Answer:
Sound waves are travelling vibrations of particles in media such as air, water or metal. So it stands to reason that they cannot travel through empty space, where there are no atoms or molecules to vibrate.
Explanation:
For human ears, the audible range is 20 Hz to 20,000 Hz. The lower the frequency of vibration, the higher is the pitch. Unwanted or unpleasant sound is termed as music. Noise pollution may cause partial hearing impairment.
