include :
|
|
1. |
verification of
compliance with requirements of Building Code of Australia (BCA) - assessment of
transmission of noise between adjacent dwellings (impact noise,
e.g. noise caused by people walking over a timber floor - see also item 8
below, and airborne noise, e.g. noise from amplified music,
noise from conversations - see also items 9 and 10 below);
|
|
2. |
verification of
compliance with recommendations of Australian/New Zealand Standard: Acoustics - Recommended
design sound levels and reverberation times for building interiors (AS/NZS

|
|
5. |
measurements and assessments of road traffic noise on proposed
construction sites (homes, schools, churches, hospitals) for the purpose of
Development Consent
from local councils - assessments according to Environmental Criteria for Road
Traffic Noise laid down by
Environment Protection Authority of New South Wales (EPA), now incorporated
in New South Wales Department of Environment, Climate Change and Water(DECCW);
|
|
6. |

Measurements of sound insulation in buildings and of building elements -
Part 4: Field measurements of airborne sound insulation between rooms (ISO
140-4: 1998);
|
|
10. |
in situ determination of airborne sound insulation
between rooms and of building elements: |
|
|
- |
measurements according to ISO
15186-1:2000 - Acoustics: Measurements of sound
insulation in buildings and of building elements using sound intensity;
and |
|
-
|
based on these measurements, calculations
of the Weighted Sound Reduction Index (Rw) (replacement
of Sound
Transmission Class - STC) according to Australian/New Zealand Standard: Acoustics - Rating
of sound insulation in buildings and of building elements -

ISO717-1:1996);
|
|
11. |
scanning of walls, windows, doors, ceilings and floors
to discover
areas of noise penetration - control
of noise transmitted between adjacent
rooms, control
of intrusion of external noise and control of noise escaping
from clubs, discotheques and pubs;
|
12.
|
evaluation of apartments and townhouses according to
Acoustical Star Ratings of Association of Australian Acoustical
Consultants (AAAC). |
NOTE that
our services listed
under 10 and 11 are based on
state-of-the-art measurements of
sound
intensity. |
