A review of smart volume controllers for consumer electronics

This paper reviews various schemes for smart acoustic volume controllers (SVCs) for consumer electronics such as televisions, car stereo systems, CD players, AM/FM radio, telephones, mobile phones etc. There are several instances of applications of smart volume controllers in consumer electronic devices. In car stereo systems, the volume level automatically dips when the system detects the telephone ringing. The mobile with smart volume controller provides an improved speech quality even in the presence of high background noises levels. The smart volume controller for television evens out any variations in volume levels from one channel to another and program to program, thus delivering an improvement in perceived quality to the consumer. The smart volume controllers can be personalized to suit the individual´s hearing requirements. This paper also reviews several soft computing techniques for smart volume control such as fuzzy logic control, neural control, neuro-fuzzy control etc.
