Document Summary
Treatment for disorders of the hearing mechanism part ii. Problems associated with hl: sensorineural hl, reduced dynamic range. The difference (in db) between hearing threshold and the level at which sound becomes uncomfortable. Due to ohc damage: decreased frequency resolution. Affects speech understanding: decreased temporal resolution. The ability to detect gaps between stimuli. Difficulty understanding speech in background noise: conductive hl, reduced audibility (no damage to inner part of the ear, tend to do well with help. 1: make it easier to hear and understand speech. 4: reduce negative affects known to be related to hearing loss. Open fit behind the hear hearing aid. Receiver in the ear (rite) or receiver in the canal (ric) Invisible in the canal (iic: what is the best kind of hearing aid, role of an audiologist to help guide in making this decision, varies depending on:
