We hypothesized that the fluctuating hearing loss associated with chronic otitis media with effusion (OME) early in development impacts the frequency weighting of speech. Eleven school-aged children with a history of OME were tested 1 to 2 wks after placement of tympanostomy tubes, and their performance was compared with that of 21 control children. The frequency content of Bamford-Kowal-Bench sentences was manipulated to determine the relative importance of cues in the regions of 1, 2, and 4...

Electrically evoked, auditory potentials were measured from Nucleus cochlear implant users. The speech processor was bypassed and the implanted electronics were controlled directly. A 600 ms train of biphasic current pulses was presented. In experimental conditions, the stimulus train included a change in the stimulating electrode position. The amplitude of the responses that were elicited by this change in electrode location tended to increase as the distance between the two stimulating...

A loudness trisection method of measuring individual loudness functions from loudness judgments was tested on 9 normal-hearing subjects over the 40-80 dB SPL range. The average difference between these data and the loudness function defined by the accepted equations relating loudness and SPL for normal listeners (e.g. ANSI Standard S3.20-1973) was 0.78 dB ignoring sign; the standard deviation of the measurements was approximately 1 dB, compared to 6-8 dB in other studies. This may prove useful..

We interviewed a large general population birth cohort about tinnitus, and assessed their personalities using the Multidimensional Personality Questionnaire. People with tinnitus were more socially withdrawn, stress reactive, alienated, and less Self-Controlled than those without. Amongst people who reported tinnitus, those who were more socially withdrawn, stress reactive, and alienated found their tinnitus more distressing. Our interpretation of the findings rests on the notion that percepts..

This study investigated the consequences of presenting binaural stimuli to mismatched frequency regions in normal-hearing listeners. Temporal envelopes were manipulated to present low frequency timing cues to high frequency auditory channels, and interaural time discrimination thresholds were measured. Sensitivity improved with increasing presentation level, and carrier frequency mismatches reduced sensitivity. These results are interpreted in terms of spread of excitation into binaurally...

To clarify the contribution of the skull contents to the transmission of bone vibratory stimuli, we compared auditory thresholds and DPOAE levels with a bone vibrator placed on various sites of the head. The best audiometric thresholds and DPOAE levels were obtained from the mastoid and the temple. The audiometric thresholds from the eye were similar to those of the forehead and about 10 dB higher than at the best sites. DPOAEs were clearly present when elicited by a combination of...
