Hearing Aids and Further Hearing Loss? Part III

Do Hearing Aids Cause Further Hearing Loss?24a

The past couple of weeks the topic of whether hearing aids cause further hearing loss has been presented.  Last week’s post on this topic reviewed some of the case studies that have been published on this subject.  Although of significant interest, most are single case studies and often fall into the category of being anecdotal reports because the conditions leading to the event often are sketchy.  The underlying issue, as discussed previously, involves the relationship of TTS (Temporary Threshold Shift) to PTT (Permanent Threshold Shift).  This post reviews some of the results from controlled studies involving larger groups of subjects.  Subsequent posts will discuss the results.
