Objectives:
Current hearing aids have a limited bandwidth, which limits the intelligibility and quality of their output, and inhibits their uptake. Recent advances in signal processing, as well as novel methods of transduction, allow for a greater...

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.

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)....
