System and method for countering noise when operating an address system in a passenger transport

摘要

A system for countering ambient noise when operating an address system in at least one compartment of a passenger transport unit includes: (a) a noise control unit; and (b) at least one memory unit coupled with the noise control unit. The at least one memory unit stores noise characteristic information relating with at least one operational condition of the transport unit. The noise control unit employs the noise characteristic information to effect the countering.
