Fifteen percent of women and 18 percent of men reported permanent tinnitus. Hyperacousis was reported by 43 percent of the musicians. Their ear symptoms affected the usage rate. Hearing protectors were used more often among musicians having ear symptoms than those reporting no symptoms. Sixty percent of musicians reported experiencing stress to some extent, and those with ear symptoms had three to nine times more stress and believed that their working environment was noisier. Thus, the study shows that musicians seldom use hearing protectors before symptoms begin. Although symptoms increased usage rate, the usage levels are still less than ideal. Motivation and training are needed to improve hearing protector use among musicians. 6 figures. 2 tables. 12 references. (AA-M). Subject Category: Hearing. Descriptors: Musicians.

Cochlear Implant Failures and Revision.

Medical Center Drive, Ann Arbor, MI 48109. E-mail: aadon@umich.edu. Language: English. Abstract: This article describes a study that reviewed the cochlear implant failures and revision surgeries at a large university hospital's cochlear implant program to determine the reasons for these failures and revisions. Information on 28 adults and 30 children was reviewed. The institutional device failure rate was 3.7 percent, and the overall revision rate was 5.1 percent. Reasons for implant revision included documented internal device failure (46 percent), scalp flap complications (17 percent), optimization of electrode placement (13 percent), unexplained deterioration of performance (12 percent), technology upgrade (10 percent), and intratemporal pathology (3 percent). Revision surgery typically involved only minor anatomic challenges, but five patients required circumodiolar drillout procedures to improve electrode position. Electrode insertion was equal or deeper in 53 of the 58 cases. Speech perception ability decreased in only three patients. 4 tables. 18 references. (AA-M). Subject Category: Hearing. Speech.

Preoperative Antibiotic and Steroid Therapy and Hearing

Otitis Media.

E-mail: reprints@elsevier.com. Website: www.us.elsevierhealth.com. Language: English. Abstract: This article presents a review of a study that sought to determine whether preoperative administration of antibiotics and corticosteroids can attenuate the severity of hearing loss (HL) with semicircular canal (SC) transection in a guinea pig model of pseudomonas aeruginosa (PA) otitis media (OM). According to the authors, the data and findings indicate that HL caused by SC transection in PA OM may be attenuated with preoperative antibiotic therapy in the guinea pig. This study was presented at the Association for Research in Otolaryngology Midwinter Meeting, Daytona Beach, FL, February 22-26, 2004. Subject Category: Hearing. Descriptors: Hearing Loss Treatment.

Abstract: Digital wireless telephones produce audible and often annoying interference in hearing aids. One issue that arose during the development of an American National Standards Institute standard for measuring the electromagnetic field generated by a wireless telephone was the acoustic signal to interference ratios (SIRs) that are required to achieve various levels of telephone usability. This article describes a study that explored the general question of how much interference is acceptable to hearing aid users in terms of the usability of the telephone. Forty-two hearing aid wearers listened to a telephone conversation through a dummy wireless telephone while interference levels were varied using a second telephone programmed to deliver a controlled electromagnetic field. Real ear recordings of the speech with interference were made at each rating point of usability. Signal analyses of the recordings indicate that, for 90 percent of the participants, SIRs in the 28 to 32 decibel range were needed to achieve a rating of highly usable, SIRS in the 20 to 24 decibel range were needed for a rating of minor limitations on use, and SIRs in the 12 to 15 decibel range were needed for a rating of major limitations on use. 2 figures. 2 tables. 12 references.

Benign Positional Vertigo After Cochlear Implantation.

Author(s): Limb, C. J. Source: Otolaryngology-Head and Neck Surgery. 132(5): 741-5. May 2005. Availability: Available from Elsevier Science. (800) 654-2452. Fax: (212) 633-3820. E-mail: reprints@elsevier.com. Web site: www.us.elsevierhealth.com. Language: English. Abstract: This article reports on a study designed to identify patients who underwent cochlear implantation (CI) and subsequently developed benign positional vertigo (BPV) after the procedure, and to identify any contributing factors. A key finding of the research, according to the authors, BPV is an uncommon development after CI, although it occurs more frequently than in the general population. Subject Category: Balance.

Otoacoustic Emissions: Where Are We Today?

Author(s): Lonsbury-Martin, B. L. Source: The ASHA Leader. (10)4:6-7,19. March 22, 2005. Availability: Available from American Speech-Language-Hearing Association. 10801 Rockville Pike, Rockville, MD 20852. Website: http://www.professional.asha.org. Language: English. Abstract: In this article, the author discusses current research literature and findings associated with otoacoustic emissions (OAEs) and the significant benefits to the clinician of both experimental and theoretical findings. OAEs are defined in the article as sounds that can be measured in the external ear canal following the presentation of an acoustic stimulus. The author points out that, in general, OAEs supply unique information about cochlear function in the presence of hearing problems-a capability that continues to make OAEs valuable response measures in both the clinical and basic hearing sciences and promises to contribute further useful tests to the audiometric-test battery.
