WebRefraction, 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 will undergo refraction. Refraction of sound waves is most evident in situations in which the sound ... Web(See Sensing Sound Amplitude for more information.) Direction and distance. You can detect the direction a sound is coming from and, in some cases, its distance.

WebJan 10, 2024 · Sound waves wiggle all the bones in the chain until the last bone, the stapes, pushes on the oval window — a membrane separating the air-filled middle ear from the inner ear. When the vibrations reach the inner ear, they ripple the fluid inside a snail-shell-shaped structure called the cochlea. Now the sound waves are waves in liquid. If the direction of the sound waves is not from the sides, but rather from above, below or immediately in front of the face, there is no time lag between the ears. In situations such as this, the outer ear is important as it … See more Time lag is of particular importance when determining so-called impulse sounds like a click or a bang.
