Sound and Vibration
1. Building Acoustics
Building Acoustics is the assessment of sound insulation in buildings and building elements. It is important for the well-being of people in their homes, workplace or public venues, and minimum standards are set in the building regulations of each country.
The assessment is based on measured 1/3 octave or 1/1 octave spectra within the 50 – 5000 Hz range. Measurements are carried out in real time (all bands simultaneously).
2. Sound Sources
For the proper measurement of building acoustics a range of sound sources is required that should fulfil the relevant standards, for example ISO140. Brüel & Kjær’s range of sound sources are optimised for building acoustics and include omnidirectional sources for excitation of rooms and partitions, and tapping machines for floor excitation.
3. Vibration Meters
A range of basic and advanced vibration meters and accessories to cover all demands from level checks to in-depth analysis.
