Consider the difference in sound between a large empty room that only has hard walls to reflect sound compared to a room with different kind of furniture and curtains or drapes. An echo occurs when sound (sound waves) reach a solid object that reflects the sound away and back to where it originated. If there is no echo than any or all of the following occurred:
- The sound waves were reflected in a different direction.
- The sound waves were absorbed when they reached a soft material that does not reflect sound well. The sound energy is converted to smaller vibration in the material which dissipate.
- The sound waves were attenuated (lessened) as they traveled through the air until it was inaudible (couldn't be heard). Some of the waves are absorbed by the ground, grass, trees or bounced away by obstructions and the rest are absorbed by air particles which gain a little energy from it.
Interestingly, the amount of air particles over water is less than over land and most people are aware that sound travels further over water.

How do yow see soundwaves?
Soundwaves are typically invisible to the human eye as they are a type of mechanical wave that travels through a medium such as air or water. We perceive soundwaves through our sense of hearing when they cause vibrations in our eardrums, which are then processed by our brain as sound. Specialized equipment like oscilloscopes or spectrograms can be used to visualize soundwaves as waveforms or frequency patterns.
The loudness of a sound is directly proportional to what attributes of its soundwaves?
The loudness of a sound is directly proportional to the amplitude or intensity of its soundwaves. This means that the greater the amplitude of the soundwave, the louder the sound will be perceived.
What is a sound wave that reflects off a hard surface?
An Echo-echo-echo-echo! The answer is Echo
What happens in meiosis you that does not occur in meiosis?
One thing that happens in meiosis that does not occur in meiosis is that produces 2 cellular divisions. This occurs as a direct result of sexual reproduction.
What tube permits soundwaves to reach the eardrum?
The auditory canal allows sound to get to the eardrum.
Did echo be heard on a ho tter day?
An echo can be heard during a hotter day. In fact, soundwaves travel faster during hotter days so a person would hear the echo a lot sooner than they would on a really cold day.
What is the name of the show on cartoon network where the main character can use a power called echo in which he has to shout for it to work and it comes out in blue soundwaves?
BEN 10
What happens to echo after narcissus runs away from her?
echo turns into the echo we hear today.
What happens when sound gets louder?
It means that the amplitude of the soundwaves is increased, or is increasing if the sound continues to get louder.
Why is there an echo in the gym of a school?
more than likely due to the solid walls, hardwood flooring and non sound absorbing materials used in the bleachers. The lack of articles and material that would absorb sound waves provides a surface to bounce the soundwaves around creating an echo.
Why is echo only occur in mountainous areas?
Because an echo needs a solid surface for the sound to 'bounce' off.
What collects soundwaves?
eardrum
Does the dark affect soundwaves?
No
What happens in an Echo in the Darkness by francine rivers?
it gets destroyed
What are the release dates for Soundwaves - 1983?
Soundwaves - 1983 was released on: USA: 30 March 1983 (San Francisco, California)
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 verb describes what happens to words that are shouted in the mountains?
They will 'echo' back to you...
