CREATIVE THINKING - CAR AUDIO NORMALIZER

A detailed Summary of CREATIVE THINKING - CAR AUDIO NORMALIZER

My proposal for this project is a car audio normalizer. This device would be packaged as a microchip with various input and output pins. The reasons for this device have been experienced by almost everyone with a car audio system of any type.

Weather you own a simple factory made car radio or an expensive custom audio setup, an undesired affect occurs. A desired audio volume is set on the system at some point in time. The problem is that the environmental audio levels almost never stay constant. Typically, an open window, a passing vehicle such as a semi truck, or an increase in engine noise, drowns the audio out. When you manually adjust the audio level back to an audible one, the loud noise may often disappear. The truck passes, or you slow your vehicle, or close your window. After which, the volume level is undesirably high.

My proposed system would be activated when the radio was turned on. Each time the volume is adjusted, the system uses a microphone to sample the environmental audio level and calculate a ratio between the environmental audio level and the audio system volume. Then, using the microphone to sample the environment, the system maintains this ratio by adjusting

Modern systems, however, are digital, have digital volume controls, and take digital media. Therefore, a digital normalizer could be used as a component in these systems and would adjust the volume digitally.

There are several similar product patented and possible implemented and on the market. Patent number US5414386 is a muting apparatus for a car audio system. Patent number US5758272 is a patent on a gain controlling system, but it normalizes FM radio signals. There were several graphic equalizers patented, an example being patent number USD0310369. There is also a product on the market that raises the audio system volume in relation to the vehicle's engine rpm's. There are self tuning Dolby Digital 5.1 systems available. A environment audio level controlled system would be a great addition to an already potent arsenal of car audio equipment.

The technology that precedes this device is the heritage of car audio systems. Car audio rose to popularity in the 1950's when car radios we widely seen in new cars. The first systems that allowed users to play their own music in a car was an eight track system. This was followed by the popularity of the cassette deck in the 1980's. All these systems are analog, take analog media, and have analog controls, theref
