Generator Noise
Greenwich requires a muffler or equivalent noise-reduction apparatus on any stationary internal combustion engine or air-compressor equipment, a rule that reaches portable and standby generators. Skipping the muffler, or venting exhaust and steam blow-down straight into the open air, is a separate noise-chapter violation regardless of the decibel reading.
