Noise limit
up to 138 dB(A) LWA pass-by, 128 dB(A) on busy days
Bilster Berg runs a per-car sound-power limit alongside a daily allowance for the whole circuit, so the ceiling drops when the day is full or the entry is loud. Around 95 dB(A) is the practical recommendation, and loud GT cars are often asked to fit an extra silencer.
