“…Additionally, PHL speech perception in noise ability was measured with the Quick Speech in Noise Test (QuickSIN; Killion1 & Niquette, 2000). A speech in noise test was added to the assessment battery because speech in noise ability cannot be predicted based on pure tone thresholds (Preminger et al, 2005), therefore both PTA and speech in noise ability are likely independent predictors of hearing-loss related quality of life. The purpose of the QuickSIN is to determine the lowest signal-tonoise ratio (SNR) where the subject can repeat back 50% of the speech material.…”

The purpose of this research was to investigate the congruent/incongruent perceptions of hearing-loss related quality of life between members of couples and to determine how incongruence was affected by individual psychosocial characteristics, specifically measures of mood (negative affect and positive affect), stress, and communication in the marriage. An exploratory correlational analysis was performed on data for 52 couples in which only one member had a hearing loss. In the regression analyses the independent variables were hearing-loss related quality of life scores measured in people with hearing loss, measured in significant others, and differences in hearing-loss related quality of life among members of a couple. The results demonstrate that both in people with hearing loss and their significant others, perceptions of hearing-loss related quality of life is highly correlated with negative mood scores. Incongruence in hearing-loss related quality of life scores reported by members of a couple were highly correlated with negative affect measured within each individual. Future research evaluating the effectiveness of audiologic rehabilitation can use measures of mood as an outcome variable.

“…The diagnosis of dead cocWear regions currently attracts growing interest, because the condition may significantly affect the rehabilitation strategy (Baer, et al, 2002;Mackersie, et al, 2004;Preminger, et al, 2005;.Vickers, et al, 200 1).…”

Objectives: Assess the feasibility of drawing tuning curves from the masking function of steady state potentials. Develop a noninvasive tool for research applications on cochlear frequency selectivity in sedated animais. Obtain pilot human data validating auditory steady state evoked potential-derived (ASSEP) tuning curves against psychophysical data.,.Design: ASSEP tuning curves were drawn in 10 Beagle puppies and six human adults using amplitude-modulated probes. Two probe frequencies (1 and 2 kHz) were used in dogs and only one (2 kHz) in humans. The modulation rates of the two probes were set to 81 and 88 Hz, respectively. Psychophysical tuning curves were obtained in 12 normal human subjects using the same maskers and either a pure-tone or an amplitude-modulated probe to verity if the latter had a specific effect on tuning curve parameters. Six of these 12 subjects participated in the electrophysiologic measurements. For each tuning curve, the intensity of the narrowband masker required just to mask the fixed probe was plotted for different masker center frequencies. Masker center frequencies extended to about half an octave above and an octave below the probe frequencies in 1DO-Hzsteps. Tuning curve width (010dB values), high-and low-frequency slopes (in dB/octave) and the masker frequency yielding the lowest masking threshold (maximal masker frequency) were computed. Canine 010 dB values obtained were compared with those published for several species with other techniques. For humans, ASSEP and psychophysical tuning curves were directly compared in the same subjects and with published data.Results: ln dogs, the ASSEP method yielded reproducible tUlîing curves with qualitative and quantitative parameters similar to other physiologic measures of tuning obtained in various animais. 010 dB values were greater at 2 than at1 kHz, reflecting the well-known correlation between sharpness of tuning and central frequency. ln humans, ASSEP 010 dB values were slightly smaller than the psychophysical ones, but were greater by a factor of 2 than those obtained with previously published electrophysiologic procedures. ln both species, detuning-a shift of the tip of the curve away from the probe frequency-was frequently observed as upward shifts with a maximal value of 200 Hz. Human psychophysical tuning curves also showed a certain amount of upward detuning. The intraindividual comparison of the two types of probes performed on human sUbjects with the psychophysical method did not indicate a specific effect of the amplitude-modulated probe on the curve parameters. Neither did the intraindividual comparisons indicate that an amplitude-modulated probe per se promoted detuning. Detuning has been observed with several other techniques and is usually attributed to nonlinear interactions between masker and probe in simultaneous masking.Conclusions: The results demonstrate the feasibility of measuring realistic ASSEP tuning curves in sedated dogs and in sleeping human

“…Using the TEN test the number of subjects with DRs among our screened subjects with HFloss (n=105) was 15 (unilateral DRs) and 33 (bilateral DRs); which is in total 46 % Differences in study design and subjects make a direct comparison with earlier studies difficult, but the prevalence of DRs seems similar to that reported by Preminger et al (2005) and Cox et al (2011).…”

Objective: The purpose of this study was to test the ability to discriminate low-frequency pure-tone stimuli for ears with and without contralateral dead regions, in subjects with bilateral high-frequency hearing loss; we examined associations between hearing loss characteristics and frequency discrimination of low-frequency stimuli in subjects with highfrequency hearing loss. Design: Cochlear dead regions were diagnosed using the TEN-HL test. A frequency discrimination test utilizing an adaptive three-alternative forced choice method provided difference limens for reference frequencies 0.25 kHz and 0.5 kHz. Study sample: Among 105 subjects with bilateral high-frequency hearing loss, unilateral dead regions were found in 15 subjects. These, and an additional 15 matched control subjects without dead regions, were included in the study. Results: Ears with dead regions performed best at the frequency discrimination test. Ears with a contralateral dead region performed significantly better than ears without a contralateral dead region at 0.5 kHz, the reference frequency closest to the mean audiogram cut-off, while the opposite result was obtained at 0.25 kHz. Conclusions: Results may be seen as sign of a contralateral effect of unilateral dead regions on the discrimination of stimuli with frequencies well below the audiogram cut-off in adult subjects with bilateral high-frequency hearing loss.Heggdal: Contralateral dead regions and frequency discrimination 1
