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.
People might think that once nitrogen is used to inflate tires that they no longer need to check the inflation pressure. Hopefully these tire blogs and discussion with our faithful readers will be a good reminder that there's no substitute for regularly checking your car's tires.e filled one tire per model with air and the other with nitrogen. The test was quite simple: fill and set the inflation pressure at room temperature to 30 psi (pounds per square inch); set the tire outdoors for one year; and then recheck the inflation pressure at room temperature after a one year period.
