The Technical Sound Supplement is optional and primarily intended for councils to assist in the development of the sound management for a SEP. It is mandatory for councils to develop sound criteria for a SEP and include in a precinct management plan.

The Technical Sound Supplement is an optional technical resource that supplements the Guidelines with detailed information on sound management to help local councils develop the sound criteria required as part of a precinct management plan (PMP). It includes:

  • an overview of considerations and approach to developing sound criteria for a SEP
  • the aims and objectives of the SEP/s, along with key principles that inform the development of criteria and requirements.
  • definition of optional quantitative sound criteria for different development types and development controls included in a precinct management plan that relate to sound-emitting uses (emitters) and sensitive-receiver development (receivers) for areas within and around a SEP/s.
  • requirements and procedures adopted for development applications.
  • approach to assessing development compliance and responding to complaints about noise impact.

The Technical Sound Supplement is an optional technical resource. It includes example sound controls for different development types that councils can with specialist advice, adapt to suit the specific conditions of each precinct. Alternatively, councils can commission specialist advice to start from scratch and prepare a set of sound controls for their precinct.

However, it is mandatory for councils to develop sound criteria for a SEP and include in a precinct management plan. Step 1.5 of the SEP guidelines requires councils to:

  • prepare a place-based sound management framework to regulate sound from both licensed and unlicensed premises and ensure that new development is designed to mitigate sound from a single premises or SEP.
  • include the sound management framework for a SEP (or single premises), in the precinct management plan and a council’s development control plan to accord it more statutory weight.
  • consult with and obtain feedback from L&GNSW during the preparation of the sound requirements to ensure that the SEP requirements align with L&GNSW’s assessment framework for managing complaints from licensed premises.
