... ground vibration and transmission of air borne noise A steel water tank (2x1 5x1 5 m) was positioned on antivlbration mounts, which attenuated the ground vibration noise transmission by at least 40 dB at all frequencies above 0 01 kHz The ambient noise SPL in the laboratory was reduced to less than 10 dB...

... into the hood. The breathing noise frequency spectra of these time histories (obtained via the FFT technique) indicates that the sound is predominantly low frequency, in the region below 1 KHz (Figure 2). The extent to which the human ear is able to respond to waterborne sound at these low frequencies...
