therefore the room will heavily interact with the sound heard in that room.
Often, when you ask to lower the volume, the actual result is better, and –most
likely- provides you with the information you were looking for. So, my question here is, do you also prefer
to listen in the 90-100 dba range? Or do you –like myself- like to listen in
the 70-90 dba sound pressure range? Of course, I’m referring to sound pressure
levels at the listening position, which –in my case- is about 4 meter away from
the speaker.
I think we should draw a distinction between what sounds loud, and sound pressure level, as they are two different things. Also, the distortion as written about herein this thread (occurring in speakers as the volume is raised at and above 95db) is occurring in the *higher frequency band* (above 2K) as measured by sound stage. Those higher frequencies aren't necessarily the dominant factor when it comes to SPL.
In other words, I submit to the group that one CAN produce (hypothetical example) 100 db without much if any distortion, AND it may not sound (very) "loud". How so? Simple. Play music whose content is primarily lower frequencies, drums, organ, etc. If vocal and higher frequency sounds are absent, you'll have your high SPL, little if any distortion and it likely wouldn't be perceived as "loud" as if you had played a vocal track and then achieved the 100db on the basis of the vocals.
No, it doesn't have to be loud. I listen typically anywhere between 60 and 75 dBs, and it is plenty loud for me. Could I play it louder and as clean (i.e., without distortion) on my system? Sure, but I see little point to it. The fact is that the human ear is a very sensitive organ, and extended exposure to high dBs is likely to result in major damage. As a musician, I have always used hearing protection when gigging and rehearsing ... and, I'll tell you this ... my bandmates who failed to use hearing protection now are hard of hearing. OTOH, I can still enjoy listening at low levels on a great system without causing permanent damage to my ears.
I have heard the Tekton Double Impact (not the SE version) at a recent audio show. I really liked what I heard; certainly a great bargain at its price. I bet the SE version sounds even better. I don't recall what amplifier was being used. At 99 db/w, these speakers can be used with very low wattage amps, particularly if the speakers are played at reasonable levels. To me, it is more of a bragging rights kind of thing that a speaker can play at 115 db--I would not want to listen at that kind of level (like owning a road car that can go 220 mph).
While I have stated a preference for tube gear, particularly where one can get by with modest amounts of power, I certainly expect that good solid state gear can be quite satisfying. I have not had that much exposure to Pass amplifiers, but, the First Watt amps I mentioned that I really liked are designed by Nelson Pass. The First Watt gear is aimed at a particular niche market--high efficiency speakers that present an easy load to drive. I like your choice of the lower powered model from Pass' lineup. I once auditioned a 50 watt solid state amp and a much higher-powered model from the same manufacturer (both very similar in design) and preferred the lower power model; it might be use of fewer transistors operating in parallel that made the difference (I hear the same thing with using multiple tubes to achieve higher power output, the result is not good).
Most of the better brands of solid state gear deliver decent performance. There is a sameness to the sound of solid state, including Class D, that makes it actually hard to make a terrible choice. That is not the case with tube gear. There is much more variety in sound with tube gear and that is both good and bad--good if you carefully choose what works with your system and taste (or get lucky), more likely bad if you don't carefully audition and choose wisely. A lot of even "bad" (to me anyway) tube gear will still deliver the rich sound and enveloping soundstage that is the most obvious characteristics of tube gear, and one can easily, at first, miss problems in other areas of performance. It takes more experience finding the right tube gear choice.
I should also mention that, I also like the Ayre brand of solid state electronics. For Class D stuff, I have heard decent sound from Bel Canto amplifiers.
I do agree with you that -in general- very few speakers will comfortably go much higher than 95 dba, without running into higher distortion. The moment you can see the woofer "working hard" there is a very realistic chance that you are entering higher distortion levels as well. At 95 dba, almost all speakers will show this "working hard", they will have to move a certain volume of air to reach the higher sound pressure levels, so as woofers themselves have a certain mass, they will start to "overshoot (both positive and negative overshoots). This will create distortion. (easy to envision). Manufacturers will try solving this by selecting different materials, stronger magnets, tighter tolerances, adding more woofer units, or a combination go the above. In general this results in higher costs. As I like dynamics, and in general stay below 90 dba, my system is still quite within its "comfort zone". At least you don't see its 16 woofers working yet ;)
If you have not tested your speakers at those levels then I am afraid you cannot know through mathematically applying max rated amplifier power (watts) and multiplying that to your speaker sensitivity. Perhaps I was not clear - very few if any speakers can play that loud without excessive distortion.
I can show Soundstage plots where large Wilson and large Magico speakers (hardly low end) that are already distorting at a mere 95 dB SPL.
I trust you to continue stalking me. You could spice up your posts with a little humor. It wouldn’t kill you.
My senses are pretty good, and I do sense some sincerity and perhaps the offer of the proverbial carrot in your last post, hence the reason I shall respond. It is true that my sense of humor is "different" than most. To an extent, "warped" in fact. I'll consider your advice to spice up my posts, but in all likelihood my written responses would not deviate from my already established norm. I've posted this elsewhere on the forum, but perhaps it needs to be reiterated that "I’m proud to be in the minority".
You do realize that I’m very much aware that you’re "following me" throughout the forum from thread-to-thread and post-to-post. Splendid! You could learn something.
Uh, shadorne, trust me, high end speakers do not (rpt not) distort at moderate or higher than moderate levels. Where did you hear that fairy tale? 🧚🏻♀️ Even ordinary speakers, you know, ones that are not junk, don’t distort unless overdriven, which is not what I’m talking about. There is no physical reason why the system, any system, should become unlistenable at moderately high levels. Of course I completely understand that many people are accustomed to the distortion. It’s always been there.
This needs a new post as opposed to editing my previous post.....
At the moment I’m on my "set break" during my listening session of the incredible Leonard Cohen. Specifically, I’m listening to 7/9/85, Montreux Jazz Festival, Switzerland. Now for those familiar with his music, surely you’d agree that typically, a volume level of 85 db is plenty "realistic".
That said, there are times/occasions where I just get the right "vibe"....
If you want to toe tap, head bob and essentially get up and dance, I’d recommend two songs from this show: "there is a war" and "lover, lover, lover". They sound amazing in the mid 90s (db). Trust me! :)
EDIT:
So the point I'm attempting to make here is that often it's not simply the genre or artist, but the specific song and ones own state-of-mind at the time you're listening that governs the volume control.
Keep cranking it until you get the meter reflecting sustained levels at 115 db SPL. If it sounds clear and clean and undistorted (but obviously very loud) then you can be assured the speakers are fully capable.
I’ll pass on that :)
What I stated is that on the basis of my speakers rated (manufacturer specs) sensitivity and power handling capability, they can produce over 115 db. Besides, even if my speakers cannot attain that decibel level, I would still consider them "fully capable" because that level is a bit unrealistic.
Additionally, I live in a coop. I do make an attempt to show some respect towards others. My neighbors already endure the fact that most of time (I listen 3 hours per day) I listen to Grateful Dead, which sounds realistic from a live concert perspective topping off around 95 db, often even lower. On lessor occasions I’ll listen to Nirvana, AC/DC, Deep Purple and a hand full of other select choices that "warrant" playing at louder (compared to many other bands) levels. Even in those cases I’ll top out in the low 100s.
EDIT:
And if I'm not mistaken, 115 db is "dangerous to the health of ones ears" if sustained for an undo length of time.
Nothing mysterious - all speakers distort terribly and very quickly. This is why pro monitoring gear used as main monitors in high end studios is so very expensive. This is why PA speakers in your local bar go loud but sound awful. Getting loud clean distortion free sound is a significant engineering hurdle and a costly manufacturing effort too. The diminishing returns are incredible - each extra 3 db in distortion free loudness capability pretty much DOUBLES your costs.
Since you have a dB SPL meter it is a very simple matter to check your own speakers.
Keep cranking it until you get the meter reflecting sustained levels at 115 db SPL. If it sounds clear and clean and undistorted (but obviously very loud) then you can be assured the speakers are fully capable.
A great test track is the Sheffield labs drum track CD with track 1 - this is quite a good workout for a speaker as it is highly dynamic and also broad in frequency response (bass as well as mid range and tweeter are all heavily used).
I would suggest that you use a simple formula to estimate if your speakers are producing a combined at 115 db SPL at 1 meter. At your listening position the SPL meter should read 112 db SPL at 2 meters from speakers and 109 db SPL at 4 meters back. Since sound is dynamic you can expect the meter to only stay at such a sustained high level during drum rolls for a couple of seconds.
Of course you should never listen at these levels on a continous basis.
I’d opine the whole phenomenon of distortion increasing with volume is more mysterious than anyone gives it credit for. There is no reason why distortion should increase since for all intent and purposes the SNR remains the same as the volume is turned up. Obviously driving the system behind it’s capability, for example clipping, is not what I’m referring to. Amplifiers and speakers are linear devices so there is no reason why distortion should rise with volume. Yet all systems exhibit this phenomenon. That’s why people complain of fatigue and harshness at higher than moderate volume. But it’s not the speakers and it’s not the electronics. It’s something else. Something very mysterious. 😳
Since our ears and brain interprete distortion as loudness most audiophiles think they have speakers that play extremely loud however a dB meter will confirm to them that what they think is loud is actually just huge amounts of distortion giving the appearance of loudness.
Hi @shadorne
I appreciate your response to my question earlier in the thread. I’ll grant you that, unfortunately, sound stage does not seem to test above 95db. In the case of my particular speakers (Golden Ear T Ref), I consider the fact that they are a few db’s off "perfect" linearity, and even then over a small range of high frequency, essentially linear where the ability to play loud without distortion is concerned. On the basis of their sensitivity and power handling capability, they can produce over 115 db. And, I have reason to believe they could do so without damaging themselves in the process.
I certainly do agree with you that distortion increases as volume increases. But I think I’ve attended enough live events to know that - at least in my particular case - my system is more than capable of producing realistic rock concert level sound pressure, with (seemingly) no more distortion than the live event itself would produce. So, the fact that distortion increases with volume (generally speaking) is what it is, and IMO is largely irrelevant to the enjoyment of the listening session (unless the distortion is such that it becomes obvious).
To your point I’ve quoted above, I’ll disagree. Distortion doesn’t necessarily give the appearance of loudness. Distortion sounds "wrong" whereas loud and relatively undistorted music can sound authentic (and "right"), like a live event.
A db meter is used to confirm sound pressure level, not the "quality" of the sound. The db meter doesn’t care if the sound is distorted or not. Sound pressure is just that; sound pressure. So, whether or not the SPL is reading distortion or genuinely loud and un-distorted sound shouldn’t matter (from the perspective of the listener perceiving the sound as loud or soft).
EDIT:
Besides the fact that I do have an SPL meter, there are numerous charts available that provide insight as to sound pressure level. Here is one of many: https://ehs.yale.edu/sites/default/files/files/decibel-level-chart.pdf It is based on my SPL meter and general understanding that if a subway train at 200 feet is 95 db, my apartment at times can sound as though the train is 50 feet away :)
@larryi Thank you very much for your response. It’s very helpful.
I’m at a fork in the road with amplification (tubed or solid state) and have essentially chosen the solid state path. I’m also preparing to evaluate a few (new to me) solid state amps. My current amp is the Pass XA-30.8 The Pass performs very well at low listening levels, for my needs and preferences. Speakers are the Tekton SEs (99dB 2.83V@1m).
I hope your findings (copied below) do not bear out, as I am hopeful that my low powered options will perform well at low listening volumes (though I understand and generally agree with what you are saying below, especially at lower price points).
But, when even decent sounding solid state amps are played at the lower levels I prefer, they sound a bit lifeless, and I tend to lose interest.
If you have additional thoughts and advice regarding this, please share (PM me if it makes more sense to reach out that way). Thanks!
audiophiles think they have speakers that play extremely loud however a dB meter will confirm to them that what they think is loud is actually just huge amounts of distortion giving the appearance of loudness
You make a great argument for horn design many sound amazing at low levels but have extremely low distortion as SPL increases
The mathematics you use are correct. However speakers do not behave linearly after a certain point. Worse speakers distort terribly. That point is surprisingly low. Soundstage do NOT test speakers above 95 dB SPL as a level above that will damage most speakers!! (Soundstage conclusions and not my opinion).
Drivers have a limited excursion where they are fairly linear (Xmax). Driver voice coils get extremely hot and that causes significant compression (non linearity). There are a huge amount of challenges for high fidelity (no added distortion) at rock concert levels.
My speakers play at 115 dB SPL linearly even at a continuous level with similar low distortion to playing at modest 85 dB levels. This is extremely rare in a speaker and requires large woofers, large drive motors on the drivers (huuuge magnets), short voice coils in a large gap (to preserve linearity),large diameter voice coils (for better cooling), extremely tight tolerances (better cooling) and lots of clean power - in short a huge amount of engineering is required to achieve this over a speaker that is designed to only play up to 95 dB SPL before starting to distort heavily (the majority of designs). To achieve this performance requires specific engineering that you won’t find in 99.9% of home audio.
Since our ears and brain interprete distortion as loudness most audiophiles think they have speakers that play extremely loud however a dB meter will confirm to them that what they think is loud is actually just huge amounts of distortion giving the appearance of loudness.
The amps I have liked the most are tube amps. I own a custom-built push-pull 45 amp, the Audio Note (uk) Kageki (parallel 2a3 SET) and a custom-built push-pull 349 amp. The Kageki, rated at 6.5 watts/channel, is the most powerful of the trio. But, I had in my system a solid state First Watt J2 for about two weeks (borrowed from a friend). The J2 sounded very good--it was vivid and engaging and only a touch hard on the initial attack of notes. I could easily live with the J2. That same friend built for himself a low-powered SIT amp based on schematics made available by First Watt. I think that this is also an excellent low-powered solid state amp.
In the past, the common complaint raised against solid state is that the sound tended to be harsh and "grainy." I don't think that is the case these days. Most solid state amps are smooth sounding and are not at all unpleasantly harsh or shrill. To me, the complaint about harsh and shrill can more often be leveled against high-powered tube gear than solid state gear. But, when even decent sounding solid state amps are played at the lower levels I prefer, they sound a bit lifeless, and I tend to lose interest. A friend of mine, who also loves low-powered tube gear, and who has heard much more stuff than I have (he goes to the Munich show), says that the Bridge Audio Laboratories (BAlabo) high-powered amps sound good. I have not heard these amps, and in any case, I could never afford to buy amps that cost six figures.
I am with the crowd that thinks the ability to sound good at lower volume is a high priority. Yes, the ability to play at high volume is a criterion of performance, but, the ability to sound dynamic, full and exciting at low volume is more important to me. I know one can show that classical music has an enormous dynamic range such that the peaks can be well over 100 db. But, recordings don't come close to delivering the full dynamic range; if you set the peaks at 100 db, the quiet passages are unrealistically loud and inappropriate. I don't ever play such music at "realistic" peak volume. For amplified music, I don't ever want to attempt to duplicate a live performance; frankly, if my system only sounded as good as perfectly reproducing such performances, I would dump it.
The very best systems at sounding good at low volume levels also tend to ones that are highly efficient and easy to drive. That allows the use of low-powered amps. That is a really big deal to me because ALL of the amps I really like happen to be quite low in output (the most powerful is a custom-built OTL amp at 30 watts). I haven't heard most of the high-powered candidates out there, but, I've heard a few and they have the same problem--they sound dull and lifeless and un-engaging, particularly if you don't crank up the volume.
I understand that doubling the power results in a 3db increase. Speaker manufactures typically include a sensitivity measurement *and* a recommended amplification power measurement.
Can one draw an inference as to the maximum spl capabilities of the speaker based on its sensitivity and recommended amplification level? I believe, "yes".
For example, if a speaker is rated at 93db sensitivity, and the recommended amplification is 20-200 watts, then could one infer that the speaker can produce (approximately) 115db "comfortably"?
Many people are a tone of deafness that the reason they listen loudly if these people consult an orl surprise they don t hear middle and high frequency but especially grave
First of all, thanks all of you for your input. I do agree
that it is more about dynamics rather that just loudness. Any continued SPL
above 85 dba will result in hearing damage, so needless to say this is not
recommended. My hearing –after 40 years running around on electricity power
plants- is not very good anymore, Nevertheless, I’m certainly able to enjoy the
music, and I love the dynamics. Unfortunately, not many systems are able to
present the full dynamic range available. Most of the systems will run into distortion
when playing 90-95 dba SPL at listening position. Don’t be fooled, 95 dba is loud! Now,
considering a background noise level of let’s say 40 dba, and a dynamic range
of 50 db on a very good CD, your system must be able to produce undistorted SPL
of 90 dba. That’s it. You may wish to
have a bit headroom, but if your system plays SPL peaks up to 95 dba
undistorted, you’re good. Believe me,
not too many systems can. Other than
that, I play music at a level which I believe would be natural. So if a singer
would be standing in between the speakers, how loud could she/he possibly sing
without amplification, that’s the norm for me. Of course, occasionally I do
play louder, depending on the music. But hardly ever do I exceed the 90-95 dba
peak SPL. (and yes, I measure with an Extech SPL meter, it does make a difference)
I have tried numerous phone apps with multiple phones and they all read about 6 to 8 db lower than my Extech meter. I’ve only encountered one app that allows a C-weighted measurement, but it doesn’t record peaks like the Extech. If you blow into the mic of a real meter you can easily register over 100db. Try doing it with a phone mic and you’ll max out around 90db.
What we are missing once again is individual differences. We all hear differently. Women have more sensitive hearing, so Elizabeth may hear at 70 dbs what it takes some of us 90 dbs to hear. And women are not the only ones who may have better hearing.
I don’t like loud music. Didn’t when I was a kid, still don’t. As I have moved up the audio ladder my system has become more transparent and more natural sounding without having to increase the volume.
If you’re doing a lot of listening at 80 - 100 dbs you’re damaging your ears. Try turning it down for a little while. You may find your ears adjust.
70dB isn’t realistic. Kind of the level you would listen to the radio. If it doesn’t sound good any louder then there is something badly wrong with the setup.

This information can be helpful with estimating noise exposure and in identifying potential noise ’hot spots’. However, as shown, many of the instruments can exhibit a range of noise levels depending on how loudly they are played, for how long and under what circumstances (eg repertoire, venue, number of instruments concerned). Do not only use this information for a risk assessment but look at Sound Advice Note 3 ’Noise risk assessment and planning’and the relevant sector guide(s).
I listen at 50 to 60dB measured at listening chair. 70dB is pretty loud and I only rarely play music that loud, and 80dB peaks is as loud as I ever play music at home.(mainly opera climaxes.)
Are you using a real meter or one of those gimmicky phone apps? Is it set to fast C-weighting or A-weighting? Is your meter placed near your head?
Just put on "The Dave Brubeck Quartet in Europe," and Brubeck's big piano chords are peaking at 80-83 dB, and the applause at the end of each track is irritatingly loud at 85 db. It seems I need the volume up a bit to hear the bass, although that might be a deficiency of my system or (rather small 12.5' x 15') listening room.
I like to listen at the level I imagine the music would be played at if it were a live performance. I’m listening to John Fahey play acoustic guitar right now (with a pickup and amp, it sounds like, on his record of hymns, "Yes! Jesus Loves Me"), and after reading this got out my SPL meter and read about 80 dB on the loud parts.
I like orchestral music to be loud in the loud when it should be, of course. Of course there’s a lot of dynamic range in orchestral music. I wonder what concert hall SPLs are like.
A lot of the 50s and 60s-era acoustic jazz I like doesn’t need to be very loud to be enjoyable because it’s not too difficult to distinguish among four or five instruments.
Now I’m curious and will test myself and the music to see what works.
Personally when you start going over 90db not only are you abusing your hearing But permanent hearing loss + tinnitus. Also room reflections, your room and Natural flowing music will be an after thought ,unless you Have room correction of some type.
@gdhal - I agree that each recording seems to have a level, given room, system and recording, where everything comes together. I think that sometimes, "turning it up" is meant to get more immediacy, impact and get the system out of the way, and if everything (including the recording) isn’t up to snuff, it’s just playing louder at you, but doesn’t sound more real. So I get @geoffkait ’s point, in that some recordings are compressed where there is no real dynamic range- a/k/a loudness wars.
I went to hear Crimson several months ago in a good hall here in Austin. The next morning, I played some material from the 2016 Live in Toronto LPs- there was just no way I could reproduce the scale of that recording, or the level of bass, in my room (which is fairly large by normal residential standards) at anywhere near what I heard live. Nonetheless,the recording and system acquitted themselves pretty well in that half-assed live v. recorded comparison. I’ve aimed to get the resolving power of my system to a point where it doesn’t have to be super loud to be fully engaging and I do listen to a lot of very hard rock (mostly early stuff, before the term "proto-metal" was invented). It is a shame that some of the records I like from that era, e.g. the first two Zep albums are not very good recordings. But, there are some that are- try Brian Davison’s Every Which Way (U.S. Mercury) circa 1970 or 71. You can turn it up and enjoy it like you would a well recorded jazz record- sounds like early Traffic. Some of the better known heavy rock records, like the first Sabbath album on Vertigo Swirl (UK) sound very good, even though they are primitive. I find that I have to wear ear protection at almost all live rock events. They are just too loud and too often, overwhelm the room.
Also for less $$$ than you think you can get some nice tools to run on your phone or iPad, I use Studio Six Digital Audiotools RTA and a nice calibrated mic, unless I am lazy then I use the iPad microphone which ain’t too bad at 1k
Several good comments above that deserve amplification. I dont know what the SPLs are at my chair but i do know that:
1. the ear has a reduced sensitivity to extremes at low levels, so too low is not ideal 2. Noise will mask low level detail if the level is set too low. 3. Music also provides "feel" - does the kettle drum vibrate you? That's realistic.
Too loud certainly overloads both my comfort and my room( and generally not my amps, which i have the ability to measure, roughly). But too low obscures detail, even things like the texture of vocals. You may question if its a "good thing" but at moderately hgih levels i can often hear the artifacts of mixing. not so at lower levels.
And gladly, despite many decades, many concerts and tons of listening, i still hear very high frequencies in my lab - 15-20k. Down in audibility, yes, but I hear them. When i'd travel to our NY lab decades ago, my dog used to get annoyed when [name withheld) turned his oscillator up to a HF rather than off :-) Cant fool the dog.
As amazing and sensitive our sense of hearing is, it is insensitive to certain aspects of music at low volumes. 1. Dynamic range - when you listen at low volumes, loud passages aren't loud 2. Frequency extremes - our ears can't' hear deep bass frequencies or extended high frequencies at low volumes very well. 3. Harmonic overtones - harmonics, and the "feel" of the space of where the music was performed is lost at low volumes. This is why music is played loud at shows and for demo purposes. Although I agree that most tines the "demoer" overdoes it.
No and you can save a lot of money that way. Wear and tear on your ears as well if you keep it below 85 db or so most of the time. No good ears, no good sound....
It’s producing large quantities of good sound that is hardest and most expensive.
