PASM statement on Approved Document E

The new Approved Document E 2003 introduces a new unit of measurement for airborne sound which places much more emphasis on low frequency performance. Due to the inherent difficulties of measuring low frequency noise a significant tolerance on the accuracy of airborne sound test results should be expected. In practical tests PASM have witnessed relatively large variations in airborne sound results by different measurement contractors on the same floor. Site conditions and workmanship can also limit reproducible results; therefore previous results should be viewed as indicative of performance only.
