If a sound test fails, what should I do?

If the sound test fails to achieve the minimum rating, there may be an obvious cause such as vents too close together or holes in the party walls/floors. A failure will be the result of insufficient density in the wall/floor, or inconsistency in the building fabric. However noise transfer can be very complicated and a design solution will usually be required by an acoustic engineer. The engineer will design a solution based on the results from the sound test.
