    摘要: Provided are a sound source detection device (52) configured to detect sound information around an own vehicle, a sound source detection unit (1d) configured to detect a sound source around the own vehicle based on the detected sound information, an approaching vehicle determination unit (1e) configured to determine whether the sound source is a vehicle approaching the own vehicle, and a vehicle state changing unit (1i) configured to change a vehicle state of the own vehicle to a vehicle state where the own vehicle sound is able to be suppressed when an own vehicle sound generated from the own vehicle is able to be suppressed by changing the vehicle state of the own vehicle. For example, when the own vehicle is able to travel only by a power of an electric generator (12), the vehicle state changing unit (1i) is configured to suppress the own vehicle sound by changing the vehicle state of the own vehicle to a travel state where the own vehicle travels only by the power of the electric generator (12).

    摘要: The invention relates to a method for spatially filtering sound waves 2 which propagate in water and are emitted by at least one source. For this purpose, these sound waves 2 are received by a receiving arrangement 6 having a multiplicity of electroacoustic transducers 8 and corresponding reception signals 20 are formed. The reception signals 20 are used to generate a spatial energy spectrum from which significant levels p(i) are selected for each control direction i to be considered. A signal model matrix
    R
    M is determined from an antenna response a(
    k ) associated with the receiving arrangement 6 and from the selected levels p. A source control vector
    a
    Source
    (k) which optimally suppresses all significant sources is then determined from this signal model matrix
    R
    M and from the antenna response a(
    k ). A check is also carried out in order to determine whether there is a source in the control direction (i) to be considered
    . If this is the case, a filter control vector
    a
    Filter
    (k) is determined from the signal model matrix R
    M and from the antenna response a(
    k ) for this control direction i. However, if no source is determined in the control direction i to be considered, the filter control vector
    a
    Filter
    (k) corresponds to the source control vector
    a
    Source
    (k) , as a result of which the secondary levels are optimally suppressed. The filter control vector determined in this manner can be used to spatially filter the sound waves 2 emitted by a source. The invention also relates to a corresponding apparatus for carrying out the method.

    摘要: Das Verfahren ist zur Erfassung und Ortung von Geräuschemissionen bewegter Objekte in Form von U-Booten (10) unter Wasser, bestimmt. Es werden mit einer Vielzahl von mit Abstand nebeneinander und übereinander und im Wesentlichen in einer Ebene angeordneten Hydrophonen (7) Schallwellen des quer zu dieser Ebene verfahrenen Objektes (10) erfasst und registriert, wobei anhand der zeitlichen Korrelation der erfassten Schallwellen eine räumliche Zuordnung der Schallemission erfolgt.
