level for a 24 hour period of measurement; and
 (c) 55 dB(A), calculated as the equivalent continuous A‑weighted sound pressure level for an 8 hour period of measurement from 22:00 hours on a particular day to 06:00 hours on the following day.

2.05  Noise from ground‑based aircraft operations
 (1) For ground‑based aircraft operations, there are no indicators of noise that is excessive, but the following considerations apply in determining whether noise is excessive.
 (2) Noise from ground‑based aircraft running for any reason should only be generated in a manner that is consistent with:
 (a) within 1 year after the airport at which the ground running is being conducted is first leased—guidelines for ground running published by the Federal Airports Corporation and in effect when these Regulations are made; or
 (b) at a time after 1 year after the airport is first leased—express provision in the final master plan for the airport.
 (3) In relation to other ground‑based operations and in relation to ground‑based aircraft running at times other than a time to which subclause (2) applies, matters to be considered are:
 (a) the distance between the source of the noise and the site of the sensitive receptor; and
 (b) the background noise level;
 (c) the time of day when the noise occurs; and
 (d) if the noise source is an aircraft engine—the power setting of the engine;
 (e) anything included in the final master plan (if any) for the airport at which ground running is being conducted that is relevant to this clause.
 (3A) This clause applies to noise generated from ground‑based aircraft running at Sydney West Airport before the first final master plan is in force for that airport as if:
 (a) the words "express provision in the final master plan" were omitted from paragraph (2)(b); and
 (b) the words "the conditions in an airport plan" were substituted in paragraph (2)(b); and
 (c) the words "final master plan (if any)" were omitted from paragraph (3)(e); and
 (d) the words "conditions in an airport plan" were substituted in paragraph (3)(e).
 (4) In this clause:
ground‑based aircraft operations means:
 (a) operation of an auxiliary power unit of an aircraft; or
 (b) ground‑based aircraft running; or
 (c) test‑bed running of an aircraft engine removed from an aircraft.
ground‑based aircraft running means test operation of an engine attached to an aircraft.

2.06  Noise from other airport operations
 (1) This clause applies to noise generated from any of the following activities:
 (a) aircraft refuelling;
 (b) activities in connection with aircraft that do not involve the operating of an aircraft engine (for example, moving, maintaining or repairing aircraft);
 (c) operation of plant or machinery;
 (d) assembling of passengers or goods in connection with embarkation or
