Topic: SOUND

Answer 1

Sound

Every day we take sound for granted, whether we're listening to music, hearing birdsong or covering our ears to protect them from the noise of a pneumatic drill, but how much do we really know the physics of sound? Sound energy is formed by vibrations that ripple the area around it causing longitudinal waves that form areas of high and low pressure. These travel to your ears and vibrate the eardrum, which your brain transforms in to the beautiful melodies or obnoxious noise we recognise as sound.
