ENJOY SILENCE
Higher living standards require lower noise production of installed drainage systems. You expect a quiet environment, total piece of mind and a good night sleep.
NOISE IN A SOIL & WASTE SYSTEM
Every object in motion makes noise transmitting its vibrations to the surrounding air as pressure waves. There are two types of noise in soil & waste systems:
AIR-BORNE NOISE
This is sound that travels through the air from its source. The source causes the air to vibrate. Air-borne noise can pass through structures and is reduced by using absorbent materials.
STRUCTURE-BORNE NOISE
This is sound that first occurs through a solid structure generated from a vibrating source or impact event. The vibrations pass through the structure and reach the human ear as air-borne noise at different locations within the building. The building structure acts as an acoustic bridge. Structure-borne noise is reduced by using soft material to acoustically uncouple the vibrating source or impact event.
SOUND REDUCTION WITH DBLUE
Noise in a soil & waste system is caused by waste water flowing inside a drainage pipe system. The waste water is turbulent and causes noise as well as vibrations in the pipe structure. The vibrations are emitted directly from the pipe surface as air-borne noise and as structure-borne noise to the wall through the fixing system. dBlue has been designed to reduce both air-borne and structure-borne noise.
HOW DBLUE REDUCES AIR-BORNE NOISE
Air-borne noise is reduced using absorbent materials. The plastic PP-MD used for dBlue is a special formula adding sound-dampening mineral fillers with increased weight to maximise the absorbance of air-borne sound waves. The triple layer pipe and rubber ring joints further reduce acoustic vibration in the system.
HOW DBLUE REDUCES STRUCTURE-BORNE NOISE
Structure-borne noise is reduced by using soft material to acoustically uncouple the vibrating source or impact event. The dBlue acoustic bracket has a special rubber lining designed to best uncouple any vibrations from the pipe system.
The combination of all these features is what makes dBlue a system that takes reduction of soil & waste noise to the next level. Non-system specific installation practice will also benefit a lower noise level, like to install the pipe systems to the heaviest wall and to properly insulate a pipe section passing through building slabs and other structural barriers.
