The sound wave generated during thundering, successive reflection of sound wave takes place between the clouds and the land which results in the echo sound causing thunder rolling. This is because bone conducts sound vibration that hits the hearing aid. They experience echo-like sound of their own voice at the beginning. The echo is common in new hearing air user. You can hear the echo from heavy artillery barrage in night because during night the place is vacant and calm. Artillery barragesĪrtillery barrages are good echo sound examples only in night. Thus the echoes are produced at the bottom of the open well. There are no such things inside the well which can absorb the sound waves. When the sound waves strikes the bottom of the well consists of water and rocks, they bounces the sound wave similar to the floor bouncing the ball. When you drop a stone in a well or you speak, you will hear the repeated sound which is nothing but echoes. These echoes are caught by the dolphins at their jaw lines consisting of cavities filled with fatty tissue that channels the sound wave and interprets the shape, size and distance of the obstacle. When these sound waves strike the obstacle, they return to the dolphins as echo sound. It is hard to identify the object underwater so the dolphins use the sound waves of high-frequency clicks which transmit faster under the water.
Dolphinsĭolphins are the marine mammals which has the unique quality of seeing the things via echo sound energy. The echo sound in cinema hall is very less because the roof of the cinema hall is covered with the sound absorbent materials such as draperies or compressed fireboard but a small amount of echo is generated before filling the cinema hall with audience and before the cinema begins. So that from the auditoriums can be excellent echo sound examples only when the sound is generated in the empty auditorium.
#Sound reflection examples full#
In auditoriumĮcho produces only in the empty auditorium not in the auditorium full of audience because the audiences are obstruction for the sound waves and they cannot reflect by the audience. Both mountains reflect your voice so you will hear multiple echo of your own voice between the two vertical mountains. If you are standing between two vertical mountains and you yell some words, it will echo because both mountains are hard and cannot absorb the sound wave from your mouth. The empty new building has large vacant area and there will be no objects which can absorb the sound, so you can hear the echo of very low voice in the new building. The empty new buildings are the perfect echo sound energy examples as they produces echo of low sound also. If you clap your hand in front of a wall, you will hear the echo of the clap which is same as the original sound of the clap.Ĭlapping near the wall as Echo sound examples Echo in new empty buildings Walls are generally hard and they cannot absorb the sound waves, so they reflect the sound energy. Thus the voice echoed when you shout on the top of the hill is one of the common echo sound examples. The echo produced on the top of the hill is because there will no object around the hill which can absorb the sound energy from you and the surface reflects your own voice. When you shout your name or anything loudly on the hill, you will hear your voice twice, one is your original voice and another one is echo. When you shout loudly from the top of the hill The above-listed echo sound examples with its explanation is given in this section. The echo sound produced is same as the original sound that heard by the listener within a fraction of second, say 0.1 second. The smooth obstacles do not produce the echo sound energy because they can absorb the sound waves. The repeating waves of sound energy that generated due to reflection of sound wave only by hitting the hard surfaces are known as echo.
Generally, the eco is produced when the sound travels in a large vacant place. The production of echo is due to the reflection of sound waves, which repeatedly arrives at the listeners.
