Project Description :
It is of great interest to understand how well sound from an acoustic source (e.g. human voice) in air can propagate into water. In this project, both theoretical simulation and hands-on experiments will be carried out to understand the effects of the sound propagation from air to water medium.

For the simulation study, simple models such as ray tracing can be developed to understand the physics and principle of the sound propagation from air to water. Alternatively, other simulation model (available in DSO) can be used to study this air-to-water propagation effects.

To verify the simulation study, experiments will be carried out in a swimming pool environment (eg. at NTU pool). Sound transmitted by a loud speaker in air will be measured both in air and water during the experiments. Hands-on experiences on using acoustic and underwater sensors and other measurement equipments will be acquired by the student. Data analysis and comparison between the simulation and experimental results will also be conducted.
