SOUND BAFFLE DEVICE AND SYSTEM FOR DETECTING ACOUSTIC SIGNALS

摘要

A sound baffle device for use with an acoustic sensor deployed in a housing by a deployment line is disclosed. The sound baffle device comprises a radially extending baffle plate and an affixing mechanism for affixing the baffle plate to the deployment line. The baffle plate is configured to reduce acoustic transmission between a first zone of the housing on one side of the baffle plate and a second zone of the housing on an opposite side of the baffle plate. A system for detecting acoustic signals in a zone of interest in a housing is also disclosed. The system comprises an acoustic sensor positioned in the zone of interest and one or more than one sound baffle positioned between the zone of interest and a first zone of the housing. The sound baffle is configured to reduce acoustic transmission from the first zone to the zone of interest. The sound baffle provides some level of acoustic isolation between two zones on either side of the baffle plate thereby aiding detection and identification of acoustic signals in the zone of interest by reducing transmission of acoustic signals from the first zone to the zone of interest.
