Lightbulbs asked:

"why don't audiologists have machinery to test up to 16 khz"

Some do; some don't. The audiologist I work with has "high frequency audiometry" equipment that tests up to 20K, but she uses that equipment only when testing tinnitus patients.

Most audiologists do not test much beyond the frequencies required for effective communication.

So this morning I ran the above post by Dr. Lyn Rushton, the incredible audiologist I mentioned above, and she added a few things ...

In addition to using high frequency audiometry for tinnitus testing, she also uses it to detect the earliest signs of ototoxicity in cancer patients who are on platinum-based chemotherapeutic agents.

She also reminded me that as far as communication goes, the following sounds lie around 500Hz: vowels, m, n, b, d, g

and the following sounds lie closer to 4K: s, sh, th, f

In other words, regarding communication there is no real need to test above 6-8K. Indeed, while some musicians and bird-watchers might be interested in amplifying sounds around 8K, most folks find amplification in that range to be screechy, tinny, or sharp.

Thus, back to your original question about testing at 16K - for the vast majority of patients who cross the threshold of an audiologist's office, there is simply no need!

Hope this helps.
