The new acoustic regulations for housing

New Acoustic Regulations (NRA) as of January 2000. It tends to reduce both external airborne noise (other housing, common areas, utilities, transport, etc.) and internal noises (impact, personal equipment, etc.).

In the figure, we see the minimum attenuations (in decibels) required during the construction of new housing.

Individual housing should at least bring about an attenuation of 30 decibels on its external environment. Structure-borne noise (impact noise) transmitted through the floors will muffle the noise level to a minimum of 58 decibels between two neighboring housings.
