What are the 5 characteristics of sound?
Sound wave can be described by five characteristics: Wavelength, Amplitude, Time-Period, Frequency and Velocity or Speed.Wavelength.
Velocity of Wave (Speed of Wave).
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?
The Krakatoa volcanic eruption: Not only did it cause serious damage to the island, the eruption of Krakatoa in 1883 created the loudest sound ever reported at 180 dB. It was so loud it was heard 3,000 miles (5,000 km) away. 3. A 1-Ton TNT Bomb: An explosion from this bomb would measure 210 dB.

Which sound is loud?
0 decibel is the so-called hearing threshold for the human ear. While we can hear more than 140 decibels, it is too painful for our ears and if you expose yourself to such a loud noise you are at extremely high risk of permanent damage to your hearing. The table blow shows how loud sound is.
What are the 3 types of sound?
Sound can be of different types—soft, loud, pleasant, unpleasant, musical, audible (can be heard), inaudible (cannot be heard), etc. Some sounds may fall into more than one category. For instance, the sound produced when an aeroplane takes off is both loud and unpleasant.
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.
