<p>A sound volume control device (1) includes a sound input section (11), a band dividing section (12), an excessive output notification section (13), a correction band decision section (14) and a sound output control section (15). The sound input section (11) converts input sound into a sound signal (S1). The band dividing section (12) carries out band-division with respect to the sound signal (S1). The excessive output notification section (13) outputs excessive output notification information (S3) when output sound from the present device (1) is excessive. The correction band decision section (14) calculates audible signal distribution information (S4) when the excessive output notification information (S3) is not output and excessive signal distribution information (S5) when the excessive output notification information (S3) is output, for each band in the sound signal, and decides a correction band according to the audible signal distribution information (S4) and excessive signal distribution information (S5). The sound output control section (15) controls sound volume of sound signal for the correction band to provide output sound.</p> |
