Audiometric records of 213 employees with low noise exposure were selected from the public domain data base underpinning Draft American National Standards Institute (ANSI) S12.13-1991 Standard Evaluating the Effectiveness of Hearing Conservation Programs. Records were selected from an ANSI S12.13 "control" group demonstrating raw audiometric thresholds in 1-dB steps, presumably resulting from s...

Purpose: To evaluate the hearing capacity of children with HIV/AIDS and its association to patient age and time of diagnosis. Methods: This descriptive cross-sectional study included 23 children with HIV/AIDS monitored in two specialized medical centers in Joao Pessoa, Brazil. The children underwent basic audiometric evaluation (audiometry and immittance measurements), and the findings were ana...

Noise generated within hearing aid amplifiers is distracting and, if the level is high enough, may interfere with speech communication. For hearing aid specification and fitting, it is useful to know the acoustic levels at which internal amplifier noise becomes audible and at which it becomes objectionable. This paper reports, for eight subjects with moderate hearing losses, the perceived level...

We performed an audiometric study in 20 patients who underwent surgery of the shoulder region under an interscalene brachial plexus block (IBPB). Bupivacaine 0.75% with adrenaline was given followed by a 24-hr continuous infusion of 0.25% bupivacaine. Three audiometric threshold measurements (0.25-18 kHz) were made: the first before IBPB, the second 2-6 h after surgery and the third on the firs...

Recent studies suggest that the amplification needs of children and adults differ due to differences in perceptual ability. For example, several studies have confirmed that children realize greater benefit from a more audible speech signal (Stelmachowicz, Hoover, Lewis, Kortekaas and Pittman 2000; Stelmachowicz, Pittman, Hoover, Lewis and Moeller 2004), a higher signal-to-noise ratio (Hall and ...

Speech audiometric scores were compared across the age range from 50 to 90 years in 137 subjects selected in such a way that average audiometric thresholds were matched across four age groups. Thus any age-related changes in speech audiometric scores could not be attributed to age-related differences in peripheral hearing sensitivity. Four speech audiometric measures were studied; phonemically-...

The diagnosis of Menière’s disease is based on clinical and audiometric criteria, which, although internationally acknowledged, are still subject to discussion. patient’s history complemented by functional investigations, while in recent years imaging endolymphatic hydrops has been accomplished means nuclear magnetic resonance (NMR).
