This study investigated mid-vocalic F1 and F2 frequencies as cues to the perception of three Cantonese vowels (/a/, /i/, /Á/) in monosyllabic words produced by ten profoundly hearing impaired and ten normal hearing adolescents. For the control group, there were significant differences in F1 and F2 frequencies among the three vowels as expected. In contrast, the hearing impaired speakers did not...

With the emphasis on quality assurance and patient satisfaction in health care, decision making in rehabilitative audiology is a critical issue. Traditionally, rehabilitative decisions have been based on questionable assessment procedures and unproven treatment methods. In this paper, current strategies for decision making with hearing-impaired adults will be presented. Discussion will focus on...

PURPOSE To compare the prevalence of refractive errors, amblyopia, and strabismus between hearing-impaired and normal children (7-22 years old) in Mashhad. METHODS In this cross-sectional study, cases were selected from hearing-impaired children in Mashhad. The control group consisted of children with no hearing problem. The sampling was done utilizing the cluster sampling method. All of the ...

OBJECTIVES/HYPOTHESIS Hypernasality is considered a prevalent speech abnormality that could significantly contribute to the unintelligibility of the hearing-impaired speakers. The aim of this study was to evaluate the effect of cochlear implantation and the duration of hearing loss on nasalance of speech of a postlingually impaired group of Saudi adult patients. STUDY DESIGN Retrospective stu...

Timbre is a combination of all auditory object attributes other than pitch, loudness and duration, and is used to distinguish different musical instruments or voices. People with sensorineural hearing loss often have problems with timbre distortion. Even for modern hearing aids it is difficult to provide good audio quality for speech intelligibility while preserving the natural timbre. This not...

Three modifications of a psychoacoustically and physiologically motivated processing model [Dau et al., J. Acoust. Soc. Am. 102 (1997a) 2892-2905] are presented and tested. The modifications aim at simulating sensorineural hearing loss and incorporate a level-dependent peripheral compression whose properties are affected by hearing impairment. Model 1 realizes this difference by introducing for...

OBJECTIVE Hearing impairment has been suggested to increase the risk of falls. However, most previous studies were conducted in an older population without classification of the fracture regions. This study aimed to delineate the risk of each fracture type in all age populations. METHODS The Korean National Health Insurance Service-National Sample Cohort was collected from 2002 to 2013. A tot...
