Impact sound transmission of separating floor measurement
Impact sound transmission of separating floors must be measured according to BS EN ISO 140-7 using one-third octave frequency bands, with performance rated as weighted standardised impact sound pressure level (L'nT,w) per BS EN ISO 717-2.
The impact sound transmission of a separating floor should be measured in accordance with BS EN ISO 140-7. All measurements and calculations should be carried out using one-third octave frequency bands. Performance should be rated in terms of the weighted standardised impact sound pressure level (L'nT,w) in accordance with BS EN ISO 717-2.
