Yikes, Phil! Explanation still needed........

[Guest guest]

I did go to the sites you gave me but Stevie's audiologist confused

me even more! He is saying that Stevie suffers from a hearing loss

to low noise levels. His chart, in front of me, shows the X mark

(left ear) steadily dropping downwards from the 2000 HZ level ending

at 35 at the 8000 HZ level. Wouldn't that mean that it's more

difficult to hear higher pitches or am I still confused?

Better way to explain it? X's are pretty much at the 20 line going

across to the 2000 Hz area, then it drops to 25 at the 4000 Hz and 35

at the 8000 Hz. Hope that explains it......

His right ear on the other hand reads at the 10 line mark across

until the 2000 Hz goes to 5 at the 4000 Hz and back down to 10 at

8000Hz.

Reminder: Left ear is the c-toma ear

usually happens is that people take a decibel figure and call it a

percent - which It isn't, of course. If an audiologist tells you that

your hearing loss is x%... well, they really shouldn't do that. This

article will explain why:

If there is a line with [ symbols, it refers to bone conduction

hearing , Low frequencies are on the left of the chart and high ones

on the right. Quiet is at the top of the chart and loudness at the

bottom. Most people with hearing loss have a chart that shows the

hearing level down slightly in the low frequencies, rising slightly

in the middle and then dipping sharply in the high frequencies. So a

hearing loss figure is usually given as the best decibel reading in

the middle frequencies. It's a little misleading because we are

always have a different level of deafness at different frequency

ranges. Taht makes it complicated and it's usually more meaningful

just to refer to deafness in terms of mild or moderate etc.

is severe and above that is profound. Here's a useful site that shows

you how to read an audiogram:
