Hi All.
I got the DA approval from Baulkham Council. Since this Block is backing on to Main road . I was asked to submit a Road noise report which recommendation as below.
From the DA consent letter:
6. Acoustic Requirements
The recommendations of the Acoustic Assessment and Report prepared by Noise and Sound Services, referenced as nss22067 - Final,
dated April 2014 and submitted as part of the Development Application are to be implemented as part of this approval. In particular: The provisions of Table 2 of Section 6 - Recommendations.
From the Noise report.
From the Road and noise report . Referring to Section 6
6. RECOMMENDATIONS
This section provides the minimum construction requirements to meet the internal noise goals.
6.1 External Wall Construction
The external walls must have a minimum Rw of approximately 40 dB, which is
standard for brick veneer consisting of 110 mm thick exterior face brick, with 90 mm deep timber stud or 92mm metal stud and 13 mm thick plasterboard internal
wall constructions and R1.5 thermal insulation in the wall cavity.
6.2 Roof / Ceiling Construction
The roof/ceiling must have a minimum Rw of 38 dB, which is standard for a
concrete tiled roof with sarking and a 10 mm thick plasterboard ceiling fixed to
the ceiling joists and R3.5 thermal insulation in the roof cavity. The plasterboard
walls and ceiling should be well sealed. The joint between the wall and ceiling
can be sealed, for example, with a resilient layer such as mastic and covered with
a plasterboard cornice or the joint can be sealed with tape and cornice cement.
6.3 Minimum Glazing Thickness and Rw Ratings
To meet the internal design goals, as given in Section 3.3 above, the glazing in
the rooms of the dwelling will require the glass thicknesses specified in Table 2
below to give the recommended Rw ratings.

bedroom at 6.38 Laminated glass ..and so for other windows.
Notes:-
? All other glazing to be a minimum of 4 mm thick float glass for habitable
rooms with a minimum Rw or STC rating of 22 dB;
? Rw = Weighted Sound Reduction Index, covers a frequency range from
100 Hz to 3.15 kHz;
? STC = Sound Transmission Class, covers a frequency range from 120 Hz
to 4 kHz;
? Glazing systems recommended are minimum requirements for acoustic
purposes. In some cases thicker glass may be required for safety or other
reasons.
6.4 Ventilation
Specific ventilation requirements are outside of our scope of expertise; however
an acoustically insulated building must be kept virtually air tight to exclude
external noise. Therefore mechanical ventilation or air-conditioning is needed to provide fresh air to control odours. Requirements for ventilation are given in the Report nss22067 ? Final Page 8
Building Code of Australia (BCA) part 3.8.5. Indoor air quality is given in
Australian Standard AS 1668.2 -2002, ?The use of ventilation and airconditioning in buildings - Ventilation design for indoor air contaminant
control?.
Night time noise levels of any outdoor air-conditioning units must meet the
requirements of the Protection of the Environment Operations (Noise Control)
Regulation 2008.
7. SUMMARY AND CONCLUSIONS
Noise and vibration from road traffic movements using Windsor Road, Beaumont Hills has been measured in the vicinity of lot xx, street, Hills, NSW 2155. The measurements have been used to predict internal noise
levels for the proposed dwelling. No exceedences of the internal noise or
vibration levels are predicted. This is providing that the recommendation details shown in Section 6 above as fully complied with. Mechanical ventilation or air conditioning is recommended.
Now the question is . From the DA consent i understand the i need to have a thicker glass as per the Table 2 of section 6 . Which I'm doing it along with 13mm
But the recommendation was to have a ventilation per the Noise though its outside the scope of this report.
From the builder side it been said i need to have ducted before the completion and have to be in there before practical completion. I like to do this later via third party if its a compulsion from council.
Anybody heard of this council forcing to have a ducted aircon
I really don't want to spend money on this Aircon now
