Experimental Studies on Reducing Noise Pollution and Chemical Pollution of Motor Vehicles

摘要

We all live in an ocean of noise, but until recently this source of pollution has been virtually ignored, its effects not having been considered very palpable. Latest studies have showed that cars, trucks, aircrafts, dance clubs have turned the urban area into an environment with extremely harmful effects on our health. Reduction of noise and chemical pollution from road traffic is a main concern of manufacturers of internal combustion engines. One of the methods used is the use of new materials, among which an important role is taken by the ceramic materials.
