Abstract:
Introduction: Despite the advantages of using a hearing aid (HA), only 1 out of 5 individuals who could benefit from a (HA) actually use one (World Health Organization, 2012). If an individual does not use a HA then it may impact on their quality of life, as well as others around them (Chia et al., 2007). Therefore it is important to understand why individuals do not use HAs after obtaining them. To date, there has been no study that investigates the reasons for HA disuse in the New Zealand population. Methods: Two groups of adults with hearing impairment were recruited: HA users (N = 35) an

<p>Conventional hearing aids perform badly in environments with reverberation and noise. In this paper the use of microphone arrays as hearing aids to increase directivity and signal-to-noise ratio (SNR) in a noisy environment are evaluated. A portable microphone array prototype is constructed to test beamforming algorithms in a real environment. Delay and sum beamforming, sub-band beamforming and an experimental type of binaural beamforming is implemented in real-time using the digital signal processor ADSP-BF533. Results from testing showed that a four microphone array using sub-band beamfor

Abstract:
A new approach to the evaluation of hearing aid fitting has suggested that an adaptive frequency/gain characteristic is subjectively more beneficial for patients with precipitous high frequency hearing loss, listening to speech in the various quiet and noisy situations encountered in everyday life. The development and evaluation of such a hearing aid is described. Parameters for the operation of the adaptive response mechanism were determined experimentally by means of subjective listening tests using subjects with precipitous high frequency hearing loss.

Abstract:
Although hearing loss is among the most common chronic conditions in the U.S., many individuals never speak to a healthcare provider about it. Thus, evaluation and rehabilitation services remain underutilized. Even mild hearing loss may result in decreased quality of life, social isolation, and decreased selfsufficiency. The purpose of this study was to assess factors that influence hearing healthcare access and hearing aid acquisition by individuals in Southern Appalachia.

BACKGROUND: Population-based universal newborn hearing screening (UNHS) has been widely implemented in the developed world to ensure early detection of permanent hearing loss (HL) and improve the quality of speech and language outcomes of children with HL. Full-time hearing aid (HA) use is crucial for successful early intervention; most families face many challenges and uncertainties related to their child’s HA use in the early years after HA fitting. To our knowledge, there is limited information on HA use in children from Canadian settings, and there is no research using data logging records

This study investigates the listening environments of hearing aid users by employing the data logging capacity of their hearing aids. The idea that a hearing aid user's listening environments are important in prescribing desired hearing aid features has been discussed in the literature, however, investigation of listening environments has been limited in the past as it has relied mainly on subjective recordings. Data logging, the capacity of a hearing aid to continuously store information regarding time spent in different programs, listening environments, and microphone modes, is now available

This study concentrated on the problem of instability in a hearing aid system due to acoustic feedback. A mathematical model of feedback in the hearing aid system was developed. It was based on that of Egolf (1989. J. Acoust. Soc. Am. 85:1 pp 454-467), but included numerous feedback paths replacing the single path used by Egolf. A computer based analysis tool was designed and built that could measure feedback in the <I>in-situ</I> hearing aid.

Question: I've been fitting a lot of receiver-in-canal (RIC) products, and when I have a patient with good low-frequency hearing, I like to use the smaller gain receiver option because I worry about the larger gain receiver being noisier. Sometimes though, use of the smaller gain receiver makes it difficult to fit prescriptive targets for moderately-severe to severe high frequency hearing loss thresholds. Should I be concerned about larger receivers being noisier?

Abstract:
Hearing loss can significantly hinder an individual's ability to engage socially and, when left untreated, can lead to anxiety, depression, and even dementia. The most common type of hearing loss is sensor-neural hearing loss that is treated using hearing aids (HAs). However, a significant fraction of individuals that may benefit from using HA do not use them and, the satisfaction of those that do, is only around 60%. Today, we have only a limited understanding regarding the factors that contribute to the low adoption and satisfaction rates. This is a limitation of existing laboratory-based as

Industrial workers who have sustained hearing losses often wear hearing aids on the job in order to hear their co-worker's speech.

A maximum allowable level of 90 dBA averaged over a period of eight hours is considered safe.
