Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is acoustic transmission?Acoustic transmission is how sound waves move through a material like air, water, or metal. They travel by making tiny bumps and pulls that pass from one particle to the next. Sound needs a solid, liquid, or gas to travel; it can't go through empty space.
2. Why does sound travel faster in water or steel than in air?Sound moves faster in denser, stiffer materials. In water it goes about 1,484 meters per second, and in steel over 5,000 meters per second, compared to 343 meters per second in air at room temperature.

Acoustic Transmission: The physical process of sound wave propagation through a material medium.
Acoustic Impedance: The resistance a material offers to the passage of sound waves, calculated as density times the speed of sound.
Mechanical Waves: Waves that require a medium for propagation, transferring energy through particle displacement.
Reflection and Transmission: Phenomena occurring at the interface of two media, where sound energy is either bounced back or passes through.
