ABSTRACT:
In an automatic loudness compensator provided in a sound reproduction device in a vehicle, the sound level is compensated to reproduce a sound source with the high fidelity intended by the producer of the source of sound. The level of sound frequency-pressure is increased or decreased relative to a middle range of sound frequency at a sound level lower or higher than a reference sound level, respectively. The level of sound frequency-pressure is also adjusted based on the noise produced by the movement of the vehicle and on the acoustic characteristic of the passenger compartment of the vehicle.
