A Case for Mid-frequency Amplification?

Most individuals with hearing loss are affected mostly in the high frequencies. And, because consonants–those phonemes (distinctive speech sounds) that are believed to enable humans to differentiate one word from another–are high-frequency sounds, hearing aid fitting formulas universally call for high-frequency amplification. This continues to be a take-off of the old “audiogram fitting” approach (although with less…

Fitting Asymmetrical Hearing Loss

Asymmetrical hearing and unilateral hearing loss require solutions that do not seem to follow typical hearing aid fittings for bilateral sensorineural hearing loss.  Last week’s post on this subject showed the results of “loudness catch-up” of the poorer ear that indicated a pattern somewhat similar to the steep growth of loudness associated with classic sensorineural hearing…
