PROBLEM TO BE SOLVED: To provide a control method of electronic equipment and a controller of the electronic equipment for surely detecting a noise state of the circumference of the electronic equipment and enabling a user to control to decrease erroneous operation. SOLUTION: The control method of the electronic equipment generates a plurality of band component signals by dividing voice signals based on collected sound waves into a plurality of bands. An edge pulse corresponding to generation timing of an impulse voice signal is generated on the basis of the plurality of the band component signals respectively. The edge pulse is composed in a first composition condition having a first incidence to generate a first composition edge pulse, and the edge pulse is composed in a second composition condition having a second incidence higher than the first incidence to generate a second composition edge pulse. The second composition edge pulse is determined to be in a noise state when being generated in a second number exceeding a first number of the predetermined first composition edge pulse in order to control the electronic equipment so as to generate a first noise flag.
