open-in-new
<p>In <a href="/facts/Underwater_acoustics/jtz7GLNa">underwater acoustics</a>, propagation loss is a measure of the reduction in <a href="/facts/Sound_intensity/c9KFwjYL">sound intensity</a> as the sound propagates away from an underwater sound source. It is defined as the difference between the source level and the received <a href="/facts/Sound_pressure_level/MgJAcp2I">sound pressure level</a>. </p>
