Problems solved by technology

Operators generally have no background technology in acoustics, and often do not know how to choose
If the selection is not made in the correct order, it will often lead to wrong calibration results, which is very dangerous in the quality control of factory products

Embodiment Construction

[0019] The present invention will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0020] Such as figure 1 As shown, a calibration method for an audio measurement and control system includes the following steps:

[0021] Step 1: The audio measurement and control system searches for the current test settings, and automatically performs microphone test system calibration or speaker test system calibration according to the test settings. For example: the last time the audio measurement and control system did a microphone test, the audio measurement and control system automatically calibrates the microphone test system (that is, the second and third steps in turn); the last time the audio measurement and control system did a speaker test, the audio The measurement and control system automatically calibrates the speaker test system (that is, performs the fourth step). Or the audio measurement and control system...

Abstract

The invention discloses a method for calibrating an audio measurement and control system, which comprises the following steps: searching the current test configuration and automatically performing calibration on a microphone test system or a loudspeaker test system. The calibration on the microphone test system comprises the following steps sequentially: calibrating a reference microphone to obtain the sensitivity of the reference microphone; and calibrating an artificial mouth to calibrating the sound pressure level of the artificial mouth to a preset range. The method does not need an operator to judge calibration items to be carried out currently or know well about an acoustic product or an acoustic instrument. The method is simple and convenient to use. The calibration on the microphone test system comprises performing the calibration on the reference microphone at first automatically and then performing the calibration on the artificial mouth, and does not need the operator to perform the selection between the calibration on the reference microphone and the calibration on the artificial mouth, thus the accuracy of the calibration result is ensured and the quality management and control quality of a factory product is provided.

Description

technical field [0001] The invention relates to a calibration method for an audio measurement and control system. Background technique [0002] The existing audio measurement and control system is divided into two categories according to the control type: one is the audio analyzer based on programmable control, and the other is the audio tester based on traditional manual operation. With the help of the powerful control capability of the computer, the programmable audio analyzer automatically performs parameter configuration, data collection and simple analysis on the instrument itself after receiving the software control command through the data line, and sends the analysis results to the software through the data line for further analysis. Further complex analysis and processing. [0003] The audio measurement and control system developed based on the programmable audio analyzer generally has the problem of complex operation. The existing calibration method of the audio ...
