What should I include in a scope for an acoustic consultant?

Summary: Assesses noise and designs walls, windows and roofs to meet noise limits.

Why it matters: Attached dwellings must meet NCC sound insulation rules between homes. Sites near main roads, rail or airports may have noise conditions.

When needed: Duplex or attached dwellings, or sites in a noise overlay.

Minimum scope by stage

• Design: noise assessment; construction recommendations (glazing, wall and roof build-ups)
• Planning or building approval: acoustic report; sound insulation details for separating walls and floors (attached dwellings)
• Construction: review of product substitutions affecting acoustic performance
• Completion: compliance letter or testing where council conditions require it

Options

• Noise logging on site
• Mechanical plant (air-con, pool pumps) noise advice
• Post-construction testing

Meetings and site visits: Desktop, or one visit for noise logging; testing visits priced separately.
