PPT-Lec.2 Noise Pollution 4

th year 21 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 handheld 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. 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 lnput at 1kHz 1mV RMS PreEmphasized FREQUENCY Hz 20 02000 DEVIATION dB 00 020000 040000 060000 100 1k 10k 50k 04000 06000 08000 1000 080000 10000 18V 25 25 MEASURED COMPUTER SIMULATED T1115 TA02 INPUT SELECT PER PHOTO CART RIDGE COM IN 475k MM 100 Emily Dickinson Lecture. 15. th.

The style of GPS data collection and processing suggests that one or more GPS stations is moving (e.g., car, aircraft). In developing countries, water pollution is caused mainly from dumping raw sewage into the water supply.. In developed countries, water pollution comes mainly from 3 sources. Municipal pollution. Industrial pollution.

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.
