Sound Transmission

What is sound transmission?

• The process of sound waves being absorbed by a medium.

• The process of sound waves traveling through a medium.

• The process of converting sound waves into electrical signals.

• The process of sound waves being reflected off a medium.

What are the methods of sound transmission? In ​ (a)   , sound travels by the ​ (b)   of air molecules in the direction of travel. However, in (c)   , molecules can ​ (d)   in other directions, hence, a number of different types of sound waves are possible. There are two basic types of wave, ​ (e)   differentiated by the way in which the wave is propagated.

• compression and rarefaction
• air
• solids
• support vibrations
• transverse and longitudinal,
• liquids

What is the difference between sound transmission and sound absorption?

• Sound transmission and sound absorption are the same thing.

• Sound absorption products prevent noise from reverberating around a room, while high sound transmission loss materials serve to effectively stop sound waves from traveling into adjacent spaces.

How does sound travel through solids?

• By creating a vacuum within the solid.

• By passing through the empty spaces between particles.

• By generating electromagnetic waves within the solid.

• By vibrating the particles of the solid.
