Abstract
A method for determining a status of a microphone comprises inducing a piezoelectric component, located in a vicinity of and in mechanical connection with the microphone, to emit a predetermined impulse waveform; determining whether a response signal waveform from the microphone corresponds to the predetermined impulse waveform; and upon the response signal waveform from the microphone corresponding to the predetermined impulse waveform, determining that the status of the microphone is operational.
Claims11
A method for determining a status of a microphone, the method comprising:
- registering an audio signal from the microphone and providing the audio signal to an audio signal receiver;
- providing, while registering the audio signal from the microphone and while providing the audio signal to an audio signal receiver, a temporary replacement audio signal to the audio signal receiver;
- transmitting a predetermined impulse waveform to a piezoelectric component, the piezoelectric component being located in a vicinity of the microphone and arranged in mechanical connection with the microphone, to induce a mechanical impulse in the piezoelectric component;
- determining whether a response signal waveform from the microphone corresponds to the predetermined impulse waveform;
- resuming the provision of the audio signal to the audio signal receiver, and
- upon the response signal waveform from the microphone corresponding to the predetermined impulse waveform, determining that the status of the microphone is operational.
