ABSTRACT:
According to one embodiment, an acoustic apparatus comprises a measuring signal generator, a transducer configured to convert a measuring signal to a measuring sound and to convert a characteristic vibration of the transducer due to the measuring sound, to a characteristic vibration signal, an analysis module configured to analyze the characteristic vibration signal in order to output a physical quality of a characteristic vibration of the transducer, a controller configured to set a first state in which the transducer converts an electric signal to an acoustic signal or a second state in which the transducer converts an acoustic signal to an electric signal. The measuring signal generator is connected to the transducer in the first state and the analysis module is connected to the transducer in the second state.
