Following similar contributions on the measurement of airborne sound insulation (part 1) and absorption coefficient in reverberation rooms (part 2) this part 3 introduces a data collection on interlaboratory tests on the measurement of impact noise level and impact noise reduction. The data base comprises 1614 one-third octave band spectra in total. The data is analysed in one-third octave bands and also for single-number quantities. Typical average values are derived for the standard deviation of reproducibility, the in-situ standard deviation and the standard deviation of repeatability. The typical values are compared to the values currently standardised in ISO 12999-1 for airborne sound insulation, impact noise level and impact noise reduction to check whether their values are reasonable within the system of existing typical values. Finally, proposals for a possible revision of ISO 12999-1 are derived.
