The Effect Of High Frequency Amplification On Subjective And Objective Benefit With Digital Hearing Instruments, Erica Lynn Fleck

LSU Master's Theses

The purpose of the present study was to determine whether amplifying beyond 3 kHz was beneficial to the user, whether the benefit was dependent on degree of loss, and whether subjective data reflected the benefit. Seventeen hearing impaired subjects were binaurally fitted with digital hearing instruments. Qualified subjects were divided into two groups, A and B. Group A had a pure tone average (3,4, and 6 kHz), of 55 dBHL or better. Group B had a pure tone average (3,4, and 6 kHz) greater than 55 dBHL but not exceeding 75 dBHL. Each subject was fit with two conditions (upward …
