Hearing from far

1. Felix wonders: A teacher calls out from the back of the classroom. Why does the student at the front hear it clearly but the one in the corner hears it softly?

   • Sounds get weaker with distance (right)
   • The far student has a bad ear
   • The sound is blocked by walls

2. Mei wonders: A teacher says 'Hello!' from the back of the classroom. A student at the front hears it.

   • Louder (right)
   • Fainter
   • The same

3. When Priya listens to music from the playground far away, how does it compare to when it's near?

   • It is quieter (right)
   • It stops suddenly
   • It is louder

Tip: When a sound comes from far away, it has less energy and becomes quieter because it spreads out over distance.
