Audio processing device capable of dynamically adjusting basis for calculating audio dose

An audio processing device (100), comprising:

• an audio playback device (120), arranged to operably generate sound based on an audio configuration signal (ACS);
• and
• an audio dose monitoring circuit (110), comprising:
• a sound level measuring circuit (111), arranged to operably generate multiple sound level values (SVs) respectively corresponding to multiple sound levels based on the audio configuration signals (ACSs), wherein the multiple sound levels are generated by the audio playback device (120) at multiple time points;
• an audio dose calculating circuit (113), coupled with the sound level measuring circuit (111), and arranged to operably generate an audio dose value (AD) corresponding to a measuring period based on the multiple sound level values (SVs) and contents of a weighting table (200;
• 400;
• 500;
• 600);
• a control circuit (116), coupled with the audio dose calculating circuit (113), and arranged to operably generate the audio configuration signal (ACS), and to operably compare the audio dose value (AD) with a dose threshold to determine whether to generate a control signal (CTL) or not;
• and
• an indication signal generating circuit (114), coupled with the control circuit (116), and arranged to operably generate a corresponding indication signal (INS) according to the control signal (CTL).
