Congratulations to the following ASA members who were elected to Fellowship on 22 May 2015
Applied Physicist Robert G.W. Brown to Join American Institiute of Physics as CEO.
The Journal of the Acoustical Society of America (JASA) will publish a second special issue on Acoustic Metamaterials and is currently accepting manuscripts for a Special Issue entitled “Acoustic and Related Waves in Extraterrestrial Environments.”
The smearing effects of room reverberation can significantly impair the ability of cochlear implant (CI) listeners to understand speech. To ameliorate the effects of reverberation, current dereverberation algorithms focus on recovering the...
Whether crossing a busy intersection or attending a large dinner party, listeners sometimes need to attend to multiple spatially distributed sound sources or streams concurrently. How they achieve this is not clear—some studies suggest that listeners cannot truly simultaneously attend to separate streams, but instead combine attention switching with short-term memory to achieve something resembling divided attention. This paper presents two oddball...
In a recent paper [J. Acoust. Soc. Am. 133, 2224–2239 (2013)], Shera and Cooper report on the impulse response of the basilar membrane (BM) of a chinchilla, a waveform which shows repetitive bursts. They explain the bursts in terms of repeated coherent reflection at BM discontinuities and partial reflection at the stapes (“coherent reflection filtering”). Here the same waveform is examined in detail, highlighting features which indicate that the coherent reflection model, with calls for the same repetitive process to act on each successive burst, does not fully...
