This study investigated the use of the dichotic multiple frequency ASSR technique for characterising normal hearing in a group of infants. A descriptive research design was implemented to describe ASSR thresholds obtained in 10 normal hearing infant ears (3 male, 2 female participants) between the age of 3 and 8 weeks. Normal hearing was controlled for by conducting a DPOAE screening test on al...

In a previous study [1] on vowel rounding anticipatory perception through a fricative consonant stream with a gating paradigm, we discovered that auditory information could be, in this VCV frame, ahead of visual information, and even of audiovisual information (hence A>AV>V). We propose here to extend this experiment to different modality-impaired groups of adults and children, namely: (i) to b...

The masking of speech by amplitude-modulated and unmodulated speech-spectrum noise has been evaluated by the measurement of monaural speech recognition in such noise on young and elderly subjects with normal-hearing and elderly hearing-impaired subjects with and without a hearing aid. Sinusoidal modulation with frequencies covering the range 2-100 Hz, as well as an irregular modulation generate...

The role that sensorineural hearing loss plays in the speech-recognition difficulties of the hearing-impaired elderly is examined. One approach to this issue was to make between-group comparisons of performance for three groups of subjects: (a) young normal-hearing adults; (b) elderly hearing-impaired adults; and (c) young normal-hearing adults with simulated sensorineural hearing loss equivale...

Objective: To develop and evaluate the Mandarin Quick Speech-in-Noise (M-Quick SIN) Test materials in mainland China. Design: Four parts were included in the experiment to (1) develop sentence materials and select equivalent sentences, (2) evaluate the reliability of the lists we grouped afterwards, (3) discuss the formula of SNR loss fitted for M-Quick SIN, and (4) quantify the classification ...

TOP Objective: To compare the recognition of vowels and sentences in noise by cochlear implant patients using a 6-channel, continuous interleaved sampling (CIS) processor and by normal-hearing subjects listening to speech processed in the manner of the implant processor and output as six amplitude-modulated sine waves. Design: Subjects, 11 normal-hearing listeners and 7 cochlear implant patient...

BACKGROUND Hearing impairment is 1 of the 4 most prevalent chronic conditions in the elderly. However, the biological basis of age-related hearing loss is unknown. OBJECTIVE The objective was to test the hypothesis that age-related hearing loss may be associated with poor vitamin B-12 and folate status. DESIGN A thorough audiometric assessment was conducted in 55 healthy women aged 60-71 y....

range—from below the normal threshold of hearing to above the normal level of discomfort or even pain. Most of the time, people with normal hearing can arrange things so that sounds are between their threshold and discomfort levels. This becomes difficult to achieve for people with hearing loss; the difficulty in achieving it increases with the size of the loss. There is an obvious need for hea...
