When a sound wave meets a boundary it may be: reflected There is a reflection when waves bounce off a surface. absorbed Energy is 'taken-in' by the material and the internal energy of the...

When a wave reaches the boundary between one medium another medium, a portion of the wave undergoes reflection and a portion of the wave undergoes transmission across the boundary. As discussed in the previous part of Lesson 3, the amount of reflection is dependent upon the dissimilarity of the two media. For this reason, acoustically minded builde...
Diffraction involves a change in direction of waves as they pass through an opening or around a barrier in their path. The diffraction of water waveswas discussed in Unit 10 of The Physics Classroom Tutorial. In that unit, we saw that water waves have the ability to travel around corners, around obstacles and through openings. The amount of diffrac...
Refraction of waves involves a change in the direction of waves as they pass from one medium to another. Refraction, or bending of the path of the waves, is accompanied by a change in speed and wavelength of the waves. So if the media (or its properties) are changed, the speed of the wave is changed. Thus, waves passing from one medium to another w...

Soft surfaces absorb a lot of sound because sound waves transfer energy by making the particles in them vibrate. Noise (unwanted sound) can be reduced by using soft materials to absorb it or hard materials to reflect it.
A sound wave is a longitudinal wave. When an object vibrates it produces a longitudinal wave which travels through air to your ear. For a sound to be heard you need three things:
