Effects of underwater noise on human hearing.
Polish journal of occupational medicine and environmental health, 1992Hearing conservation for divers and swimmers has been overlooked nearly everywhere in the world. Because submerging a listener changes his or her auditory physiology dramatically, the research upon which we base exposure limits for airborne noise is not pertinent under water.

1974
Abstract : The ability of divers to discriminate the angular separation of two sound sources in the presence of high ambient noise in a reverberant environment was tested. In a first experiment it was found that divers could not discriminate directionality with separations as large as 90 degrees for low signal-to-noise ratios.

The cormorant ear – an adaptation to underwater hearing?
2016Depending on species, diving birds may spend 2-20 minutes under water during a single foraging dive when they may reach depths ranging from one to several hundred meters. Surprisingly little is known about avian underwater hearing despite the fact that several hundred species dive for food.

In-air and underwater hearing of the cormorant
2015Numerous studies have mapped the hearing abilities of birds in air but currently there is little or no data on how diving birds hear or react to sound under water. Therefore, it is unknown whether the ears and auditory system of diving birds are adapted to underwater hearing.

Neoprene wet-suit hood affects low-frequency underwater hearing thresholds.
Aviation, space, and environmental medicine, 2004Psychophysical measures of wet-suit hood sound attenuation are needed to provide the diving community with guidance on protection from underwater sound.Underwater hearing thresholds were obtained from 15 male and 5 female recreational divers with and without a 3-mm thick wet-suit hood.

Underwater Hearing in Seals: The Role of the Outer Ear
1992How sound spreads from water to the inner ear in seals is a problem of particular interest, because seals are semiaquatic mammals and their ears have been adapted secondarily for functioning also in water.
