In this article we explain how it is possible to record sound pressure and particle velocity together underwater, thanks to an old theory developed in the seventies. Most studies made in the past on the effect of environmental noise pollution and on the sensitivity of marine species to underwater noise were, in fact, substantially wrong: limits specified only for sound pressure caused a systematic underestimation of the potential impact of noise, strongly biasing results.

Abstract
In this article we explain how it is possible to record sound pressure and particle velocity together underwater, thanks to an old theory developed in the seventies. Most studies made in the past on the effect of environmental noise pollution and on the sensitivity of marine species to underwater noise were, in fact, substantially wrong: limits specified only for sound pressure caused a systematic underestimation of the potential impact of noise, strongly biasing results.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
