The Output Of Compression Hearing Aids With A Transient Input Signal, Michael Andrew Berg Jan 1989

The Output Of Compression Hearing Aids With A Transient Input Signal, Michael Andrew Berg

Dissertations and Theses

The output characteristics of five compression hearing aids in response to a transient signal were examined to determine if, the input-output function (i.e. output levels of the hearing aid as a function of input level) for a transient signal could be made to approximate that of a continuous signal, by activating the compression circuit with a second signal (activator). Input-output functions for three input compression and two output compression hearing aids were obtained in order to determine if: 1. the automatic gain control (AGC) was activated by the second signal and the transient signal output approximates that of a continuous …


A Comparison Of The Expressive Speech Of Profoundly Hearing-Impaired Children : "Hearing Aids On" Versus "Hearing Aids Off", James Allen Henry Jul 1987

A Comparison Of The Expressive Speech Of Profoundly Hearing-Impaired Children : "Hearing Aids On" Versus "Hearing Aids Off", James Allen Henry

Dissertations and Theses

This investigation was conducted to determine whether the removal of hearing aids from these children for eighteen hours (+ 1/2 hour and including sleep time) would result in reduced speech intelligibility as perceived by a panel of listening judges who were unfamiliar with the speech of the deaf.


Relationship Between Electrical And Acoustical Characteristics Of Amplification Systems And Reduced Auditory Sensitivity, Carolyn Margaret Normoyle Jan 1972

Relationship Between Electrical And Acoustical Characteristics Of Amplification Systems And Reduced Auditory Sensitivity, Carolyn Margaret Normoyle

University of the Pacific Theses and Dissertations

Current methods of selection of amplification are not readily applicable to children, and relatively few alternatives have been explored. Consequently, the audiologist must make a number of rather arbitrary judgements with little concrete information to support his recommendation of a given instrument. He has limited means of clinically determining the sustainability of the instrument for the child.

This study was designed to explore the relationship between several factors which may add to the existing body of data related to the problems of amplification in children. In brief, the problem was to determine the various electrical and acoustical characteristics of hearing …
