Dolby Digital is the name for audio compression technologies developed by Dolby Laboratories. It was originally named Dolby Stereo Digital until 1994. Except for Dolby TrueHD, the audio compression is lossy. The first use of Dolby Digital was to provide digital sound in cinemas from 35mm film prints.It is now also used for other applications such as HDTV broadcast, DVDs, Blu-ray Discs and game consoles.t was originally named Dolby Stereo Digital until 1994.

One thing that is important for proper driving conditions is proper tire inflation and pressure. The ideal range of pressure in cars is between 193-234 in kPa (kilopascal) or 28 to 34 psi (pounds per square inch). However, in heavier cars, such as minivans, the pressure can be higher, upwards to 303 kPa (44 psi). If a tire is under inflated by 41.4 kPa (6 psi), a loss of handling will be noticed and tire life will decrease. Most notable, fuel economy is reduced by 5%. If over inflated by 41.4 kPa (6 psi), the car will ride harsher since the car is more susceptible to potholes and debris.
Having the correct tire pressure is extremely important for getting good gas mileage and the most life out of your tires. Your car has a specific tire pressure that will give the best gas mileage, handling and tire life for that car, and itâs written right on the door of the car.Thatâs the one you should follow when filling up.On newer cars, the recommended pressure is most commonly listed on a sticker inside the driverâs door.If thereâs no sticker on the door, you can usually find the specs in the ownerâs manual. Most passenger cars will recommend 32 to 35 psi in the tires when theyâre cold.or the most consistent tire-pressure reading, make sure the car has been sitting overnight, or at least has been parked for a few hours. Do not inflate your tires to the pressure listed on the tire itself. That number is the maximum pressure the tire can hold, not the recommended pressure for the vehicle.
