One-Third Octave Band Augmented Speech Discrimination Testing For Cochlear Impaired Listeners, Dianne Heath

Dissertations and Theses

The purpose of this study was to investigate the effects of a 500 Hz and 3,150 Hz one-third octave band augmentation on the speech discrimination ability of listeners with cochlear hearing impairments. The results were analyzed both within the experimental group of subjects included in the present study and in comparison with data collected on a control group of normal hearing subjects reported earlier.


One-Third Octave Band Augmented Speech Discrimination Testing For Normal Hearing Listeners, Nancy Marie Bowen Jan 1982

One-Third Octave Band Augmented Speech Discrimination Testing For Normal Hearing Listeners, Nancy Marie Bowen

Dissertations and Theses

The purpose of this study was to investigate the effects of a 500 Hz and 3150 Hz one-third octave band augmentation on the speech discrimination ability of normal hearing listeners and whether such effects vary with signal presentation level. The augmented portion of monosyllabic words was systematically varied from 5-55dB above the intensity level of the unfiltered version of the words and presented simultaneously to one ear.
