An echo is a distinct repetition of the original sound. The reflection of sound from a cliff face for example. A flutter echo is s separate class of echoes (according to the acousticians), and will be experienced in a relatively bare room, where an impulse sound such as a clap will be heard multiple times, but quickly decreasing in volume. Your bathroom might be a good place to try for one.
In a concert hall (or a lecture room), an early reflection of the sound will not be perceived as a separate signal, but will aid in better understanding of the source, and may in fact be the source of the majority of the signal at that point. The source of the sound will still be seen as that from which the signal was first heard. Our ears have some truly remarkable properties.
Reverberation is the sustained repetition of echoes of the original sound. A small amount of reverberation is a desired feature in a concert hall, as it adds warmth to the sound. But excessive reverberation; as in many cathedrals for example; seriously interferes with the understanding of speech. It suits organ music very well.

Wave that moves back and forth?
True. The up-down type of wave is called a "transverse wave". Light, for example, is this kind of wave. Sound, however, is a different kind of wave. It is the back-forth type, called "longitudinal", or "compression" waves.
Is high pitch close together spacing in sound waves?
No The pitch you hear is determined by the frequency of the sound wave (how fast the particles oscillate back and forth). Higher frequency => higher pitch.
What type of waves are caused by a back and forth movement or vibration of an object?
earthquakes
Why does cupping your hand around your ear make a sound louder?
catches more sound. your ears are already on an angle, so cupping your hand enhances that angles/amount of sound captured
Why do voices echo?
Voices echo because the sound waves create by the human voice bounce off an object and reflect back to the original source. Echos will usually take place in wide open spaces because the objects are far apart, thereby the sound takes longer to bounce off an object. When in closed spaces that absorb sound like a voice over booth, you will not hear any echo as objects are closer and the sound is being absorbed by soundproofing.
Do sound sound waves travel up or down and back or forth?
Back and forth in the direction of propagation of the sound waves.
When the sound waves hit the ocean floor they bounce back or?
yes they bounce back now can i ask a question
How do curtains and carpets help in acoustical control?
A simple answer from a simple man. Sound waves travel until they hit something solid and then bounce back. Carpet and curtains are not even solid surfaces where sound waves can bounce back from. If they (the sound waves), have nothing to bounce from they stop traveling. The material of the carpet and curtain actually redirects the sound waves throughout the material instead of coming back to you.
How does an echo work?
An echo happens when sound waves bounce off an object. That's why if you scream into a hollow cave, there is an echo. Because the sound waves bounce off the walls and back at you
What are echoes and how are they formed?
Sound that bounces back is called an echo and they are formed when sound waves are called a bellend.1. Sound travels in waves2. These waves bounce of nearly everything3. Sometimes these waves get absorbed or run out of energy4. If you are in a big room/place with nothing in these sound waves bounce around and end up coming back to your ears!
Why Waves refracts?
not all of the waves are reflected.This is how it goes,if sound waves hit a smooth,hard surface.Some of the sounds are reflected.the sound that bounce back is called an echo
Sound waves are created by particles moving back and forth or?
yes

How do dolphins use echo?
they will send out the sound and once it hits the fish, the sound waves bounce back to the dolphin forming a picture for them.
How an echo is formed?
An echo is formed when sound waves hit a solid surface and bounce back in the direction they came from.
What is a quick back and forth motion called?
Vibrations
How does a bat use ultra sound?
Bats use ultra sound by sending out ultra sound waves and then when the bounce back the know exactly where everything is even in the dark. I will work better with ultra sound because all of the wave will bounce back otherwise some of the wave will be absorbed.
