Hearing loss has a variety of negative impacts for it’s sufferer.
One common one is impairment that results in inability to distinguish high-frequency sounds. Traditionally, the greater the hearing loss, the more gain needs to be applied at that frequency. However, for some people, hearing sensitivity is so poor in the high frequencies that it is not possible to provide sufficient gain and achieve audibility. In many cases, the gain is limited by acoustic feedback or by discomfort, resulting from excessive loudness. Cochlear damage renders these sorts of frequency problems with hearing:
>>An inability to recognize certain speech sounds
>>Difficulty distinguishing high-pitched background sounds–like bird chirps and songs
