I own Smith's book. I think it has some good info. Again, I misunderstood what I read. It seems to be the opposite that if you’re past 50, you can no longer hear well enough to really care about your sound quality. You can!

If you really want to be depressed, give the new thing "all the kids are doing" these days a try: "mosquito ring tones" (shakes fist, you darn kids...!). So, anyway, apparently the trick is to put a high-frequency ring tone on your phone that adults can't hear. Phone calls in class, no problem, teacher can't hear it. Supposed to be doing homework...you get the idea. As it says on one of the websites: What is the Mosquito Ringtone? The short version, A tone outside the audible range of hearing for most people over the age of 30. This means that you can get phone calls and receive text messages in class or school without teachers hearing it. For more in-depth information on how the mosquito ringtone works, please see the Mosquito RingTone FAQ. For information on how to get the ringtone on to your phone, see our Mosquito Ringtone how-to Guide. And so, you can check them out, for example, here, where there are samples that you can listen to. There are tones from 8 to 22khz, together with supposed age ranges that are unable to hear each frequency. At the ripe old age of 37, I officially couldn't hear anything above 12khz -- which according to their estimates, puts my ears at age 50+. Oh joy. Interesting, but not happy-making. Interested to see what others think. All that said, I really don't feel like I'm missing anything, even 12khz is not something I'm really ever interested in listening to again, not exactly pleasant.... |
That's pretty cool. Hadn't considered how much a function of volume it is, with more volume, I can hear the tones up to 17.4khz (which would make my ears younger than I). As four the loudness/frequency test, came out almost flat, with significant drops in sensitivity starting below 250hz and above 8khz. How about that. |
