Abstract

The invention discloses a method and a device for regulating volume, and a digital terminal. The method comprises the following steps of: acquiring sounds in a peripheral environment, and extracting a characteristic frequency spectrum of the sounds; comparing the characteristic frequency spectrum of the sounds in the peripheral environment with a preset noise characteristic frequency spectrum library, and judging whether the sounds are noise or not; if the sounds in the peripheral environment are noise, measuring and acquiring a decibel value of the sounds in the peripheral environment by the terminal; calculating and acquiring a volume value which is suitable for an environment according to the decibel value of the sounds; and regulating the volume of the terminal according to the acquired volume value which is suitable for the environment. The invention also discloses the device for implementing the method and the digital terminal.

Description

technical field

[0001] The present invention relates to the technical field of digital terminals, in particular to a method and device for adjusting volume and a digital terminal. Background technique

[0002] The current method for adjusting the volume of terminals such as televisions is mainly to control the size of the volume through artificial setting by the operator. When the sound of the external environment changes and affects the effect of watching TV, the user can only adapt to the change of the environment by resetting the control parameters, which requires constant operation of the remote controller to adjust the volume, which is very inconvenient.

[0003] AVC (automatic volume control), the current technology for automatic volume control of TVs, is mainly aimed at automatically adjusting the volume of the internal sound signal of the TV, and is not suitable for volume adjustment when the sound of the external environment changes.
