Question: how does the noise happen when you clap?

Keywords: , ,

  1. When you move your hands together, its creates ripples (oscillations) in the air which disturb the air at various frequencies, causing sound. If you had sensitive equipment, you can hear the sound your hands make as they are moving through the air to, they just happen at a much lower frequency that what our ears can hear.

  2. Noise, or sound, is picked up by your ear from vibrations in the air. As Brad has already mentioned, you probably wouldn’t hear all of the frequencies (high or low) that was caused from clapping. Some animals can hear a wider range of sound frequencies than humans.

    Clapping is no different than playing a piano or violin: When you hit a piano key, a hammer strikes the string and causes that to vibrate. This vibration then moves the molecules in the air and that carries all around, eventually hitting your ears to be converted as signal of sound. A violin causes noise when you draw your bow across the string to cause vibrations.

    If you want to see vibrations, get a glass of water and place it on a speaker facing upwards. You can see the vibrations travelling through the water instead of air.

  3. Sound is really just vibrations in the air, as the others have mentioned, and it only “sounds” the way it does because of the way that your ear detects the vibration and tells your brain it has done so, and the way in which your brain interprets that information.
