Abstract
Initially the onus was put on DJ’s to limit or control noise emission from entertainment venues, often by crude indicator lights when a certain level was exceeded. It is not surprising that such efforts were quite unsuccessful. With the party mood getting hotter, the volume would creep up with the DJ’s usually yelling above the music level. With the type of rock and pop music involving increasingly heavy bass beat and with ever more powerful bass bins the situation got rapidly worse. The initial reluctance or inability by some operators to positively control the music levels resulted in many venues being closed down by the Local Authorities.
