People who enjoy music wish to have the best acoustics in their cars since the travel time is the time when they wish to indulge in the world of melody. Acoustics is the quality that determines the ability of an enclosure to reflect sound waves effectively and produce clear distant hearing. This involves the role of several factors like road noise, vibrations, electrical interference, echoes, dead space and many more that make the car a good listening environment.
To improve the vehicle’s acoustics, the two key factors that need to be considered include elimination of environmental noise and enhancement of mechanical issues within the car for better audio effect. Road is a noisy place and other factors like wind, tires, and other vehicles on the road create a lot of background noise. To reduce the sonic clutter entering the car, damping materials like Dynamat can be installed around the vehicle cabin that act as shock absorbers for sound waves.
Elimination of noise yields better stereo effect and can be achieved by buying new tires, tuning-up the engine, replacing the muffler and tightening loose bolts and hinges to lessen rattles. Also, positioning the speakers equidistant and unobstructed from the listener produces better sound quality. Achieving time alignment (the simultaneous arrival of sounds to the ear from different locations) is also an essential factor while designing a car audio system for more realistic sound.
Mounting speakers in the upper portion of doors and/or placing them in the kick panel areas at a proper angle provide better results. Rear speakers are essential for better flight sound reproduction and work effectively when aimed at the listener rather than the rear glass. The use of unshielded twisted pair (UTP) cable keeps the electrical wires and speaker wires apart and thus avoids interference. A little effort can make your car audio system sound phenomenal.
