Noise reduction system for rooms - uses loudspeakers emitting white noise to prevent noise build-upThe loud-speakers are placed at window height up a wall, with their axes vertical. Each loudspeaker rim is fixed to the edge of an orifice in a square or rectangular plate, two sides of which...
Chart: Typical values of NRC (noise reduction coefficient) for some common materials. Green (top) indicates most absorbent; red (bottom) most reflective. Note that NRC values do vary substantially according to whether materials are, for example, painted or coated with other materials. Even so, ...
DURING the last two years, progress has been made in the problem of noise reduction, especially in sound-proofing rooms against the transmission of external noise. In Engineering of October 25 the allied problem is described of sound-proofing rooms by using Accousti-Celotex tiles of sugar-cane ...
noise can affect productivity, customer satisfaction, and overall success. Whether it’s sound that’s finding its way between rooms, lingering within one room, or traveling between floors to the space below, we provide noise reduction solutions that make sound complaints and inconvenience a thing ...
Although disturbing environments are a long-established problem, efforts are currently being made to encourage the reduction of noise levels and interruptions in hospitals. Most notably have been the implementation of quiet time interventions. A quiet time often consists of, but is not limited to, ...
A microphone array with adaptive post-filtering for noise reduction in reverberant rooms The author presents a self-adapting noise reduction system which is based on a four-microphone array combined with an adaptive postfiltering scheme. Noise ... R Zelinski - International Conference on Acoustics 被...
4.14.2.1.3 Reduction of seismic noise Existence of the above mechanism suggests that, if a seismic/gravity instrument is co-located with a barometer, one can reduce the level of noise considerably by taking advantage of this correlation. For analyses of tidal and lower-frequency data, this has...
That helps with noise reduction. It is much quieter than recently built motels. I have only had this problem once in the 20 yrs I have going there. I also like to go in the winter because it is not crowded and is much quieter. They have great monthly rates in January and February....
