ISO 140-11:2005 pdf download.Acoustics - Measurement of sound insulation in buildings and of building elements — Part 11: Laboratory measurements of the reduction of transmitted impact sound by floor coverings on light weight reference floors.
4 Equipment
The equipment shall comply with the requirements of Clause 6.
The tapping machine shall meet The requirements given in Annex A.
The accuracy of the sound level measurement equipment shall comply with the requirements of accuracy Class 1 defined in IEC 61672-1:2002. The complete measuring system including the microphone shall be adjusted before each measurement using a sound calibrator that complies with the requirements of accuracy Class 1 defined in IEC 60942:2003. For sound level meters calibrated for measurements in sound fields of progressive plane waves. corrections for the diffuse sound field shall be applied.
The filters shall comply with the requirements given In IEC 61260.
The reverberation time measurement equipment shall comply with the requirements given in ISO 354.
NOTE 1 For pattern evaluation (type testi’ig) and regular vorefication tests, recorrwnended procodises for sound level meters are given Ii OIML R58l and OIML R88 1
NOTE 2 A method using a modIfied tapping machine and that using a standard heavy/soft Impact source are also introduced In Annex C (wiformatlve) and Annex E (Informative), respectively, for the assessment of Impact sovnd Insulation of a floor ooverlng against real Impact souroes such as human walking and slepplng
5 Test arrangement
5.1 General arrangement
Two vertically adjacent rooms shall be used, the upper one being designated the source room’ and the lower one the recelving room. They shall be separated by a lightweight reference floor on wtiich the floor covering under test is installed.
The airborne sound front the tapping machine that is transmitted to the receiving room shall be such that the level will be at least 10 dB below the level or transmitted Impact sound in each frequency band.
5.2 DetaIls of test arrangement
5.2.1 Source room
There are no specific requirements for the size and shape of the source room.
5.2.2 ReceIving room
The receiving room shall comply with the requirements of ISO 140-1.
The equipment shall comply with the requirements of Clause 6.
