How does noise affect perception of foreign accented speech? English sentences spoken by non-native talkers with various language backgrounds were presented to native speakers. The Speech Reception Threshold (SRT) was found for 5 different accent classes, and contrasted with noise-free intelligibility. Modest trends towards global differences in intelligibility based on accent class were found,...

Background: Many elderly individuals complain of difficulty in understanding speech in noise despite having normal hearing thresholds. According to previous studies, auditory training leads to improvement in speech-in-noise perception, but these studies did not consider the etiology, so their results cannot be generalized. The present study aimed at investigating the effectiveness of envelope-b...

The aim of this study was to investigate the effect of bilateral hearing aids (HA) in subjects with mild and moderate-to-severe hearing loss. This study was designed as a within-subject feasibility study. Bilateral HA use was assessed using different laboratory tests on speech reception, listening effort, noise tolerance, and localization. All data were evaluated with bilateral and unilateral H...

Background: Speech perception ability depends on auditory and extra-auditory elements. The signal-to-noise ratio (SNR) is an extra-auditory element that has an effect on the ability to normally follow speech and maintain a conversation. Speech in noise perception difficulty is a common complaint of the elderly. In this study, the importance of SNR magnitude as an extra-auditory effect on speech...

In the presence of competing speech or noise, reverberation degrades speech intelligibility not only by its direct effect on the target but also by affecting the interferer. Two experiments were designed to validate a method for predicting the loss of intelligibility associated with this latter effect. Speech reception thresholds were measured under headphones, using spatially separated target ...

Over recent years we tested speech understanding and localization abilities of bilateral CI users with an extensive test battery [1, 2]. Figure 1, top panel, shows results of the speech test for seven bilateral CI users. Speech reception thresholds (SRTs) with speech and noise presented from the front were measured in the free-field. SRTs were between 0 and +6 dB, i.e. performance differed desp...

The aim of the study was to determine signal-to-noise ratio (SNR) for Speech Reception Threshold (SRT) young persons with normal hearing. following three tests available Polish language were used: New Articulation Lists (NAL-93) version 2011, Sentence Test (PST) and Matrix (PSMT). When using PST PSMT masking signal babble noise made material contained in test. For NAL-93 speech noise. reception...
