Open Access Peer Reviewed Research Article

Proceedings of Meetings on Acoustics

Tengjiao, H., Humphrey, V.F., Shiqi, M. and Fang, E.

Assessment of effect of Surface roughness on measured noise levels associated with shipping. Roughness reduces amplitude of coherent reflection and therefore impact of Lloyd’s mirror effect...
