Low Frequency Sound Transmission into Offshore Cabin

The strongest helicopter noise is found at frequencies below 100 Hz. Helicopter landing and take off at platforms can cause sleep disturbances. Offshore space is premium. Cabins therefore tend to be compact. Cabins are also module-built and installed side-by-side, which leads to complicated acoustic interrelation regarding flanking transmission paths. To further compound the issue, a platform is very stiff compared to an ordinary building on land. Many of the truths known in building acoustics, therefore, do not hold. At low frequency, stiffness is the governing factor for sound transmission...
