An audio device maintenance support apparatus which is capable of notifying a user in advance of timing for loudspeaker unit replacement. An audio signal is input via a signal input section. An amplifier amplifies the input audio signal. A loudspeaker unit outputs the audio signal amplified by the amplifier, as sound. An integral value calculating section calculates an integral value of the signal level of the audio signal supplied to the loudspeaker unit via the amplifier with respect to a supply time length of the audio signal. When the calculated integral value exceeds a predetermined threshold value, a notification control section gives a message recommending maintenance of the loudspeaker unit.
