Hearing Tests


I am wondering about the accuracy of online hearing tests. As we get older our ability to hear high frequency sounds is supposed to gradually decline. I imagine this is true for the vast majority of people. But my mother was nearly 100 when she passed away and her hearing was so acute that the nurses in the hospital were dumbfounded when my mother recounted the content of a conversation nearly-whispered between two nurses in the next room.

Since I am well into my 60s now I was concerned whether I have lost a significant amount of my hearing capacity. It seems to me that I can still hear the finest nuances from my system but you don't know what you are not hearing. But since I have always protected my ears from loud sounds of any kind I thought that maybe I could dodge the bullet. So, I took 3 online hearing tests and they came out just about smack on with the same results, which I was happy to see. The results said I have excellent hearing.

Here are the links to the 3 tests I used to test my hearing:

Of course, online tests are not the same as having your hearing tested in a doctor's office. But do they have validity? And, if so, to what extent are they valid? I wish I could find the recent Audiogon thread where someone stated with authority that no one over a certain age (I can't remember the age mentioned) can actually hear above a frequency of 10,000 or 12,000 Hertz (I cannot remember which frequency was quoted).

Do you have any experience with hearing change as we get older and with the validity of hearing tests?

Audiosampling,

I scored great up to 13Khz and then all bets were off. I could, however, detect down to 1db difference with 100% accuracy and down to a 10c pitch difference with 100% accuracy as well. I guess somethings work and make up for others that don't.

Could it be that a change in timbre or tone can lead one to figure out the rest aided with memory? Or is it that what we think are frequencies from the tweeter are just the higher limits of the midrange driver?

They say that most of what we hear is in the midrange.
Thanks for the site. If was fun to have as blind a test as possible without going to a doc.

All the best,

I apologize for saying that the audiocheck site had limited FR. I didn't see that the extended ranges were on other pages.

Still, knowing the frequency and level when being a subject is a bias. Better to have someone else administer the test to you.
I can't speak to the online tests, but to answer part of your question, some people's hearing can get more sensitive to high frequency at a certain age.
Due to high frequencies starting to bother me, I saw an ENT and an Audiologist recently and I can still hear 19 kHZ tone...no hearing loss at age 55. My mother is 85 and her hearing has become more sensitive over the last few years. If you're concerned, you should get a proper hearing test.
Lowrider57,
This is very interesting information. It goes against the accepted wisdom that we inevitably lose hearing as we get older.
I think Lowrider57 may be onto something. My mothers hearing got more sensitive to higher frequencies although her hearing acuity, overall, got worse.

There are very few bright recordings that tend to annoy. It's usually a bad recording (that old 'digital' sound) though I shouldn't be hearing them as of now, should I? Maybe it's part hereditary.
It's more akin to noise than music.
Could it be I'm tiring of digital music? :-)

All the best,
