. By the end of 2017, the IOA counts more than 700 researchers focusing on the study of basic and applied acoustics, in the following fields: #

Underwater acoustics Underwater acoustics (also known as hydroacoustics) is the study of the propagation of sound in water and the interaction of the mechanical waves that constitute sound with the water, its contents and its boundaries. The water may be in the oce ...

and underwater acoustical detection; # Environmental acoustics and noise control technologies; #

Ultrasonics Ultrasound is sound with frequency, frequencies greater than 20 Hertz, kilohertz. This frequency is the approximate upper audible hearing range, limit of human hearing in healthy young adults. The physical principles of acoustic waves apply ...
