AbstractSubstantial loss of cochlear function is required to elevate pure-tone thresholds to the severe hearing loss range; yet, individuals with severe or profound hearing loss continue to rely on hearing for communication. Despite the impairment, sufficient information is encoded at the periphery to make acoustic hearing a viable option. However, the probability of significant cochlear and/or neural damage associated with the loss has consequences for sound perception and speech recognition. These consequences include degraded frequency selectivity, which can be assessed with tests including psychoacoustic tuning curves and broadband rippled stimuli. Because speech recognition depends on the ability to resolve frequency detail, a listener with severe hearing loss is likely to have impaired communication in both quiet and noisy environments. However, the extent of the impairment varies widely among individuals. A better understanding of the fundamental abilities of listeners with severe and profound hearing loss and the consequences of those abilities for communication can support directed treatment options in this population.

The present study examined the phenomenon of acclimatization in persons with a severe-to-profound hearing loss. A secondary purpose was to examine the efficacy of a digital nonlinear power hearing aid that has a low compression threshold with expansion for this population. Twenty experienced hearing aid users wore the study hearing aids for three months and their performance with the study hearing aids was evaluated at the initial fitting, one month, and three months after the initial fitting. Performance of their current hearing aids was also evaluated at the initial fitting. Speech recognition testing was conducted at input levels of 50 dB SPL and 65 dB SPL in quiet, and 75 dB SPL in noise at a +10 SNR. Questionnaires were used to measure subjective performance at each evaluation interval. The results showed improvement in speech recognition score at the one-month evaluation over the initial evaluation. No significant improvement was seen at the three-month evaluation from the one-month visit. In addition, subjective and objective performance of the study hearing aids was significantly better than the participants' own hearing aids at all evaluation intervals. These results provided evidence of acclimatization in persons with a severe-to-profound hearing loss and reinforced the precaution that any trial of amplification, especially from linear to nonlinear mode, should consider this phenomenon.

Speech Information

This study investigated whether there are limitations on the benefit of providing audible speech information to listeners with high-frequency hearing loss. In a group of 10 listeners with various degrees of high-frequency hearing loss, speech recognition was tested across a wide range of presentation levels. For each of these listeners with hearing loss, recognition performance reached an asymptote of <100%. When the spectrum of the speech for this asymptotic performance level was compared with the listener's pure-tone thresholds, it was seen that providing audible speech to high-frequency regions (≥3000 Hz), where hearing loss exceeds 55 dB HL, tended to produce little or no improvement in recognition scores. In contrast, providing audible speech to lower frequency regions for a listener with a flat, severe-to-profound hearing loss did show improvement with increasing speech audibility, despite this listener's thresholds being greater than 55 dB HL. The present study adds further support to the idea that attempting to provide amplification to regions with severe high-frequency hearing loss (≥3000 Hz) may not necessarily benefit many individuals with hearing loss.

Abstract Objective: CI (cochlear implantation) candidacy is somewhat controversial in severe hearing loss among tonal mandarin-speaking patients. To assess the relationship between pure tone audiometry (PTA) and speech recognition score (SRS), with and without hearing aid amplification, among patients who did not meet the NIH criteria of CI candidacy in tonal language mandarian-speaking countries, especially those with severe hearing loss (70 dB HL < 4FPTA(0.5, 1, 2, 4 KHz) ≤ 90 dB HL) Materials and Methods: A total of 414 patients with sensorineural hearing loss with 774 ears were reviewed retrospectively in a tertiary referral center. The Mandarin Monosyllable Recognition Test (MMRT) was used to evaluate the SRS of these ears. Results: 31% (10/32) of the 32 ears with severe hearing loss, 70-90 dB HL, still showed poor speech recognition (SRS<30%) after hearing aid amplification, while 71% (46/65) of the 65 ears with profound hearing loss, > 90 dB HL, showed poor speech recognition with hearing aid amplification. Conclusions: The speech audiometry with Mandarin Monosyllable Recognition Test (MMRT) helped identify those patients whose 4FPTA< 90 dB HL fell outside the CI candidacy criteria of NIH in tonal language mandarin-speaking countries but showed significantly poor (SRS< 30%) speech recognition performance.

Learning To Listen

Abstract Learning to listen and speak are well-established preludes for reading, writing, and succeeding in mainstream educational settings. Intangibles beyond the ubiquitous test scores that typically serve as markers for progress in children with hearing loss are embedded in descriptions of the educational and social development of four young women. All were diagnosed with severe-to-profound or profound hearing loss as toddlers, and all were fitted with hearing aids and given listening and spoken language therapy. Compiling stories across the life span provides insights into what we can be doing in the lives of young children with hearing loss.

This study investigated the perception and learning of relative pitch using vibrotactile stimuli by musicians with and without a hearing impairment. Notes from C3 to B4 were presented to the fingertip and forefoot. Pre- and post-training tests in which 420 pairs of notes were presented randomly were carried out without any feedback to participants. After the pre-training test, 16 short training sessions were carried out over six weeks with 72 pairs of notes per session and participants told whether their answers were correct. For amateur and professional musicians with normal hearing and professional musicians with a severe or profound hearing loss, larger pitch intervals were easier to identify correctly than smaller intervals. Musicians with normal hearing had a high success rate for relative pitch discrimination as shown by pre- and post-training tests, and when using the fingertips, there was no significant difference between amateur and professional musicians. After training, median scores on the tests in which stimuli were presented to the fingertip and forefoot were >70% for intervals of 3–12 semitones. Training sessions reduced the variability in the responses of amateur and professional musicians with normal hearing and improved their overall ability. There was no significant difference between the relative pitch discrimination abilities between one and 11 semitones, as shown by the pre-training test, of professional musicians with and without a severe/profound hearing loss. These findings indicate that there is potential for vibration to be used to facilitate group musical performance and music education in schools for the deaf.

The auditory system allows the estimation of the distance to sound-emitting objects using multiple spatial cues. In virtual acoustics over headphones, a prerequisite to render auditory distance impression is sound externalization, which denotes the perception of synthesized stimuli outside of the head. Prior studies have found that listeners with mild-to-moderate hearing loss are able to perceive auditory distance and are sensitive to externalization. However, this ability may be degraded by certain factors, such as non-linear amplification in hearing aids or the use of a remote wireless microphone. In this study, 10 normal-hearing and 20 moderate-to-profound hearing-impaired listeners were instructed to estimate the distance of stimuli processed with different methods yielding various perceived auditory distances in the vicinity of the listeners. Two different configurations of non-linear amplification were implemented, and a novel feature aiming to restore a sense of distance in wireless microphone systems was tested. The results showed that the hearing-impaired listeners, even those with a profound hearing loss, were able to discriminate nearby and far sounds that were equalized in level. Their perception of auditory distance was however more contracted than in normal-hearing listeners. Non-linear amplification was found to distort the original spatial cues, but no adverse effect on the ratings of auditory distance was evident. Finally, it was shown that the novel feature was successful in allowing the hearing-impaired participants to perceive externalized sounds with wireless microphone systems.
