Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

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

1. What is the core principles?Mass, decoupling, absorption, damping, and sealing are fundamental to sound isolation
2. What is the transmission paths?Sound transmits via airborne vibrations and structure-borne (impact) vibrations
3. How do heavy walls help keep noise out?Heavier walls, like concrete or many layers of drywall, are hard for sound waves to shake, so they block the noise from moving through.
4. Why do builders use something called "decoupling" in soundproofing?Decoupling puts a break in the structure, like a gap or a special channel, so vibrations from sound can’t travel straight through the wall or floor.

Reverberation: The persistence of sound in a space after the original sound source has stopped, due to multiple reflections.
Sound Transmission Class (STC): A standardized rating system measuring the sound isolation performance of building elements against airborne sound.
Impact Insulation Class (IIC): A rating system measuring the performance of floor/ceiling assemblies in reducing impact sound transmission.
