On detectable and meaningful speech-intelligibility benefits (2016)
Journal Article
Whitmer, W. M., McShefferty, D., & Akeroyd, M. A. (in press). On detectable and meaningful speech-intelligibility benefits. Advances in Experimental Medicine and Biology, 894, https://doi.org/10.1007/978-3-319-25474-6_47

The most important parameter that affects the ability to hear and understand speech in the presence of background noise is the signal-to-noise ratio (SNR). Despite decades of research in speech intelligibility, it is not currently known how much impr... Read More about On detectable and meaningful speech-intelligibility benefits.

The just meaningful difference in speech-to-noise ratio (2016)
Journal Article
McShefferty, D., Whitmer, W. M., & Akeroyd, M. A. (2016). The just meaningful difference in speech-to-noise ratio. Trends in Hearing, 20, https://doi.org/10.1177/2331216515626570

The speech-to-noise ratio (SNR) in an environment plays a vital role in speech communication for both normal-hearing (NH) and hearing-impaired (HI) listeners. While hearing-assistance devices attempt to deliver as favorable an SNR as possible, there... Read More about The just meaningful difference in speech-to-noise ratio.

Biomimetic direction of arrival estimation for resolving front-back confusions in hearing aids (2015)
Journal Article
Archer-Boyd, A. W., Whitmer, W. M., Brimijoin, W. O., & Soraghan, J. J. (2015). Biomimetic direction of arrival estimation for resolving front-back confusions in hearing aids. Journal of the Acoustical Society of America, 137(5), doi:10.1121/1.4918297

Sound sources at the same angle in front or behind a two-microphone array (e.g., bilateral hearing aids) produce the same time delay and two estimates for the direction of arrival: A front-back confusion. The auditory system can resolve this issue us... Read More about Biomimetic direction of arrival estimation for resolving front-back confusions in hearing aids.

The just-noticeable difference in speech-to-noise ratio (2015)
Journal Article
McShefferty, D., Whitmer, W. M., & Akeroyd, M. A. (2015). The just-noticeable difference in speech-to-noise ratio. Trends in Hearing, 19(1), https://doi.org/10.1177/2331216515572316

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)....

The effect of hearing aid microphone mode on performance in an auditory orienting task (2014)
Journal Article
Brimijoin, W. O., Whitmer, W. M., McShefferty, D., & Akeroyd, M. A. (2014). The effect of hearing aid microphone mode on performance in an auditory orienting task. Ear and Hearing, 35(5), Article e204-e212. https://doi.org/10.1097/AUD.0000000000000053

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.

The perception of apparent auditory source width in hearing-impaired adults (2014)
Journal Article
Whitmer, W. M., Seeber, B. U., & Akeroyd, M. A. (2014). The perception of apparent auditory source width in hearing-impaired adults. Nature Energy, 135(6), https://doi.org/10.1121/1.4875575

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...

Proposed norms for the Glasgow hearing-aid benefit profile (Ghabp) questionnaire (2014)
Journal Article
Whitmer, W. M., Howell, P., & Akeroyd, M. A. (2014). Proposed norms for the Glasgow hearing-aid benefit profile (Ghabp) questionnaire. International Journal of Audiology, 53(5), 345-351. https://doi.org/10.3109/14992027.2013.876110

Objective: To form a normative set of responses to the GHABP questionnaire from a large regional dataset. Design: Participants were asked to rate their hearing disability, handicap, hearing-aid (HA) use, HA benefit, HA satisfaction, and residual (aid...
