“…Kodiyath et al showed that individuals with hearing loss derive significant benefits from channel-free hearing aids over multichannel hearing aids in providing temporal cues for signal detection in background noise. 14 In a study comparing the temporal processing skills of 21 individuals with SNHL with channel-free and multichannel hearing aids, except for comodulation masking release-comodulated condition (CMR-CM), there was no statistically significant difference between the two hearing aids for temporal modulation transfer function, gap detection test, and CMR-uncomodulated condition. For the CMR-CM task, the channel-free hearing aid performed statistically significantly better than the multichannel hearing aid.…”

“…In the study of Kodiyath et al, channel-free hearing aids were preferred more by first-time users than experienced users. 14 Mohan and Rajashekhar have shown that while first-time hearing aid users prefer channel-free processing, experienced users prefer multichannel processing. However, no performance difference was observed for first-time and experienced users.…”

Background: Identifying and understanding speech is difficult for individuals with sensorineural hearing loss, especially in noisy environments. Possible causes include less audibility of the signal, impaired temporal resolution and low selectivity of frequency. The hearing aid is the most common option used to minimize the problems faced by individuals with sensorineural hearing loss. Purpose: To investigate the effects of multichannel and channel-free hearing aid signal processing techniques on spectral-temporal resolution and speech understanding in noise. Research Design: A experimental study was used in which the determined tests were applied to the participants. Study Sample: Thirty-four individuals with bilateral symmetrical sensorineural hearing loss between the ages of 18-70 were included in our study. Data Collection and Analysis: Spectral-temporally modulated ripple test, random gap detection test (RDGT) and Turkish matrix test were applied to the participants using multichannel and channel-free hearing aids. All the data obtained were compared statistically in terms of the performances of the hearing aids. Results: There was no significant difference between multichannel and channel-free hearing aids for spectral resolution and speech understanding in noise tests (p>0.05). While there was no significant difference between the two hearing aids for 500 Hz and 4000 Hz RGDT in temporal resolution measurement (p>0.05); for 1000 Hz (p=.045), 2000 Hz (p=.046) and composite RGDT (p=.001), statistically significant better performances were obtained with the channel-free hearing aids. Conclusions: It is thought that faster processing of the incoming signal in the channel-free hearing aids improves the temporal resolution performance. It is predicted that our study findings might help to determine the signal processing technique that will maximize the communication skills of the patients in various conditions.

“…Because most parts of speech are inaudible, or the speech signals themselves are distorted for individuals with hearing loss. The reduced temporal and frequency resolution probably brings out the fact that noise will mask speech more than in people with normal hearing ( Kodiyath et al., 2017 ).…”
