Abstract
An example apparatus for detecting loudspeaker faults includes a switch detector to detect that a loudspeaker fault detection switch is enabled. The apparatus also includes an audio receiver to receive an echo energy threshold and audio from a microphone in a test area. The apparatus further includes an audio analyzer to detect that the echo energy threshold is not exceeded by an acoustic echo in the captured audio. The apparatus includes a fault generator to generate a loudspeaker fault in response to detecting the acoustic echo does not exceed the echo energy threshold.
Claims23
An apparatus for detecting loudspeaker faults, comprising:
- a switch detector to detect that a loudspeaker fault detection switch is enabled;
- an audio receiver to receive an echo energy threshold and audio from a microphone in a test area;
- an audio analyzer to detect that the echo energy threshold is not exceeded by an acoustic echo in the captured audio;
- a fault generator to generate a loudspeaker fault in response to detecting the acoustic echo does not exceed the echo energy threshold;
- and
- a backup activator to activate a backup response system comprising an automated braking system or an automated lane change system in response to detecting the loudspeaker fault.
A method for detecting loudspeaker faults, comprising:
- detecting, via a processor, an enabled loudspeaker fault detection switch;
- receiving, via a microphone in a test area, audio;
- detecting, via the processor, an acoustic echo in the captured audio does not exceed an echo energy threshold;
- generating, via the processor, a loudspeaker fault in response to detecting the acoustic echo does not exceed the echo energy threshold and the loudspeaker fault detection switch is enabled;
- and
- activating, via the processor, a backup response system comprising an automated braking system or an automated lane change system in response to detecting the loudspeaker fault.
At least one non-transitory computer readable medium for detecting loudspeaker faults having instructions stored therein that, in response to being executed on a computing device, cause the computing device to:
- detect that a loudspeaker fault detection switch is enabled;
- receive audio from a microphone in a test area;
- detect that an acoustic echo in the captured audio does not exceed an echo energy threshold;
- generate a loudspeaker fault in response to detecting that the loudspeaker fault detection switch is enabled, that the acoustic echo does not exceed the echo energy threshold, and that an output channel contains audio;
- and
- activate a backup response system comprising an automated braking system or an automated lane change system in response to detecting the loudspeaker fault.
