Insert earphones for speech recognition testing.
Performance-intensity functions for PB word lists were run on 19 normal-hearing subjects and 15 subjects with sensorineural hearing losses. Comparisons were made between standard supra-aural earphones (TDH-49P) and insert phones (ER-3A). Results showed that, at least for the higher sensation levels where word recognition tests are usually performed, the phones may be used interchangeably. Using...
متن کاملSpectral peak resolution and speech recognition in quiet: normal hearing, hearing impaired, and cochlear implant listeners.
Spectral peak resolution was investigated in normal hearing (NH), hearing impaired (HI), and cochlear implant (CI) listeners. The task involved discriminating between two rippled noise stimuli in which the frequency positions of the log-spaced peaks and valleys were interchanged. The ripple spacing was varied adaptively from 0.13 to 11.31 ripples/octave, and the minimum ripple spacing at which ...
متن کاملSpeech recognition in noise by hearing-impaired and noise-masked normal-hearing listeners.
A prevailing complaint among individuals with sensorineural hearing loss (SNHL) is difficulty understanding speech, particularly under adverse listening conditions. The present investigation compared the speech-recognition abilities of listeners with mild to moderate degrees of SNHL to normal-hearing individuals with simulated hearing impairments, accomplished using spectrally shaped masking no...
متن کاملThe use of circumaural earphones in audiometry.
Four circumaural muffs were compared with the phone/cushion device nowstandard for audiometry, the Willson "Sound-Barrier", the Maico "Auraldome",and 2 versions of the Tracor "Otocup". Psychoacoustic loudness balancingby normal subjects was performed, and physical measurements by probe-tubemicrophone and by flat-plate coupler. Neither physical method was relatedclosely enoug...
متن کاملInteraural attenuation using insert earphones: electrocochleographic approach.
We measured the interaural attenuation for click stimuli using insert earphones. Electrocochleographic thresholds were determined when clicks were presented both ipsilaterally and contralaterally to the recording ear. The interaural attenuation was calculated as the difference between ipsilateral and contralateral thresholds. Results from normal listeners showed that crossover occurred. Results...
