Abstract

ABSTRACT
Background and Aim: Some environmental interventions such as babble noise can have difficulty understanding speech. Understanding consonants is the basis for a general understanding of speech. Verbal communication usually occurs in environments where multiple speakers are talking. Much of the consonants in Persian formation of stop and fricative consonants. The aim of this study is to determine the effect of babble noise on the recognition score of stop and fricative consonants.
Materials and Methods: This cross-sectional study was performed on 48 of available males and females equally, aged between 19-24 years with normal hearing. After auditory and speech evaluation, Recognition of stop and fricative consonants in consonant vowel consonant syllable at the presence of bobbling noise was tested.
Results: By increasing the amount of noise the recognition score of stop and fricative consonants at the beginning of the syllable reduced. There was a significant difference between recognition score of stop and fricative consonants at the beginning of the word in the signal to noise ratio of zero, -5 and -10 (p =0.000), However, not found significant differences between the sexes.
Conclusion: Increased babble noise levels significantly reduces the recognition score of stop and fricative consonants, and average recognition score stop consonants in noise affects the over than fricative consonants.
Key Words: stop consonants, fricative consonants, speech in noise, babble noise.
