A Comparison of Beamforming Processing Techniques for Low

Due to the massive nature of mining equipment, these machines are built using large and thick steel panels and thus radiate noise mostly at low frequencies, i.e., 200 Hz to 1000 Hz. The challenge of using phased arrays for mining applications is then related to the frequency range of interest and the resolution obtained at such frequencies.

5. Noise Management WHO

The goal of noise management is to maintain low noise exposures, such that human health and well-being are protected. The specific objectives of noise management are to develop criteria for the maximum safe noise exposure levels, and to promote noise assessment and control as part of environmental health programmes. This is not always achieved (Jansen 1998). The United Nations´

Occupational noise exposure and hearing a systematic

07/08/2015 · Carbon disulfide was shown to reduce hearing in the low frequencies in a study of 346 rayon wool workers, where 105 were exposed to equivalent noise levels of 8090 dB, 132 were exposed to a combination of noise and carbon disulfide, and the rest were not exposed (Chang et al. 2003). The hearing loss was about 10 dB in both exposed groups compared to the nonexposed.
