Reputable and decently priced acoustic consultants in Melbourne

Similar to the question for Sydney,  we are trying to find the same but in Melbourne.

The firms I’ve contacted so far are not very interested in smaller properties. Ours is 12 apartments.

We’ve had a number of complaints from residents about various aspects of building noise including.:

Noisy stairwells
Noisy stairs
Noisy doors
Noisy car park extractor fans
Noisy apartment ventilation fans

Some of these are subjective. The EC wants to get objective noise measurements and solution recommendations.

Thanks for any help!
