Verfahren und Vorrichtung zur Unterscheidung informationshaltiger akustischer Signale,insbesondere Navigationssignale,gegenueger Hintergrundgeraeusch

摘要

A hearing lookout assist device improves the contrast between meaningful marine navigation sounds and the ship's background noise sound, such as own ship bow wake and machinery noise. The frequency response of the listening device is arranged to maximize response of the lookout's hearing to desired navigational sounds and to minimize the masking and other deleterious effects of objectionable interfering noise sound energy.
