Comparison of pure-tone audibility thresholds obtained with audiological and two-interval forced-choice procedures.
Audibility thresholds were measured at 500 and 4000 Hz with a standard clinical procedure and a two-interval, forced-choice (2IFC) adaptive procedure for 72 normal-hearing and hearing-impaired listeners, age 17 to 83. Psychometric functions were obtained for clinical, 2IFC, and Yes-No procedures. A measure of response bias was obtained from the Yes-No procedure. The 2IFC adaptive thresholds wer...
متن کاملDistribution characteristics of normal pure-tone thresholds.
OBJECTIVE This study examined the statistical properties of normal air-conduction thresholds obtained with automated and manual audiometry to test the hypothesis that thresholds are normally distributed and to examine the distributions for evidence of bias in manual testing. DESIGN Four databases were mined for normal thresholds. One contained audiograms obtained with an automated method. The...
متن کاملNBS-9A coupler-to-eardrum transformation: TDH-39 and TDH-49 earphones.
A transformation was derived to convert sound-pressure levels referenced to an NBS-9A coupler to corresponding eardrum sound-pressure levels. It was found that the same transformation may be used for male and female adults and for both TDH-39 and TDH-49 earphones in MX-41/AR supra-aural cushions. It was determined that from 250-2000 Hz the transformation provides an eardrum sound-pressure level...
متن کاملMemr Measurements Obtained with a Pure-tone Probe
43S Middle ear muscle reflex (MEMR) measurements have been a part of the standard clinical immittance test battery for decades as a cross-check with the behavioral audiogram and as a way to separate cochlear from retrocochlear pathologies. MEMR responses are measured in the ear canal by using a probe stimulus (e.g., single frequency or broadband noise) to monitor admittance changes elicited by ...
متن کاملInfluence 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...
