PPT-NOISE POLLUTION Noise is defined as an unwanted or undesirable sound.

The threat of noise pollution is increasing with the rapid pace of urbanization and industrialization Unwanted sounds not only cause discomfort and irritability to animals but can also lead to . EPA can also help identify the right authority to contact for other noise complaints Visit epavicgovau for more information on noise pollution Environment Protection Authority Victoria EPA Victoria is the states independent environmental regulator U This does not include me.

The attenuation produced, in dB per meter run of duct, depends ‎on α, the sound absorption coefficient of the lining material and the ratio of perimeter to cross ‎sectional area of the duct (P/S).‎. th. year. 2.1 . Types of Noise . 1- Continuous Noise. Continuous noise is produced by machinery that operates without interruption in the same mode, for example, blowers, pumps and processing equipment. Measuring for just a few minutes with hand-held equipment is sufficient to determine the noise level. If tones or low frequencies are heard, the frequency spectrum can be measured for documentation and further analysis. OLUWADARE,T.. DEPARTMENTS OF COMMUNITY MEDICINE & PUBLIC HEALTH. Introduction .

The Environmental Effects of Noise. 5.1 The Ear . . When a sound wave enters the ear, it sets the eardrum into oscillation, which in turn causes oscillation of the three tiny bones in the middle ear called the ossicles, Fig.5.1. This oscillation is finally transmitted to the fluid-filled inner ear, the motion of the fluid disturbs hair cells within the inner ear, which transmit nerve impulses to the brain with the information that a sound is present.
