A number of assessment tools exist to evaluate the impact of hearing loss, with little consensus among researchers as to either preference or psychometric adequacy. The item content of hearing loss assessment tools should seek to capture the impact o...

INTRODUCTION: Hearing loss is a highly prevalent condition that affects around 1 in 6 people in the UK alone. This number is predicted to rise by the year 2031 to a staggering 14.5 million people due to the ageing population of the UK. Currently, th...

The effects of hearing impairment, age, and hearing aids on the use of self motion for determining front/back location (2016)
Journal Article
Brimijoin, W. O., & Akeroyd, M. A. (2016). The effects of hearing impairment, age, and hearing aids on the use of self motion for determining front/back location. Journal of the American Academy of Audiology, 27(7), https://doi.org/10.3766/jaaa.15101

Background: There are two cues that listeners use to disambiguate the front/back location of a sound source: high-frequency spectral cues associated with the head and pinnae, and self-motion‐related binaural cues. The use of these cues can be comp... Read More about The effects of hearing impairment, age, and hearing aids on the use of self motion for determining front/back location.

The just-noticeable difference in speech-to-noise ratio (2015)
Journal Article

Just-noticeable differences (JNDs) have been measured for various features of sounds, but despite its importance to communication, there is no benchmark for what is a just-noticeable—and possibly meaningful—difference in speech-to-noise ratio (SNR)....

An overview of the major phenomena of the localization of sound sources by normal-hearing, hearing-impaired, and aided listeners (2014)
Journal Article

Localizing a sound source requires the auditory system to determine its direction and its distance. In general, hearing-impaired listeners do less well in experiments measuring localization performance than normal-hearing listeners, and hearing aids...

The moving minimum audible angle is smaller during self motion than during source motion (2014)
Journal Article

We are rarely perfectly still: our heads rotate in three axes and move in three dimensions, constantly varying the spectral and binaural cues at the ear drums. In spite of this motion, static sound sources in the world are typically perceived as stab...

OBJECTIVES: Although directional microphones on a hearing aid provide a signal-to-noise ratio benefit in a noisy background, the amount of benefit is dependent on how close the signal of interest is to the front of the user. It is assumed that whe... Read More about The effect of hearing aid microphone mode on performance in an auditory orienting task.

Although many studies have looked at the effects of different listening conditions on the intelligibility of speech, their analyses have often concentrated on changes to a single value on the psychometric function, namely, the threshold. Far less com... Read More about Variations in the slope of the psychometric functions for speech intelligibility: a systematic survey.

In a previous study [Whitmer, Seeber and Akeroyd, J. Acoust. Soc. Am. 132, 369-379 (2012)], it was demonstrated that older hearing-impaired (HI) listeners produced visual sketches of headphone-presented noises that were insensitive to changes in inte...
