Problems solved by technology

However, when people enjoy audio-visual entertainment, they will inevitably encounter a problem: the environmental noise
Especially some low-end speakers and other sound playback equipment will produce broken sound when the volume is high, thus destroying the playing environment and atmosphere
[0006] (2) Excessive volume can damage people's health
[0007] (3) Excessive volume becomes noise in turn
When the volume of the playback device is too high, it may affect others
[0008] (4) In addition, when the noise level of the surrounding environment changes, the user may need to manually adjust the volume in real time
[0009] Due to the above problems, it is not advisable to blindly increase the volume to overcome the influence of noise when playing in a noisy environment
[0010] It can be seen that in a noisy environment, increasing the volume to play audio and video requires the user to manually adjust the volume in real time according to the noise level, so that the user cannot perform other services at the same time, the sound effect is not good, and the volume is too high

Abstract

This invention discloses one method and device based on environment noise test and volume adjusting, which comprises the following steps: presetting play volume zone or value range; storing play audio wave data and collected outer audio wave data; comparing the data and then comparing the result with preset play volume zone value range; adjusting the volume according to compare result.

Description

Technical field [0001] The present invention relates to player technology, in particular to a method and device for realizing volume adjustment based on environmental noise detection. Background technique [0002] With the rapid development of computer and multimedia technology, as well as the continuous improvement of people’s quality of life, enjoying audio-visual entertainment all the time and everywhere has become a goal pursued by the public. Some European and American scholars have even put forward the "Ubiquitous Entertainment" (nowhere Entertainment and leisure when absent). However, when people enjoy audio-visual entertainment, they will inevitably encounter a problem: environmental noise. Such as: the sound of various equipment in the office, the ringing of telephones one after another; the noise of people in entertainment places; the noise of urban traffic and roads. The World Health Organization has recently conducted an analysis and investigation on the noise polluti...
