The study investigated the effects of six telephone conditions on discrimination in 19 hearing impaired adults. No significant differences were found among the unaided, acoustically coupled, and magnetically coupled listening modes. Ss understood words significantly better using an amplifier handset, regardless of listening mode. (Author/CL)

The Hearing Aid Malfunction Detection Unit is a miniature, add-on device which performs a check of hearing aid operation about every half hour, and which indicates malfunction by means of a highly visible, electrically tripped indicator. (Author/SBH)

To prevent feedback from hearing aids with a large gain (about 65 dB), the use of earmuffs in addition to ear molds is suggested. Young children with hearing losses of 95 dB or greater react more easily to social stimuli when using earmuffs. (JC)

Described is a program of research into sensory aids for the deaf, emphasizing research on factors involved in the effective use of sensory aids rather than evaluation of particular devices. Aspects of the program are the development of a programed testing and training unit, the control of fundamental voice frequency using visual feedback, and…

Intended for parents, the booklet provides a practical guide to the types of learning aids that are helpful to the hearing impaired child. Sections cover the following: an explanation of residual hearing; types of hearing aids and hearing aid equipment; language development aids (brief descriptions are provided for materials in beginning language,…

A remotely activated tactual communication aid is described, and results obtained from tests with the aid on five normal hearing young adults and five profoundly hearing impaired children (8 to 14 years old) are reported. (SBH)

This article briefly describes sensory aids for individuals with hearing impairments, such as the visible speech translator, the cochlear implant, and the digital hearing aid, and identifies common trends. The article stresses factors affecting the development of sensory aids in the past and how these factors are likely to influence the future.…

To investigate impaired residual disciminiation for low-frequency formants and its influence on electronic compensation effectiveness, evaluations were made on impaired discrimination for speech formants, synthetic enhancement of consonants, wearable transposer aids, and a speech perception survey. Results showed that certain persons with severe…

Investigated in a series of experiments with 40 adults (20- to 70-years-old) having bilateral sensorineural hearing impairments was the test-retest reliability of the comfort level method for setting the acoustic gain of hearing aids, and the relationship between the comfort settings utilized in more realistic daily listening situations.…

Presented in part at the Acoustical Society of America meeting (77th, Philadelphia, April, 1969). (Author)

Five commercially available hearing aids were assessed in two settings: using hearing aid test equipment available in most audiology clinics, with the hearing aid on microphone setting; and in a public school classroom, with the hearing aid on telecoil setting and operating with an FM classroom amplification system and a personally sized…
