Human habitats and activities have changed dramatically over the ages, and the sound environment in which we live today would have been unimaginable even a hundred year ago. Today’s world is often noisy. More than half the population now lives in cities, which continue to densify. Yet noise pollution is not inevitable: noise can be combated in various ways during building and renovation works.

What impact does noise have on our comfort?

The effects of noise are not just confined to our ears. Excessive noise can affect the whole body, ranging from discomfort to effects including cardiovascular problems, reduced attention span and memory capacity, agitation, reduced field of vision and gastrointestinal problems.

Sleep can be disturbed by noise levels above 35 dB. Prolonged exposure can result in problems getting to sleep, waking up in the night, the shortening of some stages of sleep, and reduced overall sleep quality.

How does noise pollution spread?

How does noise pollution pass through walls?

When a noise meets a wall, its sound energy splits up. Some of it is reflected back towards the source, some is absorbed by the wall and converted into heat, and the rest is transmitted to the air in the adjoining room, causing it to vibrate and transmitting the noise to the occupants.

Noise pollution is caused by two types of noise:

  • Noises passing through the air cause the room’s walls to vibrate. The wall vibrates and, in turn, causes the air in adjoining rooms to vibrate: These noises include sound from inside the building (conversations, hi-fis, televisions) and from outside(road traffic, trains, planes).
  • Noises travelling through ceilings, walls, pipes and floors vibrate and spread sound waves through the air in the adjoining room. The sounds can include impact noise (footsteps, scraping, furniture moving, things being dropped, showers), noise from shared-use equipment (lift, boiler room) and noise from individual equipment (toilets flushing, bathroom fittings, showers).

What is sound insulation?

Sound insulation reduces sound energy, either by absorbing it or reflecting it back to source. This reduction is measured by the sound intensity level, which tells us the acoustic properties of a material such as a construction component.

Silentcare for acoustics

Weber has developed innovative solutions designed to improve acoustics in buildings, by reducing impact or/and airborne absorption noise in both floors and walls. Our solutions consist of multi-components including premix mortars, acoustical mat, and other accessories.
