Disclosed is a method for detecting an acoustic event of interest in a space. In the method acoustic signal data is obtained from sensors and at least some candidate impulses are determined. The candidate impulses are mapped to a representation on a basis of an origin of the candidate impulse in question and it is determined, from the generated representation, at least one indication quantity representing a likelihood of an acoustic event of interest taking place in the specified positions in space and time. Finally, the at least one indication quantity is compared to a predetermined threshold and an indication is generated if the at least indication quantity meets the predetermined threshold. Also disclosed is a computing unit and a computer program product.
