Sound Insulation Testing – Sutherland Street, London

THE BRIEF

We were instructed to complete Sound Insulation Tests on this change of use building
These tests consisted of a mixture of Airborne Floor and Impact Floor tests

To pass an Airborne test, you must score 43db or higher (45 on new build properties)
Airborne tests measure the difference in sound levels between the receiver room and neighbouring walls or floors
If the sound output in the receiver room is 100db and the sound leakage being passed through into the neighbouring room is 40db, then the result would be 60 and therefore would be a pass
To pass an Impact test, you must score 64db or lower (62 on new build properties)
Impact tests measure how effectively the Sound Insulation between floors cancels out sound. If there is less than 64 decibels of sound leaking through into below floors then the test would be a pass

THE PROCESS

After reviewing drawings, on site testing was ready to be completed. All calibrated equipment was setup in accordance to our strict procedures to ensure the most accurate result possible
