Claim 0:
1. An in-car adaptive sound quality output method, including steps of:
obtaining a current volume level entered by the user;
determining an audio signal gain difference between the current volume level and a baseline volume level according to the current volume level and a preset baseline volume level,
determining an equal loudness curve difference between the current volume level and the baseline volume level according to the audio signal gain difference, the current volume level and the baseline volume level;
determining an audio quality response curve corresponding to the current volume level according to the equal loudness curve difference and the pre-stored audio quality response curve corresponding to the baseline volume level; and
determining an output signal parameters of multiple audio output channels according to the audio quality response curve corresponding to the current volume level.
