Abstract
An adaptive audio control method based on scenario identification includes: acquiring acceleration data of a user, and analyzing a use scenario of the user according to the acceleration data; acquiring an ambient sound signal of the surrounding environment of the user, calculating a sound level intensity of the ambient sound signal, and analyzing an energy and a spectral distribution of the ambient sound signal; and controlling, according to the use scenario, the sound level intensity of the ambient sound signal, and the energy and the spectral distribution of the ambient sound signal, an audio signal volume, and an active noise cancellation level, and regulation of the ambient sound signal of an audio playback device. The method further enables acquisition of geographic location data of the user and uses the same, as well as acceleration data, for analysis of the use scenario of the user.
