Noise leakage despite having fold able acoustic doors dividing gym into 2 usable areas.
Above the dividing wall there was a single breeze bloc wall that was a weak spot. Install MF acoustic 12cm wall comprising independent aluminium framework, 1 layer of fermacel,1 layer sound shield,all joints overlapped, perimeter sealed.
Leakage eliminated. Soundproofing complete solution which it should have had in first place.
