PPT-Lec.5 Noise Pollution 4

th year The Environmental Effects of Noise 51 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 Fig51 This oscillation is finally transmitted to the fluidfilled 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 T. 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 In this PPT we will learn:-.

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 .
