From the cheerful chirping of birds in the morning to the hustle and bustle of traffic in the evening, some sounds are pleasant and some, well, irritating. In other words, sound is all around us. But how can we explain what is sound and its properties to students without boring them with scientific jargon? Here are some interesting facts about sound waves in science that can help you out.
Amazing Fun Facts About Sound Waves
1. Sound is a type of wave caused by the vibration of objects.
2. Sounds produce a low level of energy.
3. It needs a solid, liquid, or gaseous medium to travel from one place to another.
4. Sound moves faster through water than other mediums.
5. Sound travels slower than light which is why we hear things after we see them.
6. Sound is measured in decibels and pascals.
7. The measurement of sound is related to its pressure and intensity.
8. Sound does not travel in a vacuum.
9. Excessive loud or unpleasant sounds are called noise.
10. Humans can hear sound waves with frequencies between 20 Hz to 2000 Hz. They are also known as
11. Sound waves with a frequency below 20 Hz are called infrasonic waves.
12. Humans cannot hear infrasonic sound waves.
13. Waves with frequencies above 2000 Hz are called ultrasonic waves. Although humans cannot hear them, some animals, like dogs, cats, and bats, can hear them easily.
14. Some cows, when exposed to calm sounds, tend to become relaxed and produce more milk.
15. Researchers suggest that sound waves can be used to put out fires.
