Hearing test results of 23 dentists obtained before and after working hours are compared to determine if dentists experience any temporary hearing loss. The aim of the project is to determine whether dental drills cause hearing loss and to document the consequences of the loss. Hearing evaluations include pure-tone audiometry, middle-ear testing, and measurements of otoacoustic emissions. The results are expected to convince dentists of the danger of noise exposure and the need for hearing protection

Book Summary: This book was written for more than 50 million Americans who experience tinnitus - some 2 million disabled by it. Just some of the helpful ideas and simple treatment options in this book that readers can effectively accomplish at home include altering medications or changing diets, using sound therapy such as music, learning techniques for improving concentration through use of positive imagery, and improving sleep patterns by controlling middle-of-the-night thinking. The enormous advantages of this book over other titles on this topic come from the 17 renowned scientists who have contributed to this invaluable consumer resource, one that will make a difference in the lives of readers who suffer from this unfortunate malady.

Excerpt: As accrediting bodies mandate sets of competencies that evolves over time for practitioners, the academic and clinical programs charged with didactic education, clinical practice, and student evaluation must keep pace with the field's scope of practice.

Excerpt: It is often the case that veterans who experience hyperacusis have hearing loss and tinnitus; what sets the patient with PTSD apart is an increased likelihood that will rate sound tolerance problems as more severe than tinnitus and hearing loss.

Intended Audience & Purpose: This conference is intended for otologists, audiologists, hearing aid specialists, psychologists, and nurses, who provide clinical management services for patients with tinnitus. The purpose of this conference is to provide a review of current evaluation and management strategies for the treatment of tinnitus.

BACKGROUND: New and improved methods of feedback suppression are routinely introduced in hearing aids; however, comparisons of additional gain before feedback (AGBF) values across instruments are complicated by potential variability across subjects and measurement methods. PURPOSE: To examine the variability in AGBF values across individual listeners and an acoustic manikin. RESEARCH DESIGN: A descriptive study of the reliability and variability of the AGBF measured within six commercially available feedback suppression (FS) algorithms using probe microphone techniques. STUDY SAMPLE: Sixteen participants and an acoustic manikin. RESULTS: The range of AGBF across the six FS algorithms was 0 to 15 dB, consistent with other recent studies. However, measures made in the participants ears and on the acoustic manikin within the same instrument suggest that across instrument comparisons of AGBF measured using acoustic manikin techniques may be misleading, especially when differences between hearing aids are small (i.e., less than 6 dB). Individual subject results also revealed considerable variability within the same FS algorithms. The range of AGBF values was as small as 7 dB and as large as 16 dB depending on the specific FS algorithm, suggesting that some models are much more robust than others. CONCLUSIONS: These results suggest caution when selecting FS algorithms clinically since different models can demonstrate similar AGBF when averaging across ears, but result in quite different AGBF values in a single individual ear.
