Building Acoustic
Sound Insulation Measurements in Buildings
Building acoustics focuses on how sound behaves within rooms and how it passes through walls, floors, and façades. Robust acoustic performance is essential for occupant comfort, a clear indication of construction quality, and demonstrable compliance with national and international standards.

Standardised acoustic measurements
Across residential, commercial, and industrial projects, standardised acoustic measurements provide verifiable evidence of how effectively building elements control noise transmission between neighbouring spaces, from external sound sources into the building, and from structure-borne impacts such as footsteps, and machinery.
What is evaluated in building acoustics?
Building acoustics measurements address how sound:
-
Is transmitted within and between rooms
-
Passes through building elements between adjacent spaces
-
Enters buildings from outdoor sources
The purpose is to deliver reliable, standardised data on the acoustic performance of walls, floors, façades, and other structural elements, providing a clear basis for design validation, compliance, and quality assurance.
Measurement accuracy and standard compliance
Reliable building acoustics testing requires Class 1 instrumentation compliant with IEC 61672.
Frequency analysis in octave and one-third octave bands must comply with IEC 61260, while reverberation time measurements are typically performed according to ISO 3382.
Field and laboratory sound insulation measurements are conducted in accordance with ISO 16283 and ISO 10140.
