A comprehensive series of underwater psychoacoustic tests were conducted with captive manatees to measure their hearing abilities under varying acoustic conditions. Forced‐choice paradigms with either a staircase, or method of constants, psychometric were used to define...

Cubick and Dau [(2016). Acta Acust. Acust. 102, 547-557] showed that speech reception thresholds (SRTs) in noise, obtained with normal-hearing listeners, were significantly higher with hearing aids (HAs) than without. Some listeners reported a change in their spatial pe...

With the increased need for persons with specialized education in Acoustics, it is timely to discuss a variety of problems related to education. The educators, representatives of the industry, research, consulting and other areas of acoustic employment will have the opp...

A real‐time ultrasonic imaging system has been developed to visualize dynamic motions of the tongue during continuous speech. Lingual motion configurations are displayed and recorded synchronously with the speech signal, time in milliseconds, and frontal and lateral vie...

Phenomenological models reproducing the elasticity and acoustic properties of geomaterials and materials with damage have been successfully developed. These models yield macroscopic stress–strain constitutive equations featuring hysteresis with end-point memory, and pre...

Sonochemistry is able to give information about the extreme conditions prevailing inside collapsing bubbles. However, this information is obtained only when the experimental data correspond to primary chemical steps taking place in the gas phase inside the bubbles. This...

It is convenient to use dimensional analysis in investigating nonlinear effects in woodwind instrument air columns. One dimensionless quantity characterizing the flow is the Reynolds number. There is both a time‐varying particle velocity as well as a time‐independent st...

When listening to speech in a fluctuating background, subjects with normal hearing can operate at a higher signal‐to‐noise ratio (SNR) by taking advantage of momentary decreases in background level. Subjects with even a mild hearing loss are less able to do so. This was...

The aging process is known to affect the processing of somatosensory information. For example, a number of recent studies have shown that detection thresholds for vibrotactile stimuli are elevated at low and high frequencies in elderly individuals, as compared to compar...

A piezoelectric oscillator using zinc oxide as a piezoelectric plate which eliminates unwanted resonance called inharmonic overtone by optimizing ratio Le/H of driving electrode length Le to oscillator thickness H. Ratio Le/H is set between 4 and 100 in the piezoelectri...
