The use of sound output to present information is an active area of research. Sound is used in a range of devices from desktop computers, personal digital assistants and mobile telephones, to domestic appliances such as Radio, Televisions etc.,One major problem with all such devices is that the sounds are often played at the wrong volume. The manufacturers do not know the ambient noise levels of the environments where devices will be used and so take a ‘better safe than sorry’ approach and make sounds loud. Excessive loudness of sounds is a major cause of annoyance. Alternatively, in very loud environments sounds may be played too quietly and masked - rendering the information they contain unusable. Volume level may vary from channel to channel in televisions. Some user need louder sound level and some may need lower sound level. The main objective of our project is to control the volume fluctuations of signals and adjust the volume of the TV/ radio according to that particular user profile based on the volume level. So, user doesn’t need to bother about the volume controller of the TV/ radio. The main components of our system are Mic module, Tsop1738 IR receiver, Arduino Nano Microcontroller, IR transmitter, Battery clip(9v battery) and switch. Software point of interest is Arduino IDE and embedded c language is used. With our Automatic Volume Control system(AVC), the volume of any sound system can be adjusted simply by using the record code and recording the signal so that no matter which channel the listener will change, they will hear the same volume level. System is very cost effective and high performance system.
