Sound Insulation in Buildings,ilings, walls, doors and windows is important. Second, a sufficient structure-borne sound insulation, also called impact sound insulation, for the ceilings, has to be provided especially. Finally, the service equipment should be sufficiently quiet.

Silencers, cooling towers (Fig. 11.1) or flue gas stacks of power plants to protect the neighbourhood from plant noise. Large silencers are also required for ventilation openings of rooms with high internal sound pressure levels, e.g. industrial production halls or subway ventilation ducts.

Noise and Vibration from Railroad Traffic, population towards noise, especially road traffic noise. This sensitivity has constantly increased since then and has significantly influenced the legislation concerning traffic noise. Today, in Germany all construction plans for traffic routes must also include an ensured prediction of the effect of noise on the residents.

Ghulam Murtaza,William G. CottsSound consists in mechanical vibrations within the frequency band of human hearing from approximately 16 Hz–16 kHz. Vibrations in air and in liquids are called airborne and liquid-borne sound respectively, vibrations in solids are called structure-borne sound.

Furthermore, the transfer from structure-borne sound into airborne sound – the vibration-induced radiation of sound – should be kept as low as possible.
