The human contribution to ambient noise in the ocean has increased over the past 50 years, and is dominated by low-frequency (LF) sound (frequencies <1000 Hz)...

The construction of the Horns Rev II wind farm is accompanied by a marine mammal monitoring programme. As a part of that study, underwater noise was...

Marine mammals, especially cetaceans, are highly vocal and dependent on sound for almost all aspects of their lives, e.g. food-finding, reproduction, communication, detection of predators/hazards, and...

Studies on the effects of offshore wind farm construction on marine life have so far focused on behavioural reactions in porpoises and seals. The effects on...

In seismic surveys, underwater sounds from airguns are used to detect rocks that may contain gas and oil below the sea floor. Airguns produce broadband high-amplitude...

The key to an ultimately useful risk assessment methodology is ease of use in the face of data limitations, production of reasonable predictions that fit available...

Standard audiometric data are often applied to predict how noise influences hearing. With regard to auditory masking, critical ratios—obtained using tonal signals and flat-spectrum maskers—can be...

A literature review, internet searches, and communications with personnel working with unmanned aerial systems (UAS) were used to identify the capabilities of UAS throughout the world....

Ringed seals (Pusa hispida) are semi-aquatic marine mammals with a circumpolar Arctic distribution. In this study, we investigate the amphibious hearing capabilities of ringed seals to...

Underwater hearing thresholds were measured at 100 Hz in trained spotted (Phoca largha) and ringed seals (Pusa hispida) before and immediately following voluntary exposure to impulsive...
