Psychoacoustic Speech Tests: A Modified Rhyme Test

Effects of Speech Intensity on the Callsign Acquisition Test (CAT) and Modified Rhyme Test (MRT) Presented in Noise

This study sought to evaluate the effect of speech intensity on performance of the Callsign Acquisition Test (CAT) and Modified Rhyme Test (MRT) presented in noise. Fourteen normally hearing listeners performed both tests in 65 dB A white background noise. Speech intensity varied while background noise remained constant to form speech-to-noise ratios (SNRs) of −18, −15, −12, −9, and −6 dB. Resu...

Some psychoacoustic tests with hearing impaired children

Psychoacoustic tes t s can give valuable information for pedagogical and technical rehabilitation of hearing-impaired subjects. The two tes t s described he re give a contribution to the development of such tests . 1) The intensity-discrimination t e s t showed la rge variations of DI between the subjects and no correlation between DI and hearing los s (more than 85 dB ). m 2) The F1 discrimina...

Psychoacoustic filtering for noisy speech enhancement

A new denoising approach is introduced in this paper. It is based on the fact that denoising may be performed by mimicking the human ear function in order to improve the psychoacoustics appearance of speech signal. In the proposed method, the speech signal is decomposed by using a gammatone filterbank in accordance with ERB scale. Spectral attenuation filtering is then applied in each sub-band ...

Wideband Speech Recovery Using Psychoacoustic Criteria

Manymodern speech bandwidth extension techniques predict the high-frequency band based on features extracted from the lower band.While this method works for certain types of speech, problems arise when the correlation between the low and the high bands is not sufficient for adequate prediction. These situations require that additional high-band information is sent to the decoder. This overhead ...
