Medidas de imitância acústica de banda larga com estímulo chirp e tom puro em lactentes com normalidade de orelha média

Abstract

The reflectance values were shown to be greater for low frequencies, reducing to medium ones and increasing once again to high frequencies, while the absorbance values displayed an opposite behavior. No significant difference was verified between chirp and pure tone stimuli. Conclusion:A typical behavior of the measures, characterized by a higher reflectance at low frequencies and higher absorbance at medium frequencies was observed in the population studied. Observou-se um comportamento típico das medidas estudadas, caracterizado por maior reflectância nas frequências graves e maior absorvância para as frequências médias.Descritores: Orelha média; Testes de impedância acústica; Perda auditiva condutiva; Otite média; Audiologia This study was held at
