The Acoustical Society of America (ASA) is again facilitating remote participation by members in some technical sessions and committee meetings to be held at the upcoming Salt Lake City meeting.
West Barnstable (MA), April 19, 2016 — Elizabeth A. Bury will join the Journal of the Acoustical Society of America (JASA) as Managing Editor on May 2, 2016.
At its bi-annual meeting in Jacksonville Florida this week, the Acoustical Society of America approved the Strategic Leadership for the Future Plan.
Previous research suggests that many speechsounds are perceived in discrete categorical units. For example, perceivers typically identify acoustic stimuli from a continuum that ranges from one syllable to another (e.g., /va/-to-/ba/) exclusively as one syllable with a sharp change in which syllable the stimuli are identified as in the middle of the continuum. Further, pairs of continuum stimuli are typically easier to...
The Lombard Effect is an involuntary tendency to raise the level of the voice with an increase in the background noise level. The aim of this study was to determine whether there is a starting point of the Lombard Effect in terms of background noise level (Ln).Twenty subjects were instructed to read a passage with the goal of being understood by a listener at 2m. A...
The audio quality of flat panel loudspeakers may be improved dramatically by selectively driving specific panel modes using an array of force actuators distributed on the panel surface. An optimal actuator array layout will maximize the energy coupling between the actuators and selected panel modes, while simultaneously eliminating modal crosstalk within the operating frequency band. We present results for optimal force...
