A sound or vibration source localization system with a master unit and a plurality of slave units. The master unit transmit a time synchronization signal via an RF link to the slave units. A microphone or vibration sensor in each of the slave units are used to record a short time sequence, e.g. 0.2-2 seconds, of sound or vibration time aligned with the time synchronization signal to ensure synchronous recording of the time sequences at all slave units. The slave unit transmit the recorded time aligned time sequences via an RF link along with a time stamp and an identification code to the master unit. The master unit has a processor system arranged to process the received time sequences from the slave units according to a lizard ear mimicking algorithm. Such type of algorithm provides a good direction estimate in response to two input signals recorded at different positions, even with a short time sequence. As a result, and preferably along with information regarding physical positions of the slave units, a sound source or vibration source localization estimate can be generated.
