They can also prevent sound sources, such as speakers, from being placed too close to the corners of the room where noise is easily amplified by wall reflections. • Flooring - Floor construction can help reduce noise infiltrating into a residence. Resilient underlayment and dampening compounds can decouple [or

Frequency Domain Analysis of Operation Remember that b(t) = s(t)2cosωct. So B(ω) = S(ω +ωc)+S(ω −ωc) This translates the sidebands around ±ωc down

4 EXPOSURE CRITERIA, OCCUPATIONAL EXPOSURE LEVELS
www.who.intPermanent noise-induced hearing loss is related to the sound pressure level and frequency distribution of the noise, the time pattern and duration of exposure, and individual susceptibility. The ability to hear and understand everyday speech under normal conditions is regarded as the most important function of the hearing mechanism.
