Profile of audiometric thresholds and tympanometric curve of elderly patients.
AIM to analyze the audiological profile of elderly patients seen in a clinic from an audiology school clinic in the city of Belo Horizonte. METHODS we studied all the charts from the patients who underwent audiologic assessment from April of 2004 and August of 2007 in an audiology clinic in the city of Belo Horizonte. RESULTS We studied the 313 audiological tests from patients 60 years of a...
متن کاملEstimating audiometric thresholds using auditory steady-state responses.
Human auditory steady-state responses (ASSRs) were recorded using stimulus rates of 78-95 Hz in normal young subjects, in elderly subjects with relatively normal hearing, and in elderly subjects with sensorineural hearing impairment. Amplitude-intensity functions calculated relative to actual sensory thresholds (sensation level or SL) showed that amplitudes increased as stimulus intensity incre...
متن کاملUsing audiometric thresholds and word recognition in a treatment study.
OBJECTIVES First, to examine a possible limit on significant results imposed by a progressive floor effect for hearing threshold improvement in a treatment study. This floor effect for hearing recovery suggests that if inclusion criteria are not set sufficiently high, the superiority of a treatment group may not be detectable. Second, to examine the outcomes when using two different types of cr...
متن کاملAudiometric Configurations in Children
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 ...
متن کاملVariability in audiometric recording.
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...
