Test for Rating of sound insulation in buildings and of building elements –Airborne sound insulation helps simplify the development of sound code requirements; proactively control quality during the production process and optimize research and development of building elements.
Overview of the Test for Rating of sound insulation in buildings and of building elements –Airborne sound insulation
Test name: Test for Rating of sound insulation in buildings and of building elements –Part 1: Airborne sound insulation.
Test method: ISO 717-1:2020: Acoustics – Rating of sound insulation in buildings and of building elements – Part 1: Airborne sound insulation [1].
Conducted at: Laboratory, the Institute of Development & Application for Sound Materials (DASM)
1. Test target and subjects
– Test target
- Determination of single numerical quantities for airborne sound insulation in buildings and building components such as walls, floors, doors and windows.
- Consider the different sound level spectrum of different noise sources, such as noise sources inside the building and traffic outside the building.
- Give rules for determining these quantities from the results of measurements made in the one-third octave or octave range, for example according to ISO 10140-2 and ISO 16283-1.
- A number adapted from this document to evaluate airborne sound insulation and to simplify the development of acoustic requirements in building codes. Evaluation of an additional number in 0.1dB steps is indicated to indicate uncertainty (except for spectral adaptation terms). The required numeric values of a number quantity are specified according to different needs. Numerical quantities based on measurement results in one-third octave range or octave range.
- For laboratory measurements carried out in accordance with ISO 10140-2, single quantities are calculated using one-third octave bands only.
– Test subjects
Evaluate the sound insulation of certain structures in new or renovating constructions using a single weight instead of a conventional air sound insulation curve according to ISO 10140-2 and ISO 16283-1.
2. Experimental procedures
Experimental procedure used for experiments with impedance tubes.
Steps:
- Prepare and arrange equipment and materials for testing.
- Equip the laboratory according to ISO 10140-2.
- Perform testing.
- Processing and reporting results
