The purpose of this questionnaire study was to evaluate the existing knowledge of binaural hearing and the attitudes and practices of prescribing bilateral hearing aids amongst otolaryngologists in the United Kingdom. Of the 950 questionnaires sent to the current members of the British Association of Otolaryngologists and Head and Neck Surgeons (BAO-HNS), there were 591 respondents (62 per cent). The true response rate with completed questionnaires was 59 per cent. Eighty-one per cent of the respondents were aware of the importance of binaural hearing and had a positive attitude towards binaural fitting. The practice of bilateral hearing aid prescriptions was found to be poor amongst all grades on the NHS (less than 10 per cent of all hearing aid prescriptions). This practice in the private sector was variable, dependent largely on patient preference and affordability. The practice of binaural prescription was higher for patients in the paediatric age group than amongst adults. Two common indications for hearing aid prescriptions for unilateral deafness were otitis media with effusion in children (23 per cent of respondents) and for tinnitus masking in adults (12 per cent of respondents). Many otolaryngologists believed that there was not enough evidence to support bilateral bone-anchored hearing aid implantation and bilateral cochlear implantation. Ninety-four per cent of the respondents believed that binaural hearing was as important as binocular vision.

Hearing Aid Use

Background: Unilateral sensorineural hearing loss (USNHL) can have a negative impact on functions associated with the advantages of balanced, binaural hearing. Although single-sided deafness, which is a complete loss of audibility in one ear, has gained increased interest in the published research, there is a gap in the literature concerning hearing aid outcomes for individuals with residual, or otherwise “aidable,” hearing in the affected ear. Purpose: To assess hearing aid outcomes for a group of individuals with USNHL with residual, aidable function. Research Design: A quasi-experimental study of hearing aid outcomes with paired comparisons made between unaided and aided test conditions. Study Sample: A convenience sample of twenty-two individuals with USNHL, with sufficient residual hearing in the affected ear as to receive audibility from use of a hearing aid, were recruited into the study from September 2011 to August 2012. Intervention: Each participant was fit with a digital behind-the-ear hearing aid coupled to a custom ear mold. Data Collection and Analysis: Assessments were performed at baseline (unaided) and after a three-month field trial (aided) with primary outcomes involving objective measures in sound field yielding signal-to-noise ratio loss (SNR Loss) via the Quick Speech-in-Noise Test and word recognition scores (WRS) via the Northwestern University Auditory Test, No. 6. Outcomes also involved the administration of two well-established subjective benefit questionnaires: The Abbreviated Profile of Hearing Aid Benefit (APHAB) and the 49-item Speech, Spatial, and Qualities of Hearing Scale (SSQ49). Results: As a group, participants showed significantly improved median SNR Loss thresholds when aided in a test condition that included spatial separation of speech and noise, with speech stimuli directed toward the worse ear and noise stimuli directed toward the better ear (diff. = −4.5; p < 0.001). Hearing aid use had a small, though statistically significant, negative impact on median SNR Loss thresholds, when speech and noise stimuli originated from the same 0° azimuth (diff. = 1.0; p = 0.018). This was also evidenced by the median WRS in sound field (diff. = −6.0; p = 0.006), which was lowered from 98% in the unaided state to 92% in the aided state. Results from the SSQ49 showed statistically significant improvement on all subsection means when participants were aided (p < 0.05), whereas results from the APHAB were generally found to be unremarkable between unaided and aided conditions as benefit was essentially equal to the 50th percentile of the normative data. At the close of the study, it was observed that only slightly more than half of all participants chose to continue use of a hearing aid after their participation. Conclusions: We observed that hearing aid use by individuals with USNHL can improve the SNR Loss associated with the interference of background noise, especially in situations when there is spatial separation of the stimuli and speech is directed toward the affected ear. In addition, hearing aid use by these individuals can provide subjective benefit, as evidenced by the APHAB and SSQ49 subjective benefit questionnaires.

This paper presents a new structure for hearing aids. Normally, the power consumption and user experience are contradictory. The proposed hearing aid structure mainly consists of three parts: the earpieces, the mobile computing platform, and the real-time speech-enhancement application. It can run complex algorithms without carrying out heavy calculations on the processors in the hearing aid. Thus, the binaural algorithm is utilized without being limited by complexity and power consumption to improve the user experience. Moreover, the speech-enhancement algorithm can be updated much more easily than in traditional built-in digital signal process hearing aids. A good level of user experience is achieved by combining the hearing aid and mobile computing platform with a 400-MHz transceiver; furthermore, the 400-MHz transceiver can reduce path loss around the body. The concept verification process showed that the overall usage of the central processing unit in the smartphone is around 16%, the signal-to-noise ratios show at least a 30% improvement in some environments, and the whole system delay is 8.8 ms. The presented objective and subjective results show significant improvements regarding user experience and usability brought about by the proposed structure.

Improving the signal-to-noise ratio (SNR) for individuals with hearing loss who are listening to speech in noise provides an obvious benefit. Although binaural hearing provides the greatest advantage over monaural hearing in noise, some individuals with symmetrical hearing loss choose to wear only one hearing aid. The present study tested the hypothesis that individuals with symmetrical hearing loss fit with one hearing aid would demonstrate improved speech recognition in background noise with increases in head turn. Fourteen individuals were fit monaurally with a Starkey Gemini in-the-ear (ITE) hearing aid with directional and omnidirectional microphone modes. Speech recognition performance in noise was tested using the audiovisual version of the Connected Speech Test (CST v.3). The test was administered in auditory-only conditions as well as with the addition of visual cues for each of three head angles: 0°, 20°, and 40°. Results indicated improvement in speech recognition performance with changes in head angle for the auditory-only presentation mode at the 20° and 40° head angles when compared to 0°. Improvement in speech recognition performance for the auditory + visual mode was noted for the 20° head angle when compared to 0°. Additionally, a decrement in speech recognition performance for the auditory + visual mode was noted for the 40° head angle when compared to 0°. These results support a speech recognition advantage for listeners fit with one ITE hearing aid listening in a close listener-to-speaker distance when they turn their head slightly in order to increase signal intensity.
