Abstract:
A device for the acquisition and conditioning of a sound signal generated by a source of an internal combustion engine and comprising a box-shaped support body having a first measuring assembly and a second measuring assembly; wherein the first measuring assembly is provided with at least two first microphones which lie on a first plane and are configured for the detection of a first acoustic signal generated by the source along a first provenance direction; and wherein the second measuring assembly is provided with at least a second microphone arranged on a second plane configured for the detection of a second acoustic signal generated by the source along a second provenance direction different from the first provenance direction.
