Summary
Torrance caps noise at 60 dB(A) day and 55 dB(A) night at an industrial site's own property boundary, and 50/45 dB(A) where it reaches homes. Municipal Code Sec. 46.7.2 sets the limits; a data center's steady equipment hum triggers a 5 dB penalty.
It shall be unlawful for any person to operate any machinery, equipment, pump, fan, air conditioning apparatus or similar mechanical device in any manner so as to create any noise which would cause the noise level at the property line of any residential land to exceed the ambient noise level by more than five (5) decibels.

Full Breakdown
Torrance's Noise Regulation, Municipal Code Chapter 6, sets numeric limits by region. Under Sec. 46.7.2.b, industrial-use land outside the refinery regions may not exceed 60 dB(A) during the day (7 a.m.-10 p.m.) or 55 dB(A) at night (10 p.m.-7 a.m.) at its own property boundary. Noise received on residential land is capped at 50 dB(A) day and 45 dB(A) night under Sec. 46.7.2.a. Sec. 46.2.6 separately bars any fan, pump, or air-conditioning apparatus from raising noise at a residential property line more than 5 dB(A) above ambient. A steady audible tone, such as a hum, subtracts 5 dB(A) from the limit.
Violations & Fines
Noise over the Sec. 46.7.2 limits, or fan and air-conditioning noise exceeding ambient by 5 dB(A) at a home under Sec. 46.2.6, is unlawful and enforced by the City through citations and abatement.
