Contact Hours:

2.0

Lecture:

2 x 1 Hours Weekly

Syllabus:

Basic concepts of sound propagation. Field trip - Canning River - noise measurements, tone source measurements using different tone frequencies, towing experiment to observe the variations of sound level with changing distance between the source and receivers. Device for generating and receiving sound in water. Noise in the ocean. Ray acoustics, principles of refraction. Deep water propagation. Wave acoustics. Shallow water acoustics. Bioacoustics - sound production and reception and use of sound by marine animals. Impact of anthropogenic noise on marine animals. Applications to environmental assessment and marine resource estimation. Defence applications of marine acoustics. Commercial applications of underwater acoustics.

Unit Outcomes:

On successful completion of this unit students will have an understanding of the general principles of sound production, propagation and reception underwater and be able to describe how these principles are applied by humans and marine animals.
