Insert earphones for speech recognition testing.
نویسندگان
چکیده
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 insert earphones for word recognition tests can have several beneficial effects with respect to cross hearing and masking.

Influence of the type of transducer in profound hearing loss.
BACKGROUND individuals with profound hearing loss may present vibrotactile responses when tested with supra-aural earphones due to the large skull area exposed to vibration in these transducers. AIM to verify the influence of the type of transducer when assessing air conducted pure tone thresholds in individuals with profound sensorineural hearing loss. METHOD 50 individuals, ranging in age...
متن کاملEvaluation of insert earphones for high-frequency bedside ototoxicity monitoring.
Ototoxic hearing loss is usually detected earliest through monitoring of the highest audible frequencies in individuals administered ototoxic medications. Conducting ototoxicity monitoring may require testing patients in the hospital room. This study evaluated the use of insert earphones for obtaining reliable threshold responses at bedside. Twenty adult subjects were tested during two differen...
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...
متن کاملRecognition of speech produced in noise.
A two-part study examined recognition of speech produced in quiet and in noise by normal hearing adults. In Part I 5 women produced 50 sentences consisting of an ambiguous carrier phrase followed by a unique target word. These sentences were spoken in three environments: quiet, wide band noise (WBN), and meaningful multi-talker babble (MMB). The WBN and MMB competitors were presented through in...
متن کاملComparison of Etymotic insert and TDH supra-aural earphones in auditory brainstem response measurement.
There are few systematic comparisons of Etymotic ER-3A insert earphones versus supra-aural earphones in auditory brainstem response (ABR) measurement. We compared ER-3A insert earphones and two types of supra-aural earphones (TDH-39P and TDH-49P) in a group of normal hearing adults. Acoustic analyses revealed spectral and temporal differences among earphones. Behavioral and ABR thresholds to cl...
