Update Noise Regulations to Protect Seals, Porpoises
In The Journal of the Acoustical Society of America, scientists in Denmark review recent experiments and find noise regulations may need to be changed to protect porpoises, seals, and other sea-dwelling mammals. Current guidance for seals and porpoises is based on few measurements in a limited frequency range; the guidance is still valid for these frequencies, but investigators found substantial deviations in recent studies of the impact of low frequency noise on seals and high frequency noise on porpoises.
