My hearing aids maximum capacity is 7800 HZ. TLS, could you please further explain "turnover frequency on my audiogram"? I do not believe I am not asking my hearing aid person the proper question.
Noise damage to hearing like you describe, is called sensineural hearing loss. The is a fairly abrupt region in the frequency spectrum where the hearing declines.
In the above audiogram the turnover frequency is 2250 Hz. This patient would be mildly deaf and still have quite good speech discrimination.
This patient's turnover frequency is 1500 Hz. This patient would have quite symptomatic hearing loss and would have difficulty understanding conversational speech. Hearing aids are likely to be helpful. This is where patient's most often present for evaluation.
This patient's turnover frequency is 500 Hz. This patient would be quite profoundly deaf, and speech discrimination impossible without some degree of lip reading. Amplification will help, but be of limited benefit.
The above audiograms are what is seen in damage to the cochlear apparatus or auditory nerve, most commonly the former.
On the other hand conductive hearing loss looks like this.
This occurs if the middle ear fills up with fluid (middle ear effusion) or if the bony ossicles fuse (otosclerosis) or are damaged by middle ear infections.
I hope this explains what I am talking about.
I have to say the professionals evaluating and assisting you have failed to educate you about your condition. This is basic information that should have been explained to you by your professionals. I should not be having to explain this to you on an audio forum. However I'm glad to help. I hope it gives you better insight into your condition.
