PROBLEM TO BE SOLVED: To provide an electronic volume switching device capable of reducing the generation of noises in switching the volume. SOLUTION: When an attenuation coefficient inputted to a coefficient interpolation part 13 is switched by an operator's operation, the electronic volume switching device 1 for switching the volume of an output sound signal by switching an attenuation coefficient inputted to an attenuator 22 interpolates attenuation coefficients obtained before and after switching and successively provides attenuation coefficients to be gradually transited to the coefficient after switching to the attenuator 22. Even when the number of switching steps of the volume is comparatively small, noise generation in switching volume can be reduced.
