(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 disembarkation of aircraft;
 (e) operation of fixed audible alarm or warning systems.
 (2) Noise generated from an activity mentioned in subclause (1) should not exceed the background noise level at the sensitive receptor site:
 (a) between the hours of 07:00 and 22:00—by more than 5 dB(A); and
 (b) between 22:00 hours of a day and 07:00 hours of the next day—by more than 3 dB(A).
 (3) For subregulation (2), the sound pressure level of a particular noise is the sound pressure level that is exceeded for 10% of a period of at least 15 minutes, adjusted to take account of tonal character and impulsiveness (if any) of the noise.

Part 3—Commercial receptors

3.01  Application
  This Part applies to sites of commercial receptors, and a reference in a provision of this Part to a sound pressure is a reference to sound pressure measurable at the site of a commercial receptor.

3.02  Noise from any source
  For sites of commercial receptors, the indicators of noise that is excessive are the indicators mentioned for sites of sensitive receptors, but the following considerations also apply in determining whether noise is excessive at a particular site:
 (a) the nature of the business conducted at the site;
 (b) the time of day when the noise occurs;
 (c) the duration of the noise;
 (d) the nature and characteristics (if any) of the noise;
 (e) the background noise level.

Part 4—Measuring noise

4.01  Procedures and standards
 (1) This clause sets out the procedures and standards to be applied by an airport environment officer in measuring noise for the purposes of the regulations.

Procedure
 (2) In making a measurement, an airport environment officer must do so:
 (a) at the most affected site of sensitive receptor, or commercial receptor, as the case requires; and
 (b) by a procedure that is in accordance with:
 (i) the relevant Australian Standard (if any) as in force at the commencement of these regulations; or
 (ii) if a procedure is detailed in the final master plan (if any) for the airport concerned—that procedure; or
 (iii) if neither paragraph (a) or (b) apply—a relevant procedure published by the International Organisation for Standardisation (if any), as in force at the commencement of these Regulations.
 (2A) Paragraph (2)(b) applies to a measurement of noise generated at, over or under Sydney West Airport before the first final master plan is in force for that airport as if:
 (a) the words "detailed in the final master plan (if any)" were
