An apparatus for performing a medical procedure is disclosed. The apparatus includes a sensor adapted to convert an ultrasonic signal incident thereon into an electrical signal; and a wireless transceiver configured to receive the electrical signal from the sensor, and to transmit the electrical signal to a wireless receiver remotely located from the apparatus.

It is provided a system for localizing a sound source and a method therefor. The system includes a movable unit, being adapted for free movement and being integrated with a microphone; a motion tracking unit; and a processing unit, being adapted for receiving microphone signal and motion tracking unit signal and obtaining information on a direction from which sound from the sound source arrives using the microphone signal and motion tracking unit signal obtained during movement of the movable unit. By having the system and the method therefor, it is helpful for solving at least one of the technical problems: the complexity and a large volume of an acoustic camera for localization of a sound source; the restriction of the movement of the microphone in a sound source localization system.

An apparatus comprising at least one first microphone (10) which is movably arranged, at least one second stationary microphone (11) and at least one sensor (16) is described. The microphones can capture the sound waves emitted by acoustic sources, and the sensor can capture spatial coordinates of the first microphone. A corresponding method and a system having the apparatus mentioned are also described.
