A 10 dB increase in volume will result in a perceived doubling of loudness. Therefore, the family will perceive the music as 2 times louder than before. Option A is not correct as a 10 dB increase corresponds to a 10-fold increase in sound intensity, not perceived loudness. Option B is not correct as a 100 dB increase would be required for a 100-fold increase in perceived loudness. Option D is not correct as the loudness would have increased, albeit not by a significant amount.
