background and aim: different tests have been developed to evaluate reduced ability of speech perception in noise, and the words-in-noise test is one of the easiest ones in terms of speech materials. this study aimed to develop and determine the validity and reliability of the persian version of the words-in-noise (win) test for 7 to 12-year-old children. methods: this research is a tool-making...

introduction: tinnitus is a perception of sound without external source. for complete assessment of tinnitus, central auditory processing abilities should be considered in addition to the routine psychological evaluation of tinnitus characteristics. temporal processing is one of the important auditory skills that are necessary for complex higher level auditory processing.   materials and method...

background: one of the most common complaints expressed by individuals with hearing-impairment is the difficulty in speech perception in background noise. different tests have been developed for the evaluation of reduced ability of speech perception in noise, and the consonant-vowel in noise test is one of the simplest one regard to speech materials. the goal of the present study was developmen...

researchers suggested that the individual fit test be conducted to estimate the protection effectiveness of workers’ hearing protection device (hpd) while working. practically, it is convenient to conduct single, instead of multiple, fit test measurement. this study examined if a single trial of earplug fit test can represent multiple performances. additionally, it investigated how much noise e...

background and aim : the quick speech in noise (q-sin) test have been designed to evalu­ate individuals’ ability to recognize speech in noise. this study established to evaluate the test-retest reliability and equivalency of the five test lists of the persian q-sin test in subjects with sensory hearing loss (shl) and normal hearing individuals. methods : this cross-sectional study was per­forme...

abstract   introduction: conductive hearing loss attenuates and delays sound transmission in the middle ear. it can make variety of central auditory processing disorders; that persists even after resolve of peripheral auditory system problems. one of the aspects of central auditory processing is the temporal processing, which is important for understanding speech, including temporal resolution,...

background : the goal of the present study was to develop and validate the persian version of the acceptable noise level (anl) test in normal, persian-speaking children aged 5-8 years. methods : this tool-making and non-experimental research was conducted in two stages. in the first stage the proper story was selected and recorded after evaluation of its content validity. in the second stage th...

background: noise is defined as unwanted or meaningless sound that apart from auditory adverse health effects may distract attention from cues that are important for task performance. human performance is influenced by many job-related factors and workplace conditions including noise level. objective: to study the effect of noise on human performance. methods: the participants included 40 healt...

background and aim: quick speech in noise (q-sin) test has popularity for evaluating speech recognition in noise. the present study has been paid to build five new persian lists with respect to all possible factors affecting the test, to determine validity of the test and to run five lists for normal hearing subjects and assessment of reliability. methods: to build lists, frequent, familiar and...
