Problems solved by technology

The user talks while walking on the street. When there are many people on the street and the noise is loud, the user needs to manually adjust the volume of the earpiece to the maximum to hear the content of the call clearly. When the user moves from a noisy place to a quieter place , it will appear that the ears are uncomfortable due to the excessive volume of the earpiece, and it will cause hearing damage in the long run.
At present, there is no technology that can effectively solve the problem of poor experience of the receiver in a noisy environment

Abstract

The present invention relates to a method and system for dynamically adjusting the call volume by using a noise reduction microphone. Detect the ambient noise value within the set time, and calculate the average value of the ambient noise within the set time; determine the ideal call volume corresponding to the average value of the environmental noise according to the preset corresponding relationship; automatically adjust according to the ideal call volume The earpiece of the calling terminal outputs volume. The present invention collects environmental noise through the self-provided noise reduction microphone of the communication terminal without adding additional hardware, and dynamically adjusts the output volume of the earpiece according to the strength of the noise, and avoids the surrounding noisy environment without manual intervention by the user The impact on the call quality, so as to meet the user's normal call needs in both quiet and noisy environments.

Description

technical field [0001] The present invention relates to the technical field of call terminal processing, in particular to a method and system for dynamically adjusting call volume by using a noise reduction microphone. Background technique [0002] Current smartphones are generally equipped with noise-canceling microphones, which can be used to process the background noise of the sender during a call through technical means, thereby improving the quality of the call. However, if the background noise of the receiving party is relatively large during the call, even if the sending party has performed noise reduction processing, it is difficult to hear the content of the call, and the user can only manually increase the output volume of the earpiece. In many scenes, background noise changes in real time, such as streets. The user talks while walking on the street. When there are many people on the street and the noise is loud, the user needs to manually adjust the volume of the...
