The Test for Evaluation of sound insulation in construction works and construction structures –provides useful information to help control quality during the production, design, construction, finishing … of all types of floors to ensure optimal soundproofing performance.
Overview of Evaluation of sound insulation in construction works and construction structures
Test name: Evaluation of sound insulation in construction works and construction structures – Part 2: Impact sound insulation.
Test method: ISO 717-2:2020: Acoustics – Rating of sound insulation in buildings and of building elements – Part 2: Impact sound insulation [1]
Conducted at: Laboratory, Institute of Development & Application for Sound Materials (DASM).
1. Test target and subjects
– Target
Determinate single numerical quantities for impact sound insulation in buildings and floors.
Give rules for determining these quantities from the results of measurements made in the one-third octave range according to ISO 10140-3 and ISO 16283-2, and in the octave range according to that option in ISO 16283-2 for field measurement indicators.
Determinate single numerical quantities for impact sound reduction of floor coverings and floating floors calculated from the results of measurements carried out in accordance with ISO 10140-3.
Specify a procedure for evaluating the reduction in negative pressure due to the impact of floor coverings on light floors.
A number appropriate to this document is intended to evaluate impact sound insulation and to simplify the development of acoustic requirements in building codes. Evaluation of an additional number in steps of 0.1dB is indicated where necessary for the expression of uncertainty (except for spectral adaptation terms). The numeric values of a numeric quantity are specified as necessary for the calculation.
Evaluation of the measurements over the extended frequency range is given in Annex A.
The method for obtaining single quantities for bare heavy floors according to their performance when combined with floor coverings is given in Appendix B.
Examples of calculations of numerical quantities are given in Appendix C.
Evaluation of measurements with heavy/soft impact sources (rubber ball) is given in Appendix D.

2. Experimental procedure
Steps:
- Prepare and arrange equipment and materials for testing.
- Equip the laboratory according to ISO 10140-3.
- Perform testing.
- Process and report the test results
The role and importance of Test for Evaluation of sound insulation in construction works and construction structures
The test for determination of sound insulation in construction works and construction structures conducted by the Institute of Development and Application for Sound Materials helps meet all practical needs of customers, manufacturing enterprises, research development (R&D), use of desired floor types:
- Meet soundproofing standards for projects and construction items.
- Control quality during production.
- Optimize research and development of soundproofing capabilities for various floor materials and structures.
- Get an factual basis to propose and implementing solutions that prioritize appropriate materials, products … that possess effective soundproofing capabilities for floor.
- Provide certificates and test results to increase competitiveness – sales, or put products into installation, use, construction… in works and projects transparently, compliantly and efficiently
- Simplify the development of acoustic requirements in building codes
In addition, if the test sample does not meet the standards, DASM will consult and design solutions for shape/structure/materials used to calibrate the design in a streamlined, effective, and cost-saving manner.
