Particularly when considering hearing aid services for adult listeners, careful consideration has to be given to the particular form and application of inferences drawn from speech identification procedures if erroneous conclusions are to be avoided. It is argued that four such components relate to the statistical properties and discriminatory leverage of speech identification procedures, the choice of presentation level and conditions in regard to the auditory environment experienced by hearing-impaired clients, the extent to which speech tests based on segmental intelligibility provide appropriate information in relationship to perceived disabilities and handicaps, and the ways in which speech identification procedures to evaluate the potential benefits of signal-processing schemes for hearing aids are dependent upon sufficient listening experiences. Data are drawn from the literature to illuminate these points in terms of application in clinical practice and clinical evaluation exercises, and also with regard to future research needs.","PeriodicalId":76517,"journal":{"name":"Scandinavian audiology.

{"title":"Interactive effects of aging with noise induced hearing loss.","authors":"J M Miller, D F Dolan, Y Raphael, R A Altschuler","doi":"","DOIUrl":"","url":null,"abstract":"Aging is associated with a down-regulation in metabolism, which may underlie an increased sensitivity to stress agents and a decreased repair of tissues following stress. In the auditory system this could lead to increased sensitivity to noise induced hearing loss (NIHL) with age. This study examines the effects of high intensity noise exposure (0.5-40 kHz noise at 108 dB SPL for 45 min) on young and old normal (CBA/Ca) mice and young premature presbycusis (C57BL/6) mice. Tone evoked auditory brainstem response (ABR) audiograms were obtained before and after the exposure. The animals were sacrificed and cytocochleograms were performed. The ABR threshold shifts and hair cell losses which followed noise exposure increased with increasing age in the normal (CBA/Ca) mice. Subjects which showed early presbycusis (C57BL/6) associated with vascular pathology, showed an increased sensitivity to noise induced hearing loss over normal subjects. Interestingly, in some cases the physiological loss in C57BL/6 mice was not associated with hair cell loss. These findings support the view that aging with or without hearing loss increased the sensitivity of the ear to NIHL. However, it seems that other factors may contribute to NIHL in the animals with premature presbycusis.","PeriodicalId":76517,"journal":{"name":"Scandinavian audiology.

During the following weeks, when the hair cells and tectorial membrane were regenerating, psychophysical and electrophysiological measures were obtained to assess the time course and degree of recovery. Immediately after the exposure, the behavioral thresholds were elevated 30-40 dB and auditory temporal integration was greatly reduced; however, both measures fully recovered by 28 days post-exposure. In addition, tone-on-tone masking patterns recovered to normal. Immediately after the exposure, the thresholds of single cochlear ganglion neurons were elevated more than 30 dB, tuning curves were broader than normal, two-tone rate suppression (TTRS) boundary slopes were shallower than normal and spontaneous activity was reduced. Threshold and spontaneous discharge rate fully recovered after the exposure. Tuning and TTRS also recovered significantly in most neurons; however, some units with characteristic frequencies (CFs) near the exposure frequency showed abnormal tuning and TTRS suppression. The regeneration of the hair cells and lower honeycomb layer of the tectorial membrane is associated with considerable recovery of function; however, the incomplete recovery of tuning and TTRS in some neurons may be linked to the incomplete regeneration of the tectorial membrane.","PeriodicalId":76517,"journal":{"name":"Scandinavian audiology.

All three provided individual frequency shaping via a seven-band low-power filterbank and compression in two channels. RangeEar and DynEar used wide dynamic range syllabic compression in the low-frequency (LF) channel, while LinEar used compression limiting. In the high-frequency (HF) channel, RangeEar used a slow-acting automatic volume control, while DynEar and LinEar used compression limiting. Wearable digital signal processing-based experimental instruments were used to evaluate the fitting algorithms under real world conditions with experienced hearing aid users. Evaluation included laboratory testing of speech recognition in noise and questionnaires on sound quality ratings. Results did not indicate one general good-for-all algorithm, but different algorithms resulting in preference and performance depending on the hearing loss configuration. Preference for any of the new algorithms could be predicted based on auditory dynamic range measurements. It was hypothesized that the different preferences were affected by different susceptibility to masking of HF sounds by amplified LF sounds.","PeriodicalId":76517,"journal":{"name":"Scandinavian audiology.
