Why can we hear through walls?
Show answer & explanation
Answer: Sound vibrates solid matter
Sound vibrates solid matter ✓ — Correct! Sound waves make wall molecules vibrate, passing energy through the solid material. The wall then vibrates air on the other side. Low frequencies travel through walls better than high ones—that's why you hear bass from neighbors!
Air leaks carry sound — Wrong. While air gaps help sound travel, sound also moves directly through solid materials by vibration.
Walls amplify sound waves — Wrong. Walls actually reduce sound, they don't amplify it. Some sound still gets through through vibration.
