BACKGROUND Although the benefits of hearing aids are generally recognized for soft- and conversational-level sounds, most studies have reported negative benefits (i.e., poorer aided than unaided performance) at high noise inputs. Advances in digital signal processing such as compression, noise reduction, and directional microphone could improve speech perception at high input levels. This could alter our view on the efficacy of hearing aids in loud, noisy situations. PURPOSE The current study… 
Effect of audibility on better-ear glimpsing as a function of frequency in normal-hearing and hearing-impaired listeners.
The spatial benefit provided by BEG and SRTs improved consistently with increasing sensation level, but was limited in the HI listeners by loudness discomfort, which helps to understand the hearing aid gain that is required to maximize the spatial Benefit provided by ILDs as a function of frequency.
Continued search for better prediction of aided speech understanding in multi-talker environments.
Analysis of psychometric functions showed that enhancement of the target speech fidelity through improvement of signal-to-noise ratio had a larger impact on listeners' performance in the phonetic condition than in the semantic condition, demonstrating the importance of incorporating naturalistic elements in the simulation of multi-talker listening for assessing the benefits of intervention in communication success.
A Comparison of Environment Classification Among Premium Hearing Instruments
Comparisons of classification schemes among five premium hearing instruments in a wide range of acoustic scenes including those that vary in signal-to-noise ratio and overall level revealed a variety of similarities and differences among the five devices and the human subjects.
Basis of Effortless Hearing : Capturing the Natural Nuances
  • 2015
Numerous studies were available in the last few years to support a strong relationship between cognition and hearing.1 What is noteworthy from these studies is that the type of amplified sounds could

This scenario is quite common when hearing aid users are listening to music or in the presence of loud sounds or noises, since both scenarios have peaks exceeding 100 dB SPL. Examples of such

The MarkeTrak VIII (2009) report on 25-year trends in the hearing aid industry revealed that only 1 in 4 people with a hearing loss wear hearing aids. Among those with a hearing impairment, only 1 in
Association of pigmentation and melanocortin-one receptor genotype with susceptibility to noise-induced hearing loss in college-aged music students
No association was found between noise-induced hearing loss and pigmentation and the single nucleotide polymorphisms in the melanocortin-one receptor gene, and despite this, a trend of increased thresholds in individuals with pigmentation indicating decreased levels of eumelanin was able to be detected.


The effect of a hearing aid on the speech-reception threshold of hearing-impaired listeners in quiet and in noise.
It is shown that, generally, current hearing aids do not improve speech intelligibility in noise beyond, roughly, 60 dBA, and that a model of SRT as a function of noise level, developed by Plomp, gives a good description of the SRT values measured.
Intelligibility of speech in noise at high presentation levels: Effects of hearing loss and frequency region
Three experiments are reported which examined how high presentation levels influence speech recognition for highand lowfrequency stimuli in noise. Normally hearing (NH) and hearing-impaired (HI)
Hearing aid benefit in everyday environments.
Benefit was significantly related to speech reception threshold in the living-room environment, however, in the less favorable environments, benefit and hearing loss were not related despite the fact that benefit varied considerably across subjects.
Improving hearing aid performance in noise: Challenges and strategies
Achieving this entails not only improving speech understanding in noise, but also increasing ease of listening and comfort and reducing listening strain and potential risk of additional hearing loss from excessive noise exposure.
Effect of maximum power output and noise reduction on speech recognition in noise.
An MPO that was 10 dB lower than the default could negatively affect the signal-to-noise ratio (SNR) of the listening environment, however, NR could compensate for the degradation in SNR.
Speech Recognition Performance of Patients with Sensorineural Hearing Loss Under Unaided and Aided Conditions Using Linear and Compression Hearing Aids
Objectives This study compared speech recognition performance on the Northwestern University Auditory Test No. 6 (NU-6) and the Connected Speech Test (CST) for three hearing aid circuits (peak
Noise‐management algorithm may improve speech intelligibility in noise
It is suggested that hearing-impaired persons whose hearing aids have noise reduction may be less affected by high-output sound pressure levels, less stressed, and less distracted in noisy situations, and may be more likely to attend to the sound sources and wear their hearing aids longer than if they lacked this feature.
Monosyllabic word recognition at higher-than-normal speech and noise levels.
Speech intelligibility in noise decreases when speech levels exceed 69 dB SPL and the S/N ratio remains constant, and the effective dynamic range of speech may be larger than the commonly assumed value of 30 dB.
Subjective and objective evaluation of noise management algorithms.
The results suggest that the directional microphone and the SII-based noise reduction algorithm may improve the SNR of the listening environments, and both the HINT and the ANL may be used to study their benefits.
