The work of this remarkable visionary has resulted in significant contributions to acoustics and to many other scientific disciplines.
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.
James F. (Jim) Lynch has been selected to be the next Editor-in-Chief of the Acoustical Society of America (ASA). He began his service with the ASA as Editor-in-Chief Designate on 15 August 2014 and will assume the title of Editor-in-Chief on 1 November 2014.
This paper presents an application to validate an acoustic signal characterization scheme for ocean acoustic tomography and geoacoustic inversions proposed by Taroudakis, Tzagkarakis, and Tsakalides [J. Acoust. Soc. Am. 119, 1396–1405 (2006)] using data from an experiment at sea. The data were collected during the Shallow...
This study explored gender-related differences in affricates' place of articulation of young Seoul Korean speakers. Word-initial and medial affricates before /a/ and /i/ collected from 42 adult Seoul speakers were compared with alveolar and palatalized fricatives in the same vowel conditions by examining spectral peak frequencies of the frication part of the consonants. Results showed evidence of gender differences in the...
Startling auditory stimulus (SAS) can trigger rapid release of pre-planned movement sequences and can effect a physiological perturbation of pitch level. An SAS-based paradigm was used to investigate planning of pitch profiles in English and Taiwanese Mandarin. Results show that startle-elicited pitch level is elevated, whereas pitch contours are preserved. These results support the view that pitch contours are pre-specified in speech plans, while absolute pitch level is not.
