When the speaker moves out, the air is compressed more than average and the pressure increases; when the speaker moves in, the pressure decreases slightly. The repetition of sound caused by the reflection of sound waves is called an echo. For example, if you have . Sound is defined as any vibrating disturbance in an elastic medium capable of producing an auditory sensation Sound waves are longitudinal waves traveling through a medium The particles of the medium vibrates and communicates the energy of vibration to the surrounding medium, usually the air, where the wave travels and is detected as sound This is because of the absence of a medium. A car's horn produces a sound wave of constant frequency. In physiology, sound is produced when an object's vibrations move through a medium until they enter the human eardrum. Longitudinal Waves.
