Abstract
A method performed by a processor of an audio source device. The method drives an audio output device of the audio source device to output a sound with an audio output signal. The method obtains a microphone signal from a microphone of the audio source device, the microphone signal capturing the outputted sound. The method determines whether the audio output device is a headset or a loudspeaker based on the microphone signal and configures an acoustic dosimetry process based on the determination.
Claims21
A method performed by a processor of an audio source device, the method comprising:
- driving an audio output device of the audio source device to output a sound with an audio output signal;
- obtaining a microphone signal from a microphone of the audio source device, the microphone signal capturing the sound output;
- determining whether the audio output device is a headset or a loudspeaker based on the microphone signal;
- responsive to determining that the audio output device is a headset, configuring an acoustic dosimetry process for the headset;
- and
- responsive to determining that the audio output device is a loudspeaker, configuring an acoustic dosimetry process for the loudspeaker.
An audio source device, comprising:
- a microphone;
- a processor;
- and
- a memory having stored therein instructions which when executed by the processor cause the audio source device to
- drive an audio output device to output a sound with an audio output signal;
- obtain a microphone signal from the microphone, the microphone signal capturing the sound output;
- determine whether the audio output device is a headset or a loudspeaker based on the microphone signal;
- responsive to determining that the audio output device is a headset, configure an acoustic dosimetry process for the headset;
- and
- responsive to determining that the audio output device is a loudspeaker, configure an acoustic dosimetry process for the loudspeaker.
A processor of an audio source device that is configured to:
- drive an audio output device of the audio source device to output a sound with an audio output signal;
- obtain a microphone signal from a microphone of the audio source device, the microphone signal capturing the sound output;
- determine whether the audio output device is a headset or a loudspeaker based on the microphone signal;
- responsive to determining that the audio output device is a headset, configure an acoustic dosimetry process for the headset;
- and
- responsive to determining that the audio output device is a loudspeaker, configure an acoustic dosimetry process for the loudspeaker.
