Noise in buildings is considered to be detrimental to health and the quality of life. Where efforts are made to attenuate the sounds coming from the street, the perception of the sounds emitted within the buildings are worsened. Heat insulation policies aiming at reducing energy consumption will also heighten these perceptions. When comparing performance of drainage materials, acoustic performance is reckoned to be second only to fire safety. Cast iron pipe systems have intrinsic acoustic properties. Owing to the development in accessories equipment, they offer outstanding performances.
What is the meaning of “equipment noise” exactly?
Noise emitted by waste water pipe systems is classified under the regulation in the «equipment noises». Noise originating from pipe systems is due to the sound energy produced by water/air turbulence, but mostly by the mechanical effect of the water-flow on the internal pipe walls.
