“…There was no systematic increase in variability relative to the time span between the initial and subsequent test sessions. Other authors have reported similar results regarding test-retest variability in the extended-high frequency range using a modified Koss earphone (Fausti, Henry, Hayden, Phillips, & Frey, 1998;Frank, 1990;Frank & Dreisbach, 1991).…”

“…It has been reported that a clinically acceptable intrasubject variability of Ϯ 10 dB was achieved in 94% of the ears in the extended high-frequency region using Sennheiser HDA 250 circumaural earphones, a precursor model of the HDA 200 (Frank, 1990;Frank & Dreisbach, 1991). In the literature, test-retest repeatability for the Sennheiser HDA 200 earphone has only been reported for the extended high-frequency and not for the conventional frequency range (Frank, 2001).…”

Repeatability was similar for both transducer types. Intrasession test-retest repeatability from 0.5 to 12.5 kHz at each individual frequency including the frequency range susceptible to noise-induced hearing loss was excellent for both transducers. Repeatability was slightly, but significantly poorer in the frequency range from 14 to 16 kHz compared with the frequency ranges from 0.5 to 6 or 8 to 12.5 kHz. Measurements in the extended high-frequency range from 8 to 14 kHz, but not up to 16 kHz, may be recommended for monitoring purposes.

“…across all subjects and frequencies average 3.13 dB, which is lower than the s.d. 's from other studies, typically ranging between 5 -10 dB for f s of 8 -20 kHz ͑Beiter et al, 1976;Frank and Dreisbach, 1991͒. One possible reason for the smaller s.d.…”

For most normal-hearing listeners, absolute thresholds increase rapidly above about 16 kHz. One hypothesis is that the high-frequency limit of the hearing-threshold curve is imposed by the transmission characteristics of the middle ear, which attenuates the sound input [Masterton et al., J. Acoust. Soc. Am. 45, 966-985 (1969)]. An alternative hypothesis is that the high-frequency limit of hearing is imposed by the tonotopicity of the cochlea [Ruggero and Temchin, Proc. Nat. Acad. Sci. U.S.A. 99, 13206-13210 (2002)]. The aim of this study was to test these hypotheses. Forward-masked psychophysical tuning curves (PTCs) were derived for signal frequencies of 12-17.5 kHz. For the highest signal frequencies, the high-frequency slopes of some PTCs were steeper than the slope of the hearing-threshold curve. The results also show that the human auditory system displays frequency selectivity for characteristic frequencies (CFs) as high as 17 kHz, above the frequency at which absolute thresholds begin to increase rapidly. The findings suggest that, for CFs up to 17 kHz, the high-frequency limitation in humans is imposed in part by the middle-ear attenuation, and not by the tonotopicity of the cochlea.

High-frequency audiometry: study with normal audiological subjects Resumo / SummaryPesqui sas recentes apontam a Audiometria Tonal de Alta .reqüência (AT-A.) como um instrumento para o diagnóstico precoce de danos auditivos decorrentes de alguns agentes etiológicos principais, como envelhecimento e exposição a drogas ototóxicas e a intensidades elevadas de ruído. Objetivo: Apesar de já existirem várias técnicas desenvolvidas para essa avaliação, algumas não se aplicam à rotina clínica, em função da falta de praticidade e, por vezes, falta de consistên-cia nos resultados. Segundo a literatura, ainda estão por emergir uma metodologia adequada a tal avaliação e valores indicados como referência à normalidade. .orma de Estudo: Clí-nico prospectivo. Material e método: A presente pesquisa observou o comportamento dos limiares auditivos de alta freqüência em indivíduos jovens e audiologicamente normais e analisou variabilidades acústicas, inter e intra-indivíduos, que de acordo com a literatura, podem interferir na estabilidade dos resultados. Conclusão: Com os dados obtidos, pôde-se estabelecer valores de média, desvio padrão e mediana, além de valores mínimos e máximos para cada freqüência. Os testes estatísticos não identificaram diferenças significantes na maioria das análises realizadas (entre sexo, interaurais, variabilidades acústicas e intra-indivíduos, no mesmo dia de testes). A variabilidade dos resultados entre os exames de um mesmo indivíduo, realizados em dias deferentes de testes, mostrou ser significante, sendo as médias dos limiares no segundo dia sempre melhores que as do primeiro dia.
