Speaker: Dr. Alan Archer-Boyd

Alan Archer-Boyd is a post-doc at the MRC Cognition and Brain Sciences Unit. Since joining the CBU in 2015 he has developed the STRIPES test for assessing cochlear-implant (CI) listeners’ spectro-temporal processing performance. He is currently investigating the effect of head movement and dynamic-range compression on CI listeners’ perception of sound level. Previously he was a post-doc on the ICANHEAR project at the Institute for Communication Acoustics, Ruhr-Universität Bochum  (Bochum, Germany), and a Ph.D. student at the MRC/CSO Institute of Hearing Research – Scottish Section (Glasgow, UK). His main research interests are spatial hearing, audio signal processing, and head movement in normal-hearing and hearing impaired listeners.

Subject: “Hearing and head movement: auditory externalization, conversations, and hearing prostheses signal processing”.

The auditory environment is almost constantly moving, due to both listener and sound source motion. Research has increased in recent years on the effects of motion, and in particular head movement, on auditory perception. This talk will cover a wide-range of areas where head movement has been studied with respect to listening, including its effects on the externalization of sounds, analysis of conversations in different acoustic scenarios, and listener orienting behaviour in noisy environments. The interaction between head movement and hearing device signal processing will be discussed, including the use of head-movement information to improve the performance of the devices.
