The invention provides a method for quickly adjusting microphone gain and detecting microphone floor noise. The method comprises the following steps: equipment is started and recording is started; a tester plays the start marking record and the 95dBA powder noise test record; the equipment detects a start mark in the voice data and starts to automatically adjust the gain of the microphone; after the broadcast gain of the equipment is adjusted, a background noise detection stage is entered; after a tester manually seals the microphone, the start mark record is played; after the equipment detects the start mark in the voice data, it is started to detect microphone bottom noise; and the equipment counts and broadcasts the background noise mean value. According to the method provided by the invention, gain adjustment and bottom noise test can be completed at one time, test records do not need to be played back and forth and microphone records do not need to be analyzed, and the test time and cost are saved; and the test software is utilized to automatically complete most tests and statistics, so that manual intervention is reduced, and the complexity and error probability of operation are reduced.
Description
technical field [0001] One or more embodiments of the present invention relate to the technical field of signal processing, and in particular, to a method for quickly adjusting microphone gain and detecting microphone floor noise. Background technique [0002] This section is intended to provide a background or context for implementations of the invention that are recited in the claims. The descriptions herein may include concepts that could be explored, but not necessarily concepts that have been previously thought of or explored. Therefore, unless otherwise indicated herein, what is described in this section is not prior art to the description and claims in this application and is not admitted to be prior art by inclusion in this section. [0003] The noise floor of the microphone refers to the self-noise noise energy of the equipment that can be detected in the recording data due to the design defects of the microphone itself or the circuit when the microphone circuit re...
