LOUDSPEAKER NOISE INSPECTION METHOD, LOUDSPEAKER NOISE INSPECTION DEVICE AND RECORDING MEDIUM FOR RECORDING A LOUDSPEAKER NOISE INSPECTION PROGRAM

摘要

A loudspeaker noise inspection method is to be implemented by an electronic device and includes the steps of: obtaining a frequency sweeping audio signal from an audio output generated by a loudspeaker in response to a frequency sweeping input signal; performing differentiation upon the frequency sweeping audio signal so as to generate a differentiated frequency sweeping audio signal; and dividing the differentiated frequency sweeping audio signal by a constant which is greater than 2π times a maximum frequency of the frequency sweeping audio signal, so as to obtain an attenuated frequency sweeping audio signal for inspection of a noise pulse in the frequency sweeping audio signal.

1. A loudspeaker noise inspection method, the method to be implemented by an electronic device and comprising the steps of:
(A) obtaining, using the electronic device, a frequency sweeping audio signal from an audio output generated by a loudspeaker in response to a frequency sweeping audio input signal; (B) performing, using the electronic device, differentiation upon the frequency sweeping audio signal so as to generate a differentiated frequency sweeping audio signal; and (C) dividing, using the electronic device, the differentiated frequency sweeping audio signal by a constant which is greater than 2π times a maximum frequency of the frequency sweeping audio signal, so as to obtain an attenuated frequency sweeping audio signal for inspection of a noise pulse in the frequency sweeping audio signal.
