6.6.2 Construction Category Requirements
AS 3671 classifies a Noise Reduction of > 10 dB up to 25 dB as a Category 2 construction:

‘Category 2. Standard construction except for lightweight elements such as fibrous cement
or metal cladding or all-glass facades. Windows, doors and other openings must be closed.
TNR of approximately 25 dB(A) is expected.’

AS 3671 classifies a Noise Reduction of > 25 dB up to 35 dB as a Category 3 construction:

‘Category 3. Special construction, chosen in accordance with Clause 3.4. Windows, doors
and other openings must be closed. TNR of approximately 25 and 35 dB(A) is expected.’

Based on the required noise reductions presented in Tables 5.5 and 5.6, all proposed buildings
require either Construction Category 2 or 3 specifications. Air conditioning units should be provided
for all rooms requiring category 2 or 3 construction to allow adequate ventilation for occupants while
maintaining acoustic performance.
