OBJECTIVE To introduce and verify an algorithm designed to administer adaptive speech-in- noise testing to a specified reliability at selectable points on the psychometric function. DESIGN Speech-in-noise performances were measured using BKB sentences presented in diffuse babble-noise, using morphemic scoring. Target of the algorithm was a test-retest standard deviation of 1.13 dB within the ...

Synopsis Sensorineural hearing loss, is associated with increased forward and backward masking of weak acoustic sub-segments by strong ones, thereby degrading the reception of important cues for identification of consonants. Employment of inter-aural switching, by splitting the speech temporally and presenting alternate segments to the two ears may help in reducing the effect of temporal maskin...

Through the use of DSP chips and multiple microphones, hearing aids now o2er the possibility of performing signal-to-noise enhancement. Evaluating di2erent algorithms before they are instantiated on a hearing aid is essential. However, commercially available tests of hearing in noise do not allow for speech perception evaluation with a variety of signals, noise types, signal and noise locations...

This study proposes a binaural extension to the multi-resolution speech-based envelope power spectrum model (mr-sEPSM) [Jørgensen, Ewert, and Dau (2013). J. Acoust. Soc. Am. 134, 436-446]. It consists of a combination of better-ear (BE) and binaural unmasking processes, implemented as two monaural realizations of the mr-sEPSM combined with a short-term equalization-cancellation process, and use...

OBJECTIVES Previous studies investigating speech perception in noise have typically been conducted with static masker positions. The aim of this study was to investigate the effect of spatial separation of source and masker (spatial release from masking, SRM) in a moving masker setup and to evaluate the impact of adaptive beamforming in comparison with fixed directional microphones in cochlear ...

OBJECTIVE The objective was to describe the speech intelligibility in noise test results among Dutch teenagers and young adults aged 12-24 years, using a national online speech reception threshold (SRT) test, the Earcheck. A secondary objective was to assess the effect of age and gender on speech intelligibility in noise. DESIGN Cross-sectional SRT data were collected over a 5-year period (20...
