Comparison of Bone Anchored Hearing Aid with Test Band and Air Conduction Hearing Aid

Abstract

The aim of the present study was to compare the performance between the aided conditions with bilateral fitting of Bone Anchored Hearing Aid processors attached to test bands and binaural air conduction hearing aids, in bilateral conductive hearing loss. Fifteen individuals with bilateral symmetrical moderate to moderately severe degree of conductive loss were included in the study. Sound field warble tone thresholds, Speech Identification Scores in quiet as well as in the presence of noise and degrees of errors of horizantal Localization were compared in the two aided conditions. Statistical analysis of data revealed that warble tone thresholds and Speech Identification Scores in quiet and noise were significantly better with bilateral Bone Anchored Hearing Aid processors attached to test bands compared to those with binaural air conduction hearing aids. There was no significant difference. between the degrees of errors of horizantal localization in the two aided conditions.
