Underwater Hearing Thresholds [PDF]
The Journal of the Acoustical Society of America, 1956 Underwater hearing thresholds were measured at frequencies of 250, 500, 1000, 2000, and 4000 cps on four Aqualung equipped divers with normal hearing in air. In the frequency range investigated, the minimum audible fields underwater are from 44 to 60 db greater than the minimum audible fields in air, and the shape of the threshold vs frequency curve is
