A recently developed p‐version finite‐element program [Bagus et al., IBM Res. Div., Res. Rep., RJ 7733 (71598), October 1990; Carnevali et al., in preparation] was used to simulate the dynamic behavior of an ultrasonic bonding tool. The accuracy

Omnidirectional ambient noise levels were measured at two deep‐water locations in the northeastern Pacific Ocean. Hydrophones were positioned throughout the water column at depths ranging from about 200 m below the surface to about 150 m above the

A long vertical array of hydrophones was used to measure the vertical directionality of ambient noise in the ocean in the 10–50‐Hz frequency band. These measurements were made in deep water, 4300 m, at a site approximately 350 miles west of San D

F1 cutback has been demonstrated to be at least a contributing cue, and very possibly a major cue, for the perception of voicing contrasts. In an attempt to evaluate the feasibility of there existing an acoustic basis for the role of F1‐cutback cue

Our previous research described at the last Acoustical Society Meeting [Pastore et al., J. Acoust. Soc. Am. Suppl. 1 77, S27 (1985)] investigated duration effects in the perception of tone analogs to the delayed F1 onset cue for voicelessness. Two gr

Signals from SUS bombs were received at four hydrophones suspended in the deep ocean from the Research Platform FLIP. Using digital processing equipment and fast Fourier transform methods, energy‐flux spectral densities were determined for approxim

Several years ago, we discovered that the perception of an initial voiceless consonant “p” in a monaural CV syllable could be altered by a burst of noise roughly coincident (+/−50 ms) with the onset of the stop. These noise‐induced mispercept

Nearly three decades ago, Hirsh [J. Acoust. Soc. Am. 31, 759–761 (1959)] found that the threshold for identification of temporal order of onset is significantly longer than the threshold for detection of onset asynchrony, and proposed that the orde

Using a 532‐m‐long vertical array suspended near the sound channel axis, the vertical directionality of ambient noise in the 10–50‐Hz frequency band was measured at a location about 200 miles southwest of San Diego. The outputs from 20 hydrop

Acoustic propagation experiments at 104 Hz were made over Stoddard Seamount, about 800 km west of Los Angeles, to measure experimentally the interference of cw signals from a well‐surveyed seamount. The receiver station was the Research Platform FL
