To investigate the effect of acquired sensorineural hearing loss on speech perception at the acoustic-phonetic level, eight hearingimpaired and eight normally hearing adults were asked to identify and discriminate between a number of synthetic speech stimuli. Two sets of six speech stimuli were used; one set varied in terms of the voicing dimension with endpoint stimuli of “coat” and “goat”, wh...
Objectives: The aim of the present study was to investigate satisfaction levels with hearing aids in daily life of older adult users, in addition to associated factors. Methods & Materials: In this cross sectional study, 32 subjects with moderate to severe sensory neural hearing loss (mean age; 63.5±9.8 Yrs) and different socio-economic status, referred to private practice audiology clinic (...
Background and Objective: One of the most important physical properties of vowels is their formant structure. One of the most obvious speech errors in hearing-impaired children is vowel errors. The present study aimed to determine and compare the formant structure of Persian vowels in deaf and cochlear implant children in the age range of 4-7 years. Materials and Methods: This descriptive-anal...
The influence of voice-onset time (VOT) and vowel-onset characteristics on the perception of the voicing contrast for initial plosive consonants was examined for hearing-impaired children, and normal-hearing children and adults. Listeners identified spoken 'DAD'--'TAD' stimuli controlled for VOT and vowel onset characteristics. Only six of 16 hearing-impaired children appropriately identified t...
3 listeners with sensorineural hearing loss ranging from moderate to moderate-severe starting at frequencies higher than 1 kHz participated in two masking experiments and a partial masking experiment. In the first masking experiment, fM = 1 KHz and LM = 50 dB SPL, higher than normal masked thresholds were obtained for listeners whose hearing was impaired in the frequency region of clear hearing...
Children with hearing impairment show difficulties in sentences derived by Wh-movement, such as relative clauses and Wh-questions. This study examines the nature of this deficit in 48 hearing impaired children aged 9-12 years and 38 hearing controls. The task involved reading aloud and paraphrasing of object relatives that include a noun-verb heterophonic homograph. The correct pronunciation of...
The main purpose of the study was to examine the academic achievement and self-concept of male and female hearing-impaired students in Nigeria. In doing so, a purposive sampling procedure was employed to elicit responses from 566 (364 males and 204 females) hearing-impaired secondary school students identified in various parts of the country. The Adolescent Personal Data Inventory (APDI) was us...
OBJECTIVE This study investigated the reliability, accuracy, and time efficiency of automated hearing assessment using a computer-based telemedicine-compliant audiometer. MATERIALS AND METHODS Thirty normal-hearing subjects and eight hearing-impaired subjects were tested with pure-tone air conduction audiometry (125-8,000 Hz) in a manual and automated configuration in a counterbalanced manner...
Hereditary hearing loss affects a significant proportion of the hearing impaired, with genetic mutations estimated to be responsible for its etiology in over 50% of this population. The methods for molecular diagnostics are changing as a result of the transition from linkage analysis to next generation sequencing to identify the genes responsible for hearing loss in affected families. In this r...
Objectives: Older adults show many difficulties of speech perception in noisy situations due to peripheral and central auditory impairments, and cognitive dysfunctions. One of the most common rehabilitative procedures for older adults with hearing loss is amplification. However, there is some evidence of dissatisfaction of amplification in older adults. Methods & Materials: We assessed cogni...
