Fundamentally, a door is a moveable continuation of a wall. So it should have the same properties as the wall - sound, thermal, maybe opacity but maybe not, and so on.
A sound barrier is the construction product that minimizes the sound from travelling from one place to another. So it should be as massive as practical, and most important, there should be only tiny gaps round the edges.
A small crack round the edge of a door will allow the sound to get past the door. Equivalent to a one-quarter wavelength each side of the crack, multiplied by the length of the crack! So ensuring those cracks are sealed as much as possible is a good start. Most doors naturally have a labyrinth path at the edges, and that does aid.
Doors can stop sound from traveling through because they are dense and rigid, which helps to reflect and absorb sound waves. The materials and construction of the door can block sound vibrations, preventing them from passing through. Sound waves are also disrupted by the seal around the door, which reduces sound leakage.
A sound wave traveling through the air eventually dissipates as it loses energy due to interactions with molecules in the air. This causes the sound to become quieter over distance.
Sound can travel through any state of matter, including solids, liquids, and gases. The speed of sound can vary depending on the medium it is traveling through, with sound traveling fastest through solids and slowest through gases.
Heat can affect the speed of sound by changing the density of the medium through which the sound is traveling. Generally, in warmer temperatures, the speed of sound increases as the molecules in the medium have more energy and can vibrate faster. This can result in sound waves traveling faster in warmer air than in colder air.
A drop in pitch is observed when the frequency of the sound wave decreases. This can happen when an object producing sound moves away from the listener (Doppler effect), or when there are changes in the medium through which the sound is traveling, such as in the case of a sound wave traveling from air to water.
In a sound wave, air particles vibrate back and forth in the same direction that the sound wave is traveling. This vibration creates a series of compressions and rarefactions in the air, allowing the sound wave to propagate through the medium in a longitudinal wave motion.
no sound never stops traveling!

When something is traveling at the speed of sound, 343 m/s, it is said to be traveling at mach 1. When traveling at twice the speed of sound it is traveling at mach 2 and so on. Wikipedia.org, 'The World's Encyclopedia' has an entire article on Mack Number. Refer to the related link in the Related Links section below.

The speed of sound is only 768mph.
When traveling at 35 mph it will take you 210 feet to come to a complete stop
