Someone in your house is watching TV. You put your ear to the wall to listen to the TV. Then you walk into the room to watch TV. When you listen to the voices while in the room, they sound different than listening to them through the wall.

Why do the voices sound different when you listen to them through the wall?



Sound waves change frequency over long distances


Sound waves do not pass through solid materials


Sound waves travel at different speeds when traveling through different materials


Your ear processes sound differently when it goes through a solid.

Respuesta :

Answer:

Sound waves travel at different speed when traveling through different materials.

Explanation:

Sound travels quickly through air. However it takes longer for sound to travel through other materials like water. Sound may travel faster through water than liquid metal. This is because the different materials of different densities have a different sound speed when sound is passed through it.
