Noise pollution - measurements and means of building protection
Very often the problem of building users is unwanted sound exposure - the noise from the highway near the office or the noise from constant construction work near the house. It directly affects the productivity of our work or the quality of our recreation.
Why measure noise levels during construction and operation?
Very often the problem of building users is unwanted sound exposure - the noise from the highway near the office or the noise from constant construction work near the house. It directly affects the productivity of our work or the quality of our recreation. The intensity of sound decreases as it spreads over a large area. Therefore, the first thing to do to reduce the impact of noise is to locate the building as far away from the source as possible.
If this is not possible, rooms can be protected from noise in other ways:
☑️ Locate areas closer to the source where noise will not cause discomfort, such as technical and utility rooms; ☑️ Use building materials that protect against noise; ☑️ Locate door and window openings away from sources; ☑️ Plant trees and shrubs to diffuse sound; ☑️ Locate earthen masses between the building and the source (e.g. earth banks); ☑️ Plant a lawn - it is more absorbent than a solid reflective surface
Noise pollution assessment is required by BREEAM, LEED, and WELL standards.
A prerequisite for scoring is the involvement of a qualified acoustician in the pre-stage P phase to assess the noise parameters in the building and on the premises.
The following are the main factors influencing acoustic comfort in a building:
☑️ Correctly sized glazing (with the appropriate insulation index). ☑️ Location of engineering equipment - to reduce the noise impact, it is recommended that the main systems (refrigeration centers, ventilation chambers) be located outside the building boundaries if possible. ☑️ Proximity to highways, railways and airports. The main source of external noise is road transport. ☑️ Office partitions must have an insulation index corresponding to the calculated noise levels. Measurements are taken using a noise-vibrometer that is regularly calibrated.
