Hearing In Noise

Purpose Directional microphone systems are typically used to improve hearing aid users' understanding of speech in noise. However, directional microphones also increase internal hearing aid noise. The purpose of this study was to investigate how varying directional microphone bandwidth affected listening preference and speech-in-noise performance. Method Ten participants with normal hearing and 10 participants with hearing impairment compared internal noise levels between hearing aid memories with 4 different microphone modes: omnidirectional, full directional, high-frequency directionality with directional processing above 900 Hz, and high-frequency directionality with directional processing above 2000 Hz. Speech-in-noise performance was measured with each memory for the participants with hearing impairment. Results Participants with normal hearing preferred memories with less directional bandwidth. Participants with hearing impairment also tended to prefer the memories with less directional bandwidth. However, the majority of participants with hearing impairment did not indicate a preference between omnidirectional and directional above 2000 Hz memories. Average hearing-in-noise performance improved with increasing directional bandwidth. Conclusions Most participants preferred memories with less directional bandwidth in quiet. Participants with hearing impairment indicated no difference in preference between directional above 2000 Hz and the omnidirectional memories. Speech recognition in noise performance improved with increasing directional bandwidth.

Congenital Aural Atresia

Congenital aural atresia is the failure of development of the external auditory canal. It usually occurs in conjunction with microtia, which is the malformation of the auricle due to a failure of development of the external ear. Aural atresia, with or without microtia, may significantly affect the hearing and social life of the patients. It is important for every medical practitioner to be aware of the possible treatment options for hearing rehabilitation in this group of patients. In the era of modern technology, new choices, including Bone-Anchored Hearing Aid (BAHA) (Cochlear Ltd. and Oticon Medical), Vibrant Soundbridge (VSB) (MED-EL, Innsbruck, Austria), and Bonebridge system (BB) (MED-EL, Innsbruck, Austria), provide high-end alternatives to traditional Bone Conduction Hearing Aid and Auditory Canal Reconstruction. All these options have advantages and disadvantages, and they are appropriate for different patients and/or at different ages. This paper aims to provide an overview of the management of hearing rehabilitation in congenital aural atresia patients and a discussion of each treatment option.

AbstractThere is a growing body of evidence demonstrating self-reported hearing difficulties (HD; i.e., substantial difficulty in understanding speech in complex listening situations) in adults with normal pure-tone sensitivity. Anecdotally, some audiologists have tried personal mild-gain amplification as a treatment option for adults with HD. In 2008, Kuk and colleagues reported positive results of a mild-gain hearing aid trial for children with auditory processing disorders. To date, however, there have been no studies investigating the benefit of mild-gain amplification to treat HD in adults with normal audiograms.The effectiveness of a four-week trial with mild-gain amplification for adults with self-reported HD and clinically normal hearing sensitivity was investigated.Two participant groups with normal pure-tone audiograms (thresholds ≤20 dB HL 250–8000 Hz) were recruited to study the effects of self-reported HD on hearing handicap, self-perceived auditory processing difficulties, and performance on a speech-in-noise task. Furthermore, the benefit of mild-gain amplification was examined after a four-week hearing aid trial on self-perceived hearing handicap and auditory processing difficulties, and performance on an aided speech-in-noise task. Effects were analyzed using a mixed-model repeated measures analysis of variance. Posthoc analyses were performed for each significant main effect.Thirty-nine participants participated in two groups. Twenty normal hearing adults (19–27 yr) without complaints of HD were recruited as a control group. Nineteen normal hearing adults (18–58 yr) with self-reported HD were recruited for the mild-gain hearing aid trial.Subjective complaints of HD were assessed with two questionnaires (the Hearing Handicap Inventory for Adults [HHIA] and the Auditory Processing Questionnaire [APQ]) and an auditory processing test battery (SCAN:3-A, dichotic digit recognition, gaps-in-noise test, and the 500-Hz masking level difference). Speech-in-noise abilities were assessed before and after hearing aid trial using the Revised Speech Perception in Noise Test (R-SPIN) at multiple signal-to-noise ratios. Hearing aid use and impressions during the hearing aid trial were recorded.Results demonstrated that participants with HD perceived significantly greater hearing handicap (HHIA) and greater self-perceived auditory processing difficulties (APQ) than the control group. Participants with HD performed significantly poorer on the R-SPIN relative to controls, especially for low-predictability items. Results of the hearing aid trial for participants with HD revealed significant improvements in hearing handicap, self-perceived auditory processing difficulties, and speech-in-noise performance relative to prehearing aid trial measures. The hearing aids were well tolerated by the majority of participants with HD , with most of them wearing the hearing aids an average of 1–4 h per day.The results from the present study suggest that adults who present with complaints of HD even in the presence of normal hearing sensitivity represent a unique population that warrants further evaluation beyond the standard hearing test. Furthermore, results from the hearing aid trial suggest that mild-gain amplification is a viable treatment option for at least some individuals with HD.

Bone Conduction Hearing Aid

Hearing aid implant is not suitable for little children with congenital aural atresia because their skulls are still growing. Since the critical period of speech and language development is during the first three years of life, the child has to be exposed to verbal stimulation as early as possible. The purpose of this study is to develop an external bone-conduction hearing aid for a newborn child. A headband or spectacle can be used to keep the hearing aid in position. To improve the design of the hearing aid vibrator, finite element analysis was applied to analyze the structure factors that affect the performance of the vibrator. The vibrator and head were simulated as a whole system to acquire more accurate estimation of the spectral response of the bone-conduction hearing aid. The measurement on artificial mastoid shows the vibrator has a wide working range from 200 to 4000 Hz, which covers the most crucial acoustic frequency range for speech recognition. The test of bone conduction hearing aid on adult subjects shows comparative performances with a commercial device. This miniature and low-price bone conduction hearing aid will help the specific group of hearing impaired kids to begin the required early intervention therapy.

Hearing Problems

Purpose The aim of the study was to assess how the use of a mild-gain hearing aid can affect hearing handicap, motivation, and attitudes toward hearing aids for middle-age, normal-hearing adults who do and do not self-report trouble hearing in background noise. Method A total of 20 participants (45–60 years of age) with clinically normal-hearing thresholds (< 25 dB HL) were enrolled in this study. Ten self-reported difficulty hearing in background noise, and 10 did not self-report difficulty hearing in background noise. All participants were fit with mild-gain hearing aids, bilaterally, and were asked to wear them for 2 weeks. Hearing handicap, attitudes toward hearing aids and hearing loss, and motivation to address hearing problems were evaluated before and after participants wore the hearing aids. Participants were also asked if they would consider purchasing a hearing aid before and after 2 weeks of hearing aid use. Results After wearing the hearing aids for 2 weeks, hearing handicap scores decreased for the participants who self-reported difficulty hearing in background noise. No changes in hearing handicap scores were observed for the participants who did not self-report trouble hearing in background noise. The participants who self-reported difficulty hearing in background noise also reported greater personal distress from their hearing problems, were more motivated to address their hearing problems, and had higher levels of hearing handicap compared to the participants who did not self-report trouble hearing in background noise. Only 20% (2/10) of the participants who self-reported trouble hearing in background noise reported that they would consider purchasing a hearing aid after 2 weeks of hearing aid use. Conclusions The use of mild-gain hearing aids has the potential to reduce hearing handicap for normal-hearing, middle-age adults who self-report difficulty hearing in background noise. However, this may not be the most appropriate treatment option for their current hearing problems given that only 20% of these participants would consider purchasing a hearing aid after wearing hearing aids for 2 weeks.
