background and aim: speech understanding almost never occurs in silence. verbal communication often occurs in environments where multiple speakers are talking. in such environments, babbling noise masks speech comprehension. consonants, in comparison to vowels, are more sensitive to noise masking. consonants provide most acoustic information needed for comprehending the meaning of the word. sin...

Studies of speech perception in various types of background noise have shown that noise with linguistic content affects listeners differently than nonlinguistic noise [e.g., Simpson, S. A., and Cooke, M. (2005). "Consonant identification in N-talker babble is a nonmonotonic function of N," J. Acoust. Soc. Am. 118, 2775-2778; Sperry, J. L., Wiley, T. L., and Chial, M. R. (1997). "Word recognitio...

The aim of the study was to assess speech recognition in noise using multitalker babble of native and non-native language at two different signal to noise ratios. The speech recognition in noise was assessed on 60 participants (18 to 30 years) with normal hearing sensitivity, having Malayalam and Kannada as their native language. For this purpose, 6 and 10 multitalker babble were generated in K...

This study was intended to determine whether the effects of noise on English listening comprehension would vary among Chinese college students with different learning styles. A total of 89 participants with different learning styles measured using Kolb's (1985) Learning Style Inventory finished English listening comprehension tests in quiet and in white noise, Chinese two-talker babble, and Eng...

ABSTRACT Objective: to analyze speech perception in normally hearing adults when listening silence and with different types of noise. Methods: 40 individuals both sexes, aged 18 45 years, participated the study. Speech was assessed Lists Sentences Portuguese test, without a competing noise speech-spectrum, babble, cocktail party A mixed-effects linear regression model 95% confidence interval we...

Acceptable noise level (ANL) is defined as the maximum level of background noise that an individual is willing to accept while listening to speech. The type of background noise does not affect ANL results with the possible exception of music. The purpose of this study was to determine if ANL for music was different from ANL for twelve-talker babble and investigate if there was a correlation bet...

The results of transient evoked otoacoustic emissions (TEOAEs) have been found to be adversely affected by noise. However, there are few investigations into the specific effect of background noise on TEOAEs. The purpose of the present study was to determine the effects of increasing levels of speech babble and the recording method on TEOAEs using the ILO88 Otodynamics instrumentation. Subjects ...

Speech communication commonly occurs in the presence of noise. Perceptual errors in the perception of noise-masked speech vary as a function of noise type (e.g., white noise, speech-shaped noise, multi-talker babble), listener characteristics (e.g., listeners with hearing loss, non-native listeners), and target stimulus properties (e.g., native language of the talker, casual vs clear speech). T...

Speech babble is one of the most challenging noise interference due to its speaker/speech like characteristics for speech and speaker recognition systems. Performance of such systems strongly degrades in the presence of background noise, like the babble noise. Existing techniques solve this problem by additional processing of speech signal to remove noise. In contrast to existing works, the aim...

Speech in ecological environments is often accompanied by noise, which often proposes challenges to listeners. In this study we examined differences in native Mandarin-speaking and native English-speaking adults’ ability to perceive lexical tones and vowels in white noise and multi-talker babble noise at different signal-to-noise ratios. We found that although white noise impaired both listener...
