Underwater noise from airplanes: An overlooked source of ocean noise
Marine Pollution Bulletin, 2018The effects of underwater noise pollution on marine life are of increasing concern. Research and management have focussed on the strongest underwater sound sources. Aerial sound sources have understandably been ignored as sound transmits poorly across the air-water interface.

Underwater noise generated by vehicle traffic in an underwater tunnel
The Journal of the Acoustical Society of America, 2019Underwater noise measurements were made adjacent to the Monitor-Merrimac Memorial Bridge-Tunnel in the James River, VA during a field experiment in April of 2019. Anticipated sources of underwater noise included wind, waves and associated bubbles, flow noise, boat/ship traffic, industrial shipyard noise and traffic noise radiating from the underwater ...

Effects of Underwater Noise on Larval settlement
2012Many benthic marine organisms possess a pelagic larval phase that typically results in dispersal away from the parental habitat and ends in the larva selecting a suitable benthic habitat in which to settle (O’Connor and Gregg 1998). Settlement and metamorphosis often involve a specific cue or combination of chemical and/or physical cues (Gebauer et al.

Environmental Protection: Underwater Noise and Noise in Port
2022Typically, pollution is considered as the diffusion of toxic or harmful materials on our earth. But pollution can also refer to the propagation of dangerous or harmful sounds in the environment, both in the water and the air. Currently no mandatory regulations are present to regulate noise emitted by ships, only Classification Societies in the recent ...

The issue of the environmental impact of shipping activities is treated in this work from the specific viewpoint of underwater noise emissions from the vessels. There has been recently a rising concern about the negative effects that this kind of emissions can have on the marine wildlife in general and in particular on marine mammals. In these animals,

The anatomy of underwater rain noise
The Journal of the Acoustical Society of America, 1992When rain falls onto a large body of water it produces dominating underwater sound over a broad range of audio frequencies. Laboratory studies using more than 1000 single drops, covering the complete size range of actual rain drops at their terminal speeds, have now shown that the complete underwater spectrum of rainfall sound can be dissected into the

Underwater noise produced by rainfall
The Journal of the Acoustical Society of America, 1987When a liquid drop falling through the air strikes a flat horizontal surface, there are acoustic emissions associated with this impact in both the air and the liquid [G. J. Franz, J. Acoust. Soc. Am. 31, 1080 (1959)]. Under certain conditions, a small air bubble can be entrained in the liquid by the impacting drop and stimulated into volume pulsations ...

Identification of underwater acoustic noise
Proceedings of OCEANS'94, 2002The automatic recognition of noise situations in an underwater environment is an interesting issue, especially in coastal waters. In fact, recognition of ships by their acoustic signature captured by passive sonars can be very useful for automatic statistic tasks.

Auditory Effects of Underwater Noise in Odontocetes
2012A common result of noise exposure is a noise-induced threshold shift, defined as an increase in auditory threshold that persists after cessation of a noise exposure. If the hearing threshold returns to normal after some period of time, the threshold shift is called a temporary threshold shift (TTS).
