Abstract

The invention provides an automatic volume adjusting system and method for multimedia terminal equipment. The system comprises a data processing center, a multimedia sound source module, an ambient sound sampling module and a multimedia playing module, wherein the multimedia sound source module, the ambient sound sampling module and the multimedia playing module are independently connected with the data processing center. According to the invention, the data processing center and the environment sound sampling module are arranged to form the audio playing feedback system. The data processing center extracts and compares the environment sound audio feature information with the sound source sound feature information according to the dynamic volume balance calculation module and the human auditory simulation calculation module, and compares the simulated human ear perception volume with the user set volume. According to the method, the volume is adjusted in real time according to the noise change condition in the environment, the space change of the environment and other factors, the adaptive adjustment of the volume is achieved, the human ear hearing is reduced. The working pressureof nerve analysis is reduced. The dual effects of auditory system protection and listening experience optimization are achieved, and real adaptive volume balance can be provided for a user.

Description

technical field [0001] The invention relates to the technical field of volume adjustment, in particular to a system and method for automatic volume adjustment of multimedia terminal equipment. Background technique [0002] The volume adjustment methods of existing multimedia terminal equipment are mostly touch screen control or button control, but this volume control method requires manual processing by the user. Adaptive volume adjustment. In addition, in noisy environments, such as public places such as bus stations and train stations, or houses on both sides of the road, sudden external noise may also make users unable to hear the specific content of multimedia terminal devices such as movies and TV programs. [0003] In view of the above scenarios, Sony, Apple, Dolby and other companies have conducted research on the automatic adjustment of multimedia volume, and designed a Dynamic Normalizer technology based entirely on the statistics of sound sources based on software...
