Background: Cochlear implants have shown vast improvements in speech understanding for those with severe to profound hearing loss; however, music perception remains a challenge for electric hearing. It is unclear whether the difficulties arise from limitations of sound processing, the nature of a damaged auditory system, or a combination of both. Purpose: To examine music perception performance with different acoustic and electric hearing configurations. Research Design: Chord discrimination and timbre perception were tested in subjects representing four daily-use listening configurations: unilateral cochlear implant (CI), contralateral bimodal (CIHA), bilateral hearing aid (HAHA) and normal-hearing (NH) listeners. A same-different task was used for discrimination of two chords played on piano. Timbre perception was assessed using a 10-instrument forced-choice identification task. Study Sample: Fourteen adults were included in each group, none of whom were professional musicians. Data Collection and Analysis: The number of correct responses was divided by the total number of presentations to calculate scores in percent correct. Data analyses were performed with Kruskal-Wallis one-way analysis of variance and linear regression. Results: Chord discrimination showed a narrow range of performance across groups, with mean scores ranging between 72.5% (CI) and 88.9% (NH). Significant differences were seen between the NH and all hearing-impaired groups. Both the HAHA and CIHA groups performed significantly better than the CI groups, and no significant differences were observed between the HAHA and CIHA groups. Timbre perception was significantly poorer for the hearing-impaired groups (mean scores ranged from 50.3–73.9%) compared to NH (95.2%). Significantly better performance was observed in the HAHA group as compared to both groups with electric hearing (CI and CIHA). There was no significant difference in performance between the CIHA and CI groups. Timbre perception was a significantly more difficult task than chord discrimination for both the CI and CIHA groups, yet the easier task for the NH group. A significant difference between the two tasks was not seen in the HAHA group. Conclusion: Having impaired hearing decreases performance compared to NH across both chord discrimination and timbre perception tasks. For chord discrimination, having acoustic hearing improved performance compared to electric hearing only. Timbre perception distinguished those with acoustic hearing from those with electric hearing. Those with bilateral acoustic hearing, even if damaged, performed significantly better on this task than those requiring electrical stimulation, which may indicate that CI sound processing fails to capture and deliver the necessary acoustic cues for timbre perception. Further analysis of timbre characteristics in electric hearing may contribute to advancements in programming strategies to obtain optimal hearing outcomes.

AbstractHearing aids (HAs) are important for the rehabilitation of individuals with hearing loss. Although the rehabilitation of speech communication is well understood, less attention has been devoted to understanding hearing-impaired instrumentalists’ needs to actively participate in music. Despite efforts to adjust HA settings for music acoustics, there lacks an understanding of instrumentalists’ needs and if those HA adjustments satisfy their needs.The purpose of the current study was to explore the challenges that adult HA-wearing instrumentalists face, which prevent them from listening, responding to, and performing music.A qualitative methodology was employed with the use of semistructured interviews conducted with adult amateur instrumentalists.Twelve HA users who were amateur ensemble instrumentalists (playing instruments from the percussion, wind, reed, brass, and string families) and between the ages of 55 and 83 years (seven men and five women) provided data for analysis in this study. Amateur in this context was defined as one who engaged mindfully in pursuit of an activity.Semistructured interviews were conducted using an open-ended interview guide. Interviews were recorded and transcribed verbatim. Transcripts were analyzed using conventional qualitative content analysis.Three categories emerged from the data: (1) participatory needs, (2) effects of HA use, and (3) effects of hearing loss. Participants primarily used HAs to hear the conductor’s instructions to meaningfully participate in music rehearsals. Effects of HA use fell within two subcategories: HA music sound quality and use of an HA music program. The effects of hearing loss fell within three subcategories: inability to identify missing information, affected music components, and nonauditory music perception strategies.Not surprisingly, hearing-impaired instrumentalists face challenges participating in their music activities. However, although participants articulated ways in which HAs and hearing loss affect music perception, which in turn revealed perspectives toward listening using the auditory system and other sensory systems, the primary motivation for their HA use was the need to hear the conductor’s directions. These findings suggest that providing hearing-impaired instrumentalists access to musical experience via participation should be prioritized above restoring the perception of musical descriptors. Future research is needed with instrumentalists who no longer listen to or perform music because of hearing loss, so that the relationship between musical auditory deficiencies and participation can be better explored.

Purpose: Enhancement of musical perception has a positive impact on the emotional stability, quality of life, and aural rehabilitation in individuals with hearing loss. In Korea, however, there are a few test batteries available for properly assessing their abilities to perceive music. The purpose of this study was to develop a evaluation material for the music perception ability, Assessment of Music Perception (AMP) considering the Korean culture and emotion.Methods: A total of 15 normal hearing adults (33.1 ± 11.4 years) were recruited. They performed the AMP which includes eight sub-tests: pitch, melody, rhythm, timbre, and harmony perception test, emotional reaction test, Music listening Attitudes and Satisfaction Questionnaire (MASQ), and Mismatch negativity (MMN).Results: The average percentage of correct answer was 94.0% ± 6.1% in pitch perception test, 94.0% ± 7.1% in melody perception test, 99.3% ± 1.8% in rhythm perception test, 78.9% ± 41.8% in timbre perception test, 96.7% ± 10.4% in emotional reaction test, 85.7% ± 14.1% in harmony perception test. The area of the negative waveform for MMN was 275.27 ± 225.65 μV·ms with the intensity of 70 dBnHL.Conclusion: Considering high scores of a instrument, a developed AMP could be applied for evaluating the music perception ability. However, a little bit of correction for each factor of materials is recommended for comprehensive AMP material. In the future, the music perception ability of the hearing impaired should be evaluated utilizing AMP.

Haptic Stimulation

Cochlear implants (CIs) have been remarkably successful at restoring hearing in severely-to-profoundly hearing-impaired individuals. However, users often struggle to deconstruct complex auditory scenes with multiple simultaneous sounds, which can result in reduced music enjoyment and impaired speech understanding in background noise. Hearing aid users often have similar issues, though these are typically less acute. Several recent studies have shown that haptic stimulation can enhance CI listening by giving access to sound features that are poorly transmitted through the electrical CI signal. This “electro-haptic stimulation” improves melody recognition and pitch discrimination, as well as speech-in-noise performance and sound localization. The success of this approach suggests it could also enhance auditory perception in hearing-aid users and other hearing-impaired listeners. This review focuses on the use of haptic stimulation to enhance music perception in hearing-impaired listeners. Music is prevalent throughout everyday life, being critical to media such as film and video games, and often being central to events such as weddings and funerals. It represents the biggest challenge for signal processing, as it is typically an extremely complex acoustic signal, containing multiple simultaneous harmonic and inharmonic sounds. Signal-processing approaches developed for enhancing music perception could therefore have significant utility for other key issues faced by hearing-impaired listeners, such as understanding speech in noisy environments. This review first discusses the limits of music perception in hearing-impaired listeners and the limits of the tactile system. It then discusses the evidence around integration of audio and haptic stimulation in the brain. Next, the features, suitability, and success of current haptic devices for enhancing music perception are reviewed, as well as the signal-processing approaches that could be deployed in future haptic devices. Finally, the cutting-edge technologies that could be exploited for enhancing music perception with haptics are discussed. These include the latest micro motor and driver technology, low-power wireless technology, machine learning, big data, and cloud computing. New approaches for enhancing music perception in hearing-impaired listeners could substantially improve quality of life. Furthermore, effective haptic techniques for providing complex sound information could offer a non-invasive, affordable means for enhancing listening more broadly in hearing-impaired individuals.

The teachers of 2231 elementary school children were asked to identify those with known or suspected hearing problems. Following screening, the data were compared. Teachers identified 5% of the children as hearing-impaired, while screening identified only 3%. There was agreement between the two procedures on 1%. Subsequent to the teacher interviews, rescreening and tympanometry were conducted. These procedures indicated that teacher screening and tympanometry were in agreement on 2% of the total sample or 50% of the hearing-loss group. It was concluded that teachers could supplement audiometry, particularly when otoscopy and typanometry are not available.
