Noise is one of the by-products produced by construction and engineering works. Whether it is a vertical construction project or a horizontal construction project like road opening, construction work creates noises that can compromise the health of the workers and managers, and also affect the surrounding environments. To ensure that the noises produced are within the bounds of an acceptable level and have complied with regulatory requirements, an acoustic engineering report is prepared for submission to the Council for assessment and to support development. Most acoustic engineering reports cover noise assessment, noise compliance certification and acoustical design for noise control.
Key Factors for Acoustic Engineers
One of the key information included in the acoustic engineering report is the description of the level of road traffic noise in and around the construction site.
Most acoustic engineers will come up with noise traffic modelling, and will also approximate the traffic volume, source of traffic and traffic flow. From the projected traffic volume and flow of vehicles, the report will project the amount of noise that can be expected at certain hours of the day, usually for a 9-hour period, like 10 pm to 7 am. And based on the projected noise levels, the acoustic engineer will propose steps on how to reduce the noise level and ensure the compliance of the project with Council and EPA guidelines.
What an Acoustic Engineering Report Covers
The report will also cover the environmental noise impact and analysis as to how the construction noises and activities will affect the nearby buildings and business establishments. For example, the use of air conditioning and mechanical plants and the operation of heavy equipment units may produce noises that may affect nearby properties and business establishments. This specific component of the acoustic report is ideal for clubs and pubs, hotels, commercial and residential developments.
The advice and recommendations that may be included in the acoustic engineering report may vary depending on the type of construction project. For example, a multi-level apartment construction in Australia will require a different set of expert advice. Acoustic engineers may recommend facade sound insulation to address the external noise intrusion, like industrial noise or road traffic noises. They can also provide noise control recommendations that focus on mechanical plant systems like air-conditioning both to the units within the property and to nearby buildings and establishments.
With Approve it HQ getting your building project done has never been easier, you can get hundreds of different reports without having to research through multiple companies and chase quotes.
Acoustic engineers can provide input and assistance to real estate developer to boost the acoustic quality of the buildings while minimising costs. Acoustic-related solutions are known for their practical application and are easy to construct and implement.
