because the minimum distance between the us (the source) and the reflector
should be 16.5 cm.
An echo of a wave is exactly the same type of wave as the original wave. An echo is simply the original wave returning to the observer, so if you made a sound (a longitudinal wave of vibrating air molecules), the echo is also sound waves.
Sound is a wave that travels through air and an echo usually occurs when you are surrounded by walls or in a tunnel of some sort. The sound wave that comes back to you has already hit the wall and bounced back so you can hear it again.

I've heard that you can. If you go to Menards, or Home Depot they have square pieces made of the same thing as egg cartons. I made a small booth and insulated it with that, it helps tons.
Yes. A sound wave was sent from a source which made a noise, it hit some solid object and was reflected back to the hearer, who hears the echo some time after hearing the original noise.
An echo is heard when sound waves bounce off a surface and return to the listener's ear with a slight delay. This delay is due to the time it takes for the sound waves to travel to the surface and back. The distance between the listener and the surface, as well as the acoustics of the surrounding environment, can affect the clarity and intensity of the echo.
The sound waves travel till a solid vertical obstacle, hit it and bounce back, travelling towards you. When they reach you, you can hear the sound you made, but it's several seconds off, the delay depending on the distance the sound had to cover.
Echos are created by the reflection of sound waves from a surface.
The Greek goddess of sound was Echo. She was cursed by Hera after distracting her with gossip. After Echo wasted away for love of Narcissus, she was made into an immortal.

Like a glockenspiel (both are made of wood) but each note has a sort of echo provided by the gourd underneath. It's a really pleasant sound!

A Sound that bounces back are called a few things. Here are the 3 most common * Echo * Reflect Sound * Mirror Wave Most People Call it an Echo The Word Echo, Comes from a greek myth, There was a lady named echo and she talked way to much, so the Gods cast a spell on her that made it so that the only time she could talk was when she hears something from someone else, the only thing that she can do, and she is forced to do it, is repeat the words exactly as she hears them.
* the repetition of a sound resulting from reflection of the sound waves; "she could hear echoes of her own footsteps" * (Greek mythology) a nymph who was spurned by Narcissus and pined away until only her voice remained * a reply that repeats what has just been said
Duck quacks do echo.It is a scientific myth that a duck's quack does not echo. Research has shown that a duck's quack does echo, but it is hard to hear because it is difficult to distinguish the quack from the echo.There are several reasons why it is difficult to hear the echo:Echoes are produced after loud noises. Ducks quack very softly, so the reflected sound is difficult to hear.A reflecting surface is needed to hear an echo. Ducks tend not to live near reflecting surfaces such as cliff faces or buildings. An echo could be heard more readily if the duck quacked whilst flying past such as surface.
