The Effect Of Masking On The Acoustic Reflex Threshold, Nancy E. Aldrich

Loma Linda University Electronic Theses, Dissertations & Projects

This study investigated the effect of masking noise on the threshold for stapedial reflex. It has been shown that masking which shifts the hearing threshold causes a loudness function typical of recruitment. It was hypothesized that the stapedial reflex threshold remains the same in a masked situation as in the unmasked situation . It was suggested that this demonstrates recruitment in that the presence of noise reduces the range between hearing thresholds and stapedial reflex thresholds.

Ten subjects, with no known hearing loss or pathology involving the ear or reflex arc were used in this study. A 1000 Hz tone …

Loma Linda University Electronic Theses, Dissertations & Projects

[Abstract Not Included - Preface Included Here]

Otosclerosis is a frequent affliction resulting in progressive hearing loss. With the advance of ear surgery during the past 25 years various procedures have been proposed for the correction of this condition. Among their number surgical mobilization of the stapes has assumed considerable importance. In this paper, which is presented as a thesis to fulfill the requirements for the degree of Master of Science, the operation will be discussed on the basis of the literature and the author's own experiences with the procedure.
