The invention discloses a decibel value reference interval determination method for automatic detection of a loudspeaker and a microphone, a method for automatic detection of the loudspeaker and the microphone and a storage medium. The interval determination method comprises the following steps: enabling normal electronic equipment to be in a quiet test environment, outputting a test audio through a loudspeaker, enabling a microphone to carry out sound acquisition, determining a decibel value of audio data acquired by the microphone, and taking the decibel value as a lower limit reference decibel value; the method comprises the following steps: enabling normal electronic equipment to output a test audio through a loudspeaker and enable a microphone to carry out sound acquisition in a noisy test environment with the noise being a preset maximum value, determining a decibel value of audio data acquired by the microphone, and taking the decibel value as an upper limit reference decibel value; and a decibel value
