This Standard specifies maximum permissible ambient noise levels (MPANLs) allowed in an audiometric test room that produce negligible masking ( 2 dB) of test signals presented at reference equivalent threshold levels specified in ANSI S3.6-1996 American National Standard Specification of Audiometers. The MPANLs are specified from 125 to 8000 Hz in octave and one-third octave band intervals for ...

The Abbreviated Profile of Hearing Aid Benefit (APHAB) is a self-report questionnaire that is used to quantify the impact of a hearing problem on an individual's daily life. In this investigation, the relationships were explored between typical clinical audiometric data and the four subscale scores of the APHAB administered in the unaided (without-amplification) condition. Sixty subjects provid...

This article describes a patient with documented sudden, severe, unilateral, sensorineural hearing loss occurring four days after audiometric evaluation for nonspecific complaints. He was hospitalized immediately; treatment included I.V. histamine and oral steroid therapy. He noted improvement within two days, and serial audiometry has documented recovery to the initial audiometric levels. We b...

Howell, R. W., and Hartley, B. P. R. (1972). Brit. J. industr. Med., 29,432435. Variability in audiometric recording. A study of initial and repeat audiograms by two operators on 143 young male new entrants to industry (free of previous occupational exposure) has shown that mean values (mean of both ears, readings at 3 and 4 kHz) differed significantly between operators, and that this differenc...

introduction: tympanoplasty is the standard and well established procedure for closure of tympanic membrane perforations .this paper compares the results of tympanoplasty in terms of hearing improvement and graft incorporation in patients with chronic perforation of the tympanic membrane between two groups with and without active drainage at the time of surgery.  materials and methods: sixty re...

Distortion product otoacoustic emissions (DPOAE) were measured in normal-hearing and hearing-impaired human subjects. Analyses based on decision theory were used to evaluate DPOAE test performance. Specifically, relative operating characteristic (ROC) curves were constructed and the areas under these curves were used to estimate the extent to which normal and impaired ears could be correctly id...

Introduction: As otology enters the field of gene therapy and human studies commence, the questionarises whether audiograms e the current gold standard for the evaluation of hearing function e canconsistently predict cellular damage within the human inner ear and thus should be used to defineinclusion criteria for trials. Current assumptions rely on the analysis of small groups of h...

OBJECTIVES/HYPOTHESIS To compare hearing measurements made at home using self-administered audiometric software against audiological tests performed on the same subjects in a clinical setting STUDY DESIGN Prospective, crossover equivalence study METHODS In experiment 1, adults with varying degrees of hearing loss (N = 19) performed air-conduction audiometry, frequency discrimination, and sp...
