[HTML][HTML] Measuring vessel underwater radiated noise in shallow water
AO MacGillivray, SB Martin, MA Ainslie… - The Journal of the …, 2023 - pubs.aip.org
Performing reproducible vessel source level (SL) measurements is complicated by seabed
reflections in shallow water. In deep water, with a hydrophone far from the seabed, it is
straightforward to estimate propagation loss (PL) and convert sound pressure level (SPL)
into SL using the method codified in the international standard ISO 17208-2 [International
Organization for Standardization (ISO), Geneva, Switzerland (2019)]. Estimating PL is more
difficult in shallow water because of the way that sound reflects from the seabed such that …
