Active control of vessel navigation noise´s specific linear spectrum

The problem of active controlling vessel navigation noise´s specific linear spectrum in one dimension zone is investigated. The relationship between noise control result, the relative position of sound source and receiver is identified by simulation. Finally an active noise reduction method relying on and estimation of the relative position between the vessel and the receiver is proposed. The method focuses on reducing vessel navigation noise´s specific spectrum, which are in the low frequency band and have largest impact on marine animals.
