Abstract

The invention relates to the field of function testing, and in particular relates to a testing method for a noise reduction function of a device and the relevant device. The testing method for the noise reduction function of the device comprises the following steps: acquiring performance parameters of a to-be-tested device, and establishing a testing scene of the to-be-tested device according to the performance parameters; acquiring parameters of the testing scene, according to the parameters of the testing scene, extracting any original sound corresponding to the parameters of the testing scene from a preset sound library, and according to the differences between a sound wave curve of the original sound and a preset sound wave curve, correcting the original sound, so that a sound sample is obtained; and inputting the sound sample into the to-be-tested device, carrying out playing through the to-be-tested device, receiving the played sound sample, thus obtaining a testing sample, comparing the testing sample with the sound sample, and generating a noise reduction testing report according to the comparing result. The evaluation index for testing the noise reduction function is increased, the testing dimensionality is expanded, the testing efficiency is promoted, and the automatic testing can easily access in quality testing.

Description

technical field [0001] The present application relates to the technical field of function testing, in particular to a method for testing the noise reduction function of equipment and related equipment. Background technique [0002] People often use mobile phones, computers and other devices to listen to music, video calls, voice calls, etc., and the requirements for the noise reduction function of these devices are also getting higher and higher. The main noise reduction technology used in mobile phones is dual-mic noise reduction. One microphone is used by ordinary users to collect human voices during calls, and the other is a microphone configured on the top of the fuselage. It has the function of collecting background noise, which is convenient Collect ambient noise. The lower microphone is mainly used to pick up the speaker’s voice and is called the main microphone. The upper microphone is used to pick up background noise and is called the secondary microphone. The soun...
