Abstract
The purpose of the current study is to determine if the smaller, modern hearing aid has affected the speech intelligibility over the telephone using a telecoil and hearing aid microphone. Six hearing impaired listeners were situated in a quiet office and were asked to repeat aloud Connected Speech Sentences (CST) they heard through the telephone while wearing their hearing aid in telecoil only mode, microphone only mode, and without their hearing aid. The CST sentences were presented in three different signal-to-noise ratios (Quiet, +10dB, & +5dB) with the recorded speech babble of the CST test. It was discovered that the listeners performed, on average, better in all listening conditions without their hearing aid in. However, no statistical significance was seen between any of the test conditions. Implications of this will be discussed.
