Environmental Impact Assessment of Pump Noise

Noise and vibration present increasing environmental problems to society. Noise and vibration are hazards to human when they occur at high levels, or continue for a long time. High noise levels can cause hearing loss, headaches, dizziness, high blood pressure, loss of concentration, heart disease...etc. There are many researches addressed effect of pumping stations' noise and vibration on perfo...

Environmental noise assessment: Psychophysical background

In this paper, some aspects of the psychophysical background of environmental noise assessment are touched. Psychophysical methods useful for the measurement of environmental noise are mentioned. The simulation of the loudness perception for normal hearing and hearing impaired persons is illustrated. Moreover, the influence of the meaning of sound as well as of additional modalities on noise as...

Noise Impact Assessment

Chapter Summary The two most common types of noise are point source and line source. Natural factors such as topography, vegetation, and temperature can reduce noise over distance. A hard site exists where sound travels away from the source over a generally flat, hard surface such as water, concrete, or hard-packed soil. When ground cover or normal unpacked earth is present between the source a...
