What is BS 5821-3 - Airborne sound insulation of façade elements and façades about?
BS 5821-3 is the third part of the multiple series that:
- Defines single-number quantities for the airborne sound insulation of façades, façade elements, windows, doors, roofs
- Gives rules for determining these quantities from the results of measurements carried out in one-third octave bands according to iso 140/3 and iso 140/5
Who is BS 5821-3 - Airborne sound insulation of façade elements and façades for?
BS 5821-3 on airborne sound insulation of façade elements and façades is useful for:
- Civil engineers
- Researchers of survey
- Construction industries
- Maintenance department of building
- Architects
- Manufacturers of building elements
- Testing laboratories of building elements
Why should you use BS 5821-3 - Airborne sound insulation of façade elements and façades?
Single-number quantity for airborne sound insulation rating is the value, in decibels, of the reference curve at 500 Hz after shifting it according to the method laid down.
BS 5821-3 specifies airborne sound insulation and for simplifying the formulation of acoustical requirements in building codes. BS 5821-3 also specifies the numerical values of the single-number quantities that are specified according to varying needs.
Overall, BS 5821-3 will help you to standardize a method whereby the frequency-dependent values of airborne sound insulation can be converted into a single number characterizing the acoustical performance.
