Speech perception in noise: directional microphones versus frequency modulation (FM) systems.
The major consequence of sensorineural hearing loss (SNHL) is communicative difficulty, especially with the addition of noise and/or reverberation. The purpose of this investigation was to compare two types of technologies that have been shown to improve the speech-perception performance of individuals with SNHL: directional microphones and frequency modulation (FM) systems. Forty-six adult sub...
متن کاملImproving Speech Recognition in Noise: Directional Microphone and FM Systems
Recent estimates suggest that over 29 million individuals in the United States exhibit some degree of hearing impairment (National Institutes of Deafness and Communication Disorders (NIDCD). A major consequence of sensorineural hearing loss (SNHL) is communicative difficulty, especially with the addition of noise and/or reverberation (Dubno, Dirks and Morgan 1984; Hawkins and Yacullo 1984; Sute...
متن کاملSpeech perception in noise using directional microphones in open-canal hearing aids.
BACKGROUND Individuals with impaired hearing find it difficult to understand speech in the presence of background noise--a problem addressed effectively by directional microphones. As open-canal fittings have become increasingly popular in the recent past, so has the debate about the effective directional benefit available from these devices. PURPOSE This study investigates the benefit of dir...
متن کاملFrequency-modulation (FM) technology as a method for improving speech perception in noise for individuals with multiple sclerosis.
Almost half of the population with multiple sclerosis (MS) complains of difficulty hearing, despite having essentially normal pure-tone thresholds. The purpose of the present investigation was to evaluate the effects of frequency-modulation (FM) technology utilization on speech perception in noise for adults with and without MS. Sentence material was presented at a constant level of 65 dBA Leq ...
متن کاملSpeech perception through FM auditory trainers in noise and reverberation.
Speech perception through FM auditory trainers was explored in conditions of noise and reverberation. Special attention was paid to the mode of transmission and individual capabilities of various commercially-available units to handle speech in noise and reverberation. Results indicate an overwhelming advantage of FM transmission for maintaining speech intelligibility in noise and reverberation...
