What are examples of loud sounds?

Banging of a hammer and a car’s horn are examples of loud sounds while playing of a piano and sound of blowing wind are examples of soft sounds.

What makes sound loud or soft?

Amplitude and Distance It depends on the amount of energy that started the waves. Greater amplitude waves have more energy and greater intensity, so they sound louder. … The same amount of energy is spread over a greater area, so the intensity and loudness of the sound is less.

What makes a high sound?

Sounds are determined by how an object vibrates. … Sound travels more slowly than light. Sound waves travel at the same speed, but vibrate in different ways. Some vibrate quickly and have a high frequency or pitch, while others vibrate slowly and give a lower pitch.

What is the loudest possible sound?

Why do sounds get softer?

As distance from the sound source increases, the area covered by the sound waves increases. The same amount of energy is spread over a greater area, so the intensity and loudness of the sound is less. This explains why even loud sounds fade away as you move farther from the source.
