Acoustic solutions for commercial air conditioning units

Supplier: Modular Wall Systems

Enterprise Data Baulkham Hills, NSW, a national data storage company, utilises large air conditioning (AC) units which run 24 hours a day in order to maintain their temperature controlled rooms at a constant level.


With imminent expansion of their business, Enterprise Data required approval from the local council to install additional AC units at their premises.

The council identified that these AC units were causing disturbance to the nearby residents especially during night time operating hours, and accordingly enforced an order that the company must mitigate noise levels from these units or risk being shut down.


Modular Wall Systems reviewed the acoustic assessment and noted that due to close proximity of hard surfaces, refl   barriers were not suitable for the challenging requirements of this project. Hence, our leading-edge sound absorbing wall, AcoustiSorb™, was identified as the best fit.

This design comfortably exceeded the council requirements. The full system was then constructed and painted onsite in less than 2 days. In total, the wall was built 42m long and 3.9m high and achieved an NRC (Noise Reduction Coefficient) of 0.95 and an RW (Weighted Sound Reduction Index) of 28.
