Evaluation of noise susceptibility: Effects of noise exposure on acoustic reflex
International Archives of Occupational and Environmental Health, 1983The threshold of acoustic reflex (AR) was measured in workers exposed to occupational noise. White noise (WN), and pure tones of 1 and 4 kHz were selected as activating stimuli for AR. The results were compared with the thresholds of AR (ART) in the normal group (Group C) reported by the authors previously. To examine in relation between noise exposure

Optimization of a noise reduction preprocessing in an acoustic echo and noise controller
1996 IEEE International Conference on Acoustics, Speech, and Signal Processing Conference Proceedings, 2002In hands-free communications, the speech signal to be transmitted is disturbed by ambient noise and acoustic echo. So, processing to reduce these disturbances must be performed before transmission. Classical solutions are cascaded structures where the acoustic echo canceller precedes or follows the noise reduction system.

Overview of a university course on acoustics and noise
The Journal of the Acoustical Society of America, 2012The Bachelor of Mechanical Engineering at the University of New South Wales in Sydney, Australia is a four year degree program. In their fourth and final year, students can choose from a range of technical elective courses, one of those being in acoustics.

Acoustic noise interferometry uses long time series recordings of ambient and shipping noise, which are concurrently captured at two locations, to measure the acoustic Green’s function. With this technique, each hydrophone becomes a virtual acoustic transceiver—a combination of a source and a receiver—which can be used for passive acoustic remote ...

Acoustics of fish shelters: Background noise and signal-to-noise ratio
The Journal of the Acoustical Society of America, 2014Fish shelters (flat stones, shells, artificial covers, etc., with a hollow beneath) increase the sound pressure levels of low frequency sounds (<150 Hz) outside the nest cavity, see Lugli [(2012). J. Acoust. Soc. Am. 132, 3512–3524]. Since some calling males only produce sound when a female is inside the shelter, this study examines the effect ...

A Tempestuous Noise: on the Acoustics and Vocalics of Storms
2014St James’s Day 1609 witnessed a big noise in the Bermudas, an almighty North Atlantic commotion provoked by the storm that wrecked the Sea Venture, flagship of the Virginia Company, the enterprise chartered three years earlier by St James’s namesake King James I.
