Acoustic Tapping Test

Acoustica’s product range of noise control solutions for flooring systems has been repeatedly independently tested to consistently achieve five and six stars in the Association of Australian Acoustic Consultants (AAAC) star rating system. However, results will vary depending on the construction, substrate and surface materials of each project.

Acoustica can refer you to a reputable acoustic consultant to conduct site specific testing* who will provide certification for each project site, prepared in accordance with the International Standard ISO 16283-1:2014 Acoustics — Field measurement of sound insulation in buildings and of building elements — Part 1: Airborne sound insulation (refer ISO 140-7:1998).

There is a charge for this service*.


The BCA provides minimum construction standards for various building classes including acoustic privacy.

The BCA requirement is a weighted standardised impact sound pressure level with spectrum adaptation term Ci, of less than or equal to 62 Lnt,w+Ci.

However, the reality is that this is in most cases unacceptable to occupants and can result in the need for costly reparation works.

In response the Association of Australian Acoustic Consultants (AAAC) has developed the star rating system to rank the acoustical quality of apartments and provide guidance in the design and construction process.


The AngelStep® GOLD8 product is an acoustic underlay for the treatment of Impact and airborne noise transfer. Its construction combines a highly effective support and cushion. It provides maximum performance for minimum thickness combining an impact and vibration dampener and sound absorber.

The performance of AngelStep® GOLD8 is due to its unique and patented construction – a laminate of double needle punched high density sound absorbent polyester and a resilient ‘cross linked’ microcellular foam. It is nominally 8mm thin & is supplied in tiles 1150x1150mm.
