In spite of criticism, monosyllabic discrimination tests are widely employed for hearing aid selection. The current study was designed to investigate the following questions: (1) How reliable is aided speech discrimination of monosyllables in a background of white noise? (2) Can differences among hearing aids be reliably demonstrated by measuring intelligibility of monosyllables in a background of white noise? and (3) Do hearing aids interact with hearing loss? Twenty subjects with mild-moderate sensorineural hearing losses participated in two experimental sessions. Four hearing aids were evaluated using the NU-6 monosyllables in a background of white noise (s/n = +20 dB). Since the standard deviation of the test-retest differences was 6%, differences between aids were not considered significant unless they exceeded 12%. An interaction between subjects and hearing aids was found; that is, the best aid for one person was not the best for all. Measuring monosyllabic word intelligibility in a background of white noise does not reliably identify a single best aid. However, one or more inferior aids were consistently eliminated in 80% of the subjects.

Abstract Till about 15 years ago, the only choice of hearing improvement for moderate sensorineural hearing loss with severe speech discrimination defect was a hearing aid. It was only after Mr. Geoff Ball, an electronic engineer who was suffering from a similar defect, started thinking of an alternative to the conventional hearing aid that the Vibrant Soundbridge came into existence, and with the passage of time the indications for the use of the same have increased.

Hearing Aid Use

BACKGROUND Sensorineural hearing loss is the most common sensory deficit among older adults. Some of the psychosocial consequences of this condition include difficulty in understanding speech, depression, and social isolation. Studies have shown that older adults with hearing loss show some age-related cognitive decline. Hearing aids have been proven as successful interventions to alleviate sensorineural hearing loss. In addition to hearing aid use, the positive effects of auditory training—formal listening activities designed to optimize speech perception—are now being documented among adults with hearing loss who use hearing aids, especially new hearing aid users. Auditory training has also been shown to produce prolonged cognitive performance improvements. However, there is still little evidence to support the benefits of simultaneous hearing aid use and individualized face-to-face auditory training on cognitive performance in adults with hearing loss. OBJECTIVE This study will investigate whether using hearing aids for the first time will improve the impact of individualized face-to-face auditory training on cognition, depression, and social interaction for adults with sensorineural hearing loss. The rationale for this study is based on the hypothesis that, in adults with sensorineural hearing loss, using hearing aids for the first time in combination with individualized face-to-face auditory training will be more effective for improving cognition, depressive symptoms, and social interaction rather than auditory training on its own. METHODS This is a crossover trial targeting 40 men and women between 50 and 90 years of age with either mild or moderate symmetric sensorineural hearing loss. Consented, willing participants will be recruited from either an independent living accommodation or via a community database to undergo a 6-month intensive face-to-face auditory training program (active control). Participants will be assigned in random order to receive hearing aid (intervention) for either the first 3 or last 3 months of the 6-month auditory training program. Each participant will be tested at baseline, 3, and 6 months using a neuropsychological battery of computer-based cognitive assessments, together with a depression symptom instrument and a social interaction measure. The primary outcome will be cognitive performance with regard to spatial working memory. Secondary outcome measures include other cognition performance measures, depressive symptoms, social interaction, and hearing satisfaction. RESULTS Data analysis is currently under way and the first results are expected to be submitted for publication in June 2018. CONCLUSIONS Results from the study will inform strategies for aural rehabilitation, hearing aid delivery, and future hearing loss intervention trials.

A large number of personal amplifiers have recently become available commercially. These devices have not been classified as hearing aids by the FDA and are therefore not subject to the FDA rules and regulations governing the sales of hearing aid devices. In this investigation, several of these personal amplifiers were evaluated to determine potential benefits and problems for each device. The devices were evaluated electroacoustically and, also, subjectively by a group of adults with sensorineural hearing loss. The results of the electroacoustic evaluation revealed very sharply peaked frequency responses. The subjective evaluations revealed tremendous variability, with some preferences for power and low-frequency amplification. Clinical implications of these results and suggestions for further research are provided.

AbstractObjectives:This study aimed to report the bone-anchored hearing aid uptake and the reasons for their rejection by unilateral sensorineural deafness patients.Methods:A retrospective review of 90 consecutive unilateral sensorineural deafness patients referred to the Greater Manchester Bone-Anchored Hearing Aid Programme between September 2008 and August 2011 was performed.Results:In all, 79 (87.8 per cent) were deemed audiologically suitable: 24 (30.3 per cent) eventually had a bone-anchored hearing aid implanted and 55 (69.6 per cent) patients declined. Of those who declined, 26 (47.3 per cent) cited perceived limited benefits, 18 (32.7 per cent) cited reservations regarding surgery, 13 (23.6 per cent) preferred a wireless contralateral routing of sound device and 12 (21.8 per cent) cited cosmetic reasons. In all, 32 (40.5 per cent) suitable patients eventually chose the wireless contralateral routing of sound device.Conclusion:The uptake rate was 30 per cent for audiologically suitable patients. Almost half of suitable patients did not perceive a sufficient benefit to proceed to device implantation and a significant proportion rejected it. It is therefore important that clinicians do not to rush to implant all unilateral sensorineural hearing loss patients with a bone-anchored hearing aid.

Conductive Component

Background: Hearing aid prescriptive recommendations for hearing losses having a conductive component have received less clinical and research interest than for losses of a sensorineural nature; as a result, much variation remains among current prescriptive methods in their recommendations for conductive and mixed hearing losses (Johnson and Dillon, 2011). Purpose: The primary intent of this brief clinical note is to demonstrate differences between two algebraically equivalent expressions of hearing loss, which have been approaches used historically to generate a prescription for hearing losses with a conductive component. When air and bone conduction thresholds are entered into hearing aid prescriptions designed for nonlinear hearing aids, it was hypothesized that that two expressions would not yield equivalent amounts of prescribed insertion gain and output. These differences are examined for their impact on the maximum power output (MPO) requirements of the hearing aid. Subsequently, the MPO capabilities of two common behind-the-ear (BTE) receiver placement alternatives, receiver-in-aid (RIA) and receiver-in-canal (RIC), are examined. Study Samples: The two expressions of hearing losses examined were the 25% ABG + AC approach and the 75% ABG + BC approach, where ABG refers to air-bone gap, AC refers to air-conduction threshold, and BC refers to bone-conduction threshold. Example hearing loss cases with a conductive component are sampled for calculations. The MPO capabilities of the BTE receiver placements in commercially-available products were obtained from hearing aids on the U.S. federal purchasing contract. Results: Prescribed gain and the required MPO differs markedly between the two approaches. The 75% ABG + BC approach prescribes a compression ratio that is reflective of the amount of sensorineural hearing loss. Not all hearing aids will have the MPO capabilities to support the output requirements for fitting hearing losses with a large conductive component particularly when combined with significant sensorineural hearing loss. Generally, current RIA BTE products have greater output capabilities than RIC BTE products. Conclusions: The 75% ABG + BC approach is more appropriate than the 25% ABG + AC approach because the latter approach inappropriately uses AC thresholds as the basis for determining the compression ratio. That is, for hearing losses with a conductive component, the AC thresholds are not a measure of sensorineural hearing loss and cannot serve as the basis for determining the amount of desired compression. The Australian National Acoustic Laboratories has been using the 75% ABG + BC approach in lieu of the 25% ABG + AC approach since its release of the National Acoustic Laboratories—Non-linear 1 (NAL-NL1) prescriptive method in 1999. Future research may examine whether individuals with conductive hearing loss benefit or prefer more than 75% restoration of the conductive component provided adequate MPO capabilities to support such restoration.

AbstractPersons with clinically significant tinnitus also may have mild sensorineural hearing loss (MSNHL). The purpose of this study was to describe patients with tinnitus and MSNHL and factors predicting hearing-aid uptake (HAU). We conducted a retrospective chart review with regression modeling of patients presenting to a specialty tinnitus clinic over a 2.5-year period. Stepwise logistic regression on data from patient charts was conducted. Of 133 patients seen, two-thirds had MSNHL (95% confidence interval [CI]: 58.9–75.0; mean age = 53.4 years; standard deviation = 14.5); approximately 50% had severe-to-catastrophic tinnitus. Logistic regression indicated that four-frequency pure-tone average (FFPTA; left) (β = 0.3899, χ 2 = 10.96, degrees of freedom [DF] = 1, p = 0.0009) and age (β = 0.1273, χ 2 = 4.86, DF = 1, p = 0.0274) were positively associated with HAU; tinnitus severity was inversely related (β = − 1.0533, χ 2 = 4.24, DF = 1, p = 0.0395). Adjusting for key variables, odds of receiving hearing aids was 1.14 (95% CI: 1.01–1.27) times higher with every year increase in age, 1.48 (95% CI: 1.17–1.86) times higher per one point increase in FFPTA (left), and 0.35 (95% CI: 0.13–0.95) times less per one point increase in tinnitus severity score. Reasons why HAU was not high for this special sample of young adults with severe tinnitus and MSNHL are discussed; hearing aid treatment requires extensive counseling and follow-up for this population.

Hearing impairment in the elderly is usually treated with conventional hearing aids; however, a large number of older people do not achieve sufficient speech recognition with hearing aids. The aim of the study was to describe speech perception with hearing aids in comparison to pure-tone hearing loss and maximum speech recognition scores for phonemically balanced words. Data from 392 hearing aid users with different degrees of hearing loss were evaluated retrospectively. In particular, pure-tone thresholds, the maximum monosyllabic word score, and the monosyllabic word score in quiet at conversational level with a hearing aid were analysed. The results showed that speech perception scores decline with increasing age. Even when corrected for pure-tone hearing loss, a significant decline in speech recognition scores after the age of 80 years was observed. Regarding the maximum monosyllabic word score, the effect is smaller but still observable; thus, speech recognition with hearing aids is significantly lower for older subjects. This can be attributed partially to the reduction of the information-carrying capacity in this group.

We prospectively evaluated the surgical, audiologic, and quality-of-life outcomes in 5 patients—2 men and 3 women, aged 22 to 64 years (mean: 41.8)—who were implanted with the Sophono Alpha 2 MPO Processor. The indications for implantation of this bone-conduction device included recurrent ear canal infections with hearing aids (n = 3), single-sided deafness (n = 1), and patient preference in view of difficulty using a conventional hearing aid (n = 1). In addition to the patient with single-sided deafness, 3 patients had a bilateral mixed hearing loss and 1 had a bilateral conductive hearing loss. Outcomes measures included surgical complications, functional gain (FG), speech discrimination in quiet and noise, and patient satisfaction as determined by the Glasgow Benefit Inventory (GBI) and the Entific Medical Systems bone-anchored hearing aid questionnaire (BAQ). The only postsurgical complication noted was a minor skin reaction and pain in 1 patient that resolved with conservative management. In the 3 patients with the mixed hearing loss, the mean FG was 13.3, 20.0, 11.7, and 11.7 dB at 0.5, 1, 2, and 4 kHz, respectively; in the patient with the bilateral conductive hearing loss, the FG was 10, 25, 10, and 15 dB at the same frequencies. Speech discrimination scores with the Sophono device were comparable to those seen with conventional hearing aids. After implantation, all 5 patients experienced a positive quality-of-life outcome according to the GBI, although 1 of them had only a marginal improvement. On follow-up, all patients reported that they remained satisfied with their implant and that they used their device all day long. We conclude that the Sophono bone-conduction system is a safe and effective option that should be considered for patients with a mixed or conductive hearing loss who are unable to use a conventional hearing aid, as well as for those with single-sided deafness.

Two cases are presented exhibiting temporary increases in sensorineural hearing loss following hearing aid use. Data suggesting this correlation are shown. There were no contributing middle ear problems during the period surveyed. The most significant changes in hearing thresholds were at frequencies 1000 and 2000 Hz. The use of different hearing aids, with decreased maximum power outputs, was not found to have similar effects on hearing threshold levels. A scheduling regime is recommended for introducing any new hearing aid to a child.
