Abstract:
1. A sensor system designed to be located in an environment composed of a first medium, where waves propagate with a first phase velocity, the sensor system comprising at least one main enclosure and a sensor array with at least two sensors, said sensor array being arranged inside the main enclosure, wherein the first medium is air and the space inside the main enclosure between the sensor array and the inner surface of the main enclosure is filled with a second medium, in which waves propagate with a second phase velocity, wherein the second medium is of such a kind that the second phase velocity of waves propagating in the second medium is lower than the first phase velocity of waves propagating in the first medium, wherein the sensors of the sensor array are acoustic sensors, wherein MEMS (Micro-electro-mechanical Systems) microphones are used for the acoustic sensors.
