During driving, noise in the car changes according to the driving
speed and road conditions. ASL (automatic sound levelizer)
monitors such varying noise and automatically increases the
volume level, if this noise becomes greater. The sensitivity
(variation of volume level to noise level) of ASL can be set to one
of five levels.
