Bioacoustics is a cross-disciplinary science, which investigates sound production and reception in animals, the biological acoustically-borne information transfer and its propagation in elastic media. Bioacoustics also refers to the organs of hearing and to the sound production apparatus, as well as to the physiological and neurophysiological processes by which sounds are produced, received and processed. Furthermore, bioacoustics attempts to understand the relationships between the features of the sounds an animal produces and the nature of the environment in which they are used, as well as the functions they are designed to serve. Finally, it includes the techniques associated with instrumental and biological sonar for its use in population monitoring, identification and communication encoding mechanisms and allows the assessment and control of the effects of human-made noise on animals.

The creation of the Laboratory of Applied Bio-Acoustics (LAB) at the Technical University of Catalonia, BarcelonaTech (UPC) is the necessary and mature response of a multi-disciplinary group of scientists to the increasing acoustic degradation of the marine habitat.

The LAB has the clear objective to respond with technological solutions to the progressive deterioration of the seas, limiting the effects of anthropogenic noise and contributing to the sustainable development of human marine activities. The research outcome is answering the increasing demand from local, national and European administrations and from the society itself, by providing the necessary expertise on the control mechanisms and a better understanding of the marine noise pollution.
