The brief
-
We were instructed by a Property Management company to conduct Sound Insulation Testing at a set of flats above The Green Man Pub in Harlesden, London
-
The Sound Insulation Tests consisted of Airborne Floor, Airborne Wall and Impact Floor Tests
-
To pass these Airborne test, you must score 43db or hig her
-
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 these Impact tests, you must score 64 db or lower
-
Impact tests measure how effectively the Sound Insulation between floors cancels out sound. If there is less than 62 decibels of sound leaking through into below floors then these tests 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
