Effect Of Tinnitus Maskers On Speech Discrimination Among Those Wearing Tinnitus Maskers, John Alexander Chonka

Dissertations and Theses

The purpose of this study was to determine the effect(s) of tinnitus maskers and tinnitus instruments on speech discrimination utilizing a population of subjects who currently have tinnitus and are presently wearing these devices. The hypothesis which guided this investigation states that there is no difference between discrimination scores with and without tinnitus maskers. In an attempt to test this hypothesis, speech discrimination scores were obtained from 26 listeners both in quiet and in the presence of cafeteria noise, with and without use of their tinnitus maskers.

A Comparative Study Of Perceptual Ratings And Fundamental Frequency In Female And Male Esophageal Voices, Anne Terese Heinrich

Dissertations and Theses

This study proposed to determine if male and female esophageal voices were rated in the same manner by naïve listeners. Answers to the following questions were sought:

1. Is there a difference in the social acceptability ratings given to female esophageal voices compared to male esophageal voices, when the speakers are matched for speaking ability?
2. Does a relationship exist between the fundamental frequencies of female esophageal voices and ratings of social acceptability given by naïve listeners?
3. Does a relationship exist between the fundamental frequencies of male esophageal voices and ratings of social acceptability given by naïve listeners?
4. Do male and female …

A Study Of The Perceptual Parameters Of Voice In Aging Females, Barbara Ann Mathers

Dissertations and Theses

An interest in understanding the aging processes, as they relate to voice, has prompted research investigating physiological, acoustical, and perceptual attributes of the aging vocal mechanism. Recently, it has been demonstrated that perceptual parameters, in older male voices, differentiate speakers according to age estimations, as determined by a group of listeners.

The purpose of this study was to determine the perceptual characteristics of the female voice which are associated with perceived age, as contrasted to chronological age.
