Dual-MIC noise reduction test device and method

Abstract

The present invention relates to a dual-MIC noise reduction test method and device, belonging to the technical field of electronic communication. The device comprises a test sound, a noise system andan artificial head. The test sound is connected with the noise system, the artificial head is provided with a mobile terminal to be tested, the test sound, the artificial head and the mobile terminalto be tested together establish a real network conversation environment, and the mobile terminal to be tested comprises a test unit. Compared to the prior art, the dual-MIC noise reduction test methodand device do not need to establish expensive high-order voice test system ACQUA test system so as to greatly reduce the test cost and save the test cost, are convenient to test with no need for reservation of a related laboratory, can perform test at any time, can clearly see which section is poor in the noise reduction effect or which section is good in noise reduction effect in the analysis software, and are convenient to analyze the test result.

Description

technical field [0001] The invention relates to a double MIC noise reduction test device and method, belonging to the technical field of electronic communication. Background technique [0002] People often need to answer calls in different environments, and some noisy environments will have a great impact on call quality, such as markets, buses, subways, roads and other places where there are many people or cars. Make it difficult for the other party to hear the voice of the person speaking. When the user is unwilling or simply unable to continue the call in this situation, typical user behavior is to end the call prematurely. On the one hand, this will lead to a direct loss of the operator's business; on the other hand, users may also mistakenly believe that it is a problem with the operator's network quality, which will lead to the loss of operators' users and damage to the product brand image; Poor, causing irreparable damage to the brand image of the manufacturer. [...

AI Technical Summary

Problems solved by technology

However, the price of this kind of test system is about 6 million yuan for the comprehensive tester + silent room, which makes this high-end voice test system expensive and the cost of equipment is high. At present, only a few companies and professional certification institutions have built this test system and environment; Moreover, irregular calibration and maintenance are required; an appointment is required during the test, which will delay the project cycle; during the test, it is not possible to directly see which section of the noise reduction effect is not good and which section of the noise reduction effect is excellent
