Leo Beranek celebrated his 100th Birthday on 15 September 2014

The work of this remarkable visionary has resulted in significant contributions to acoustics and to many other scientific disciplines.

Acoustics Today Summer Issue in now on-line...


Arthur Popper - This issue of Acoustics Today has an eclectic series of papers that includes consideration of climate change and bioacoustics, microphone arrays and the analysis of animal movement, the prehistoric origins and evolution of the flute, non-destructive testing of materials using acoustics, and effects of man-made sound on marine mammals.

Recognition of sentences containing periodic, 5-Hz, silent interruptions of differing duty cycles was assessed for three types of processed speech. Processing conditions employed different combinations of spectral resolution and the availability of fundamental frequency (F0) information, chosen to yield similar, below-ceiling performance for uninterrupted speech. Performance declined with decreasing duty cycle similarly for each processing condition, suggesting that, at least for certain forms of speech...

This study investigated whether recognition of time-compressed speech predicts recognition of natural fast-rate speech, and whether this relationship is influenced by listener age. High and low context sentences were presented to younger and older normal-hearing adults at a normal speech rate, naturally fast speech rate, and fast rate implemented by time compressing the normal-rate sentences. Recognition of time-compressed sentences over-estimated recognition of natural fast sentences for both groups, especially for older listeners. The findings suggest that older listeners are at a much...

There has been increasing attention in the literature to wearable acoustic recording devices, particularly to examine naturalistic speech in disordered and child populations. Recordings are typically analyzed using automatic procedures that critically depend on the reliability of the collected signal. This work describes the acoustic amplitude response characteristics and the possibility of...
