Acoustic reflex threshold and loudness discomfort.
OBJECTIVE Trying to find an accurate relation between loudness discomfort level and acoustic reflex threshold. METHODS Seventy patients were involved in this study. Ten normal patients, 30 patients of unilateral conductive hearing loss and 30 patients of unilateral or bilateral, mild to moderate sensorineural hearing loss were tested by 1, 2, KH2 pure tones, 0.5, 1, 2, 4, 8 KHz narrow band no...
متن کاملLoudness balance between electric and acoustic stimulation.
Binaural loudness balance between electric and acoustic stimulation is obtained in auditory brainstem implant listeners who had substantial acoustic hearing in one ear. The data are well described by a linear relationship between acoustic decibels and electric microamps. Based upon this linear relationship, we propose an exponential model of loudness growth in electric stimulation. The exponent...
متن کاملLoudness and acoustic parameters of popular children's toys.
OBJECTIVE This project was conducted to evaluate the loudness and acoustic parameters of toys designed for children. In addition, we investigated whether occluding the toys' speaker with tape would result in a significant loudness reduction; thereby potentially reducing the risk of noise induced hearing loss. METHODS Twenty-six toys were selected after an initial screening at two national ret...
متن کاملThe contour test of loudness perception.
OBJECTIVE This article presents the underlying rationale, normative data, and reliability data for a test of loudness perception (the Contour Test) that was devised for use in clinical hearing aid fitting. The Contour Test yields data describing the sound level required for each of seven categories of loudness ranging from very soft to uncomfortably loud. DESIGN Two experiments are described....
متن کاملLoudness of dynamic stimuli in acoustic and electric hearing.
Traditional loudness models have been based on the average energy and the critical band analysis of steady-state sounds. However, most environmental sounds, including speech, are dynamic stimuli, in which the average level [e.g., the root-mean-square (rms) level] does not account for the large temporal fluctuations. The question addressed here was whether two stimuli of the same rms level but d...
