Anatomical effects of impact noise
Hearing Research, 1994Four groups of binaural chinchillas were exposed to impact noise (B-duration = 200 ms) ranging from 119 dB to 137 dB peak equivalent SPL at repetition rates of 1/s or 4/s. The duration of exposure was adjusted so that each exposure consisted of equal acoustic energy. Animals were then sacrificed immediately, 24 h or 30 days after the exposure and their

Ergonomics, 1984
Abstract The effects and aftereffects of noise on human performance and affective state were investigated in two experiments. In the first, 48 undergraduate university students completed five paper-and-pencil performance tests in a noisy (85 dBA) and/or quiet (45 dBA) environment.

The Journal of the Acoustical Society of America, 1974
An overview of the effects of noise on people as can be determined from the scientific literature is presented. Only audible noise is considered and no attempt is made to describe the extent of the noise problem in terms of the number of people affected or in terms of social and economic costs.

Health effects of traffic noise
International Archives of Occupational and Environmental Health, 1980In 57 test persons having worked 1 day under traffic noise (Leq = 85 dB(A) and 1 day without noise (Leq < 50 dB(A), blood pressure and pulse frequency were measured at 1 h intervals and total urine was collected during working hours. Additionally, blood was sampled at the end of each working day.

FEW WOULD DENY THAT WE LIVE IN A NOISY WORLD. NOISE, whether a result of air traffic, crowded urban streets, personal stereos, or high-powered machinery, rifles, and shotguns, is one of America’s most widespread nuisances. Excessive noise disrupts sleep, produces stress, impairs communication, and, in high enough doses, causes significant noise-induced

Flicker Noise Effects in Noise Adding Radiometers
IEEE Transactions on Microwave Theory and Techniques, 2011This paper presents an analysis of noise adding radiometers that includes the effects of flicker, or 1/f, noise which often limits radiometer performance. The 1/f noise processes within the detector are affected by the modulation of the detector voltage as a result of the injected noise power and cause the overall 1/f noise to increase.

British Journal of Nursing, 1994
Excessive noise in health care settings can induce headaches, cause irritability, prolong wound healing and increase sensitivity to pain. Simple measures, such as wearing soft-soled shoes, closing doors to areas with excessive noise (the television or sluice rooms) and choosing equipment with quieter alarms, can improve patient outcomes and result in ...

Noise is an environmental stressor that is known to have physiological and psychological effects. The body responds to noise in the same way it responds to stress and overtime can impair health. Research clearly shows that hospital noise levels exceed noise level recommendations and has the potential to increase complications in patients.

Phase noise effects in QAM systems
Proceedings of 8th International Symposium on Personal, Indoor and Mobile Radio Communications - PIMRC '97, 2002The effects of oscillator phase noise on the performance of digital transmission systems employing QAM are investigated. The model used for the phase noise is a Wiener-Levy process which allows a moment characterization of the filtered phase noise.
