A cross sectional survey of 581 TA personnel from Wales, the Midlands and Scotland was performed. The aim was to determine their hearing levels, to attempt to relate any degree of noise induced hearing loss detected with military, occupational and leisure noise and to make recommendations to improve the existing Army Hearing Conservation Programme. Each subject answered a questionnaire, had a c...

OBJECTIVE To investigate the compression of the vestibulocochlear nerve in the etiology of the tinnitus in the normal hearing ears with temporal bone computed tomography scans. METHODS A prospective nonrandomized study of 30 bilateral tinnitus and 30 normal hearing patients enrolled in this study. RESULTS A total of 60 patients (ages ranged from 16 to 87) were included. The tinnitus group c...

When the e a r i s stimulated by high-intensity lowfrequency sounds by means of ordinary earphones a sound p res su re is reached were tacti le receptors a r e stimulated. Different attempts have been made to establish the audiometric threshold of this tactile sensation. During pure-tone audiometry i t was observed that some severely hard of hearing and profoundly deaf subjects could give three...

BACKGROUND The relation between the auditory steady-state response (ASSR) and behavioral audiometric thresholds requires further clarification in the case of adults with auditory neuropathy/auditory dys-synchrony (AN/AD). PURPOSE The aim of this study was to compare pure-tone audiometric threshold (PTAT) and ASSR in adults with AN/AD. STUDY SAMPLE Sixteen adult participants (32 ears) with A...

BACKGROUND Polyamines (e.g., putrescine, spermidine, and spermine) are required for optimal cell growth. Inhibition of polyamine synthesis suppresses carcinogen-induced epithelial cancers, including colon cancer, in animal models. In a short-term phase IIa trial, we determined that low doses of alpha-difluoromethylornithine (DFMO), an inhibitor of ornithine decarboxylase (an enzyme involved in ...

The aim of this study was to assess the relative importance of cochlear mechanical dysfunction, temporal processing deficits, and age on the ability of hearing-impaired listeners to understand speech in noisy backgrounds. Sixty-eight listeners took part in the study. They were provided with linear, frequency-specific amplification to compensate for their audiometric losses, and intelligibility ...

OBJECTIVE To study the long-term results (use, care, satisfaction, ear infections, and audiometry) of the application of a bone-anchored hearing aid (BAHA) to patients with conventional indications who had previously used air-conduction hearing aids. DESIGN Follow-up study (mean duration, 9 years). SETTING Tertiary referral center. PATIENTS The study population comprised 27 patients with ...

Comprehensive audiometric testing serves as the cornerstone of adult hearing aid fittings for many clinicians. The data will serve to define the degree, configuration, and site of lesion of the hearing loss. The data will be used in prescriptive formula to preset the hearing aid and may be entered into probe microphone or hearing aid test box equipment to provide verification targets. Clinician...

Age-related hearing loss (ARHL) is marked by audiometric hearing deficits that propagate along the auditory pathway. Neurochemical changes as a function of aging have also been identified in neurons along the auditory pathway in both rodents and carnivores, however, very little is known about how these neurochemicals change in the non-human primate. To examine how these compensatory neurochemic...

Background and objectives: Type I tympanoplasty is a common otologic surgery which aims to repair the eardrum integrity. Different views have been reported concerning this procedure in young ages and the best moment to perform surgery remains controversial. Surgery in early adolescence appears to achieve the same outcomes than adulthood and without disadvantages of childhood. Characteristics of...
