Noise test system and method

Abstract

The invention discloses a noise test system and method. The system includes a mute box, a digital display and a power amplifier; the mute box is parallelly arranged at one side of a production line, and includes a box body, an entrance / exit door and an observation door, the entrance / exit door is located at one side of the box body which is close to the production line, and the observation door and the entrance / exit door are oppositely arranged; both the entrance / exit door and the observation door are electric control doors, are in sliding connection with the box body, and the box body, the entrance / exit door and the observation door can form a closed chamber; the mute box is internally equipped with a noise sensor, the noise sensor is electrically connected with the digital display and an input end of the power amplifier, and an output end of the power amplifier is provided with a headset connection hole; and conveying devices are arranged at the bottom of the mute box in preset conveying positions on the production line, and the conveying direction of the conveying devices is vertical to the operating direction of the production line. The noise test system can directly and accurately reflect noise level of a product in operation, and ensures consistency of detection of product quality.

Description

technical field [0001] The invention relates to the technical field of product noise detection, in particular to a noise testing system and method. Background technique [0002] On the production line of finished air conditioners, after the scheduled assembly process is completed, an operation test is required to identify whether there is any abnormality in the finished air conditioner after assembly, including the content of the noise test. Traditional air conditioner finished product noise detection is done by manual judgment, that is, the inspector puts his ear close to the product when the product is running, and relies on his own hearing to judge whether the noise of the product meets the standards and requirements. When the finished air conditioner is in operation, there is a lot of wind blowing out, and the environment where the production line is located is complex, and there are many external interference noises, so when the human ear is close to it, it will be seri...

AI Technical Summary

Problems solved by technology

When the finished air conditioner is in operation, there is a lot of wind blowing out, and the environment where the production line is located is complex, and there are many external interference noises, so when the human ear is close to it, it will be seriously disturbed, and there is no unified evaluation standard, so it is impossible to accurately judge the noise. True level, so that it is difficult to guarantee the consistency of the quality of finished air conditioners
