If you shout into the Grand Canyon,
your voice travels at the speed of sound (340 m/s) to the bottom of the canyon and back
, and you hear an echo.
What will happen if we shout into the canyon?
If you shout into a well or a canyon,
the echo comes back a moment later
. The echo occurs because some of the sound waves in your shout reflect off of a surface (either the water at the bottom of the well or the canyon wall on the far side) and travel back to your ears.
Can you hear an echo in a canyon?
When you yell into some canyons, after some delay, you can
hear your voice echoed back to you at a lesser volume
. This is caused by the energy of the soundwaves bouncing off of the canyon walls and returning to your ear, instead of the energy being dispersed or continuing away from you.
How deep is the Grand Canyon at a spot where you can hear your echo 5.2 seconds after you shout?
Answer: The depth is
884 m
.
What is an echo in sound?
An echo is
a single reflection of a soundwave off a distance surface
. Reverberation is the reflection of sound waves created by the superposition of such echoes. An echo can only be heard by humans when the distance between the source of the sound and the reflecting body is more than 50 feet in distance.
How far away is the canyon wall if it takes 4.9 s to hear the echo after you yell?
The canyon wall is
242 meters away
.
When you yell in a canyon you hear an echo of your voice Why is this?
When you yell into some canyons, after some delay, you can hear your voice echoed back to you at a lesser volume. This is caused by
the energy of the soundwaves bouncing off of the canyon walls and returning to your ear
, instead of the energy being dispersed or continuing away from you.
How far away was the canyon wall that produced the echo?
Since the sound’s movement is a round trip, the canyon wall is 3300/2 =
1650 feet away
. In 3 seconds, the sound will have traveled 3300 feet.
What is an echo what can you do to stop the formation of an echo?
- Cover the Floor. Carpets and rugs do more than provide soft padding for your feet. …
- Cover the Walls and Windows. Wall and window coverings reduce the amount of sound reflecting off window glass and hard wall surfaces. …
- Fill Rooms with Furnishings. …
- Install Acoustic Panels.
How far can an echo travel?
The velocity of sound in dry air is approximately 343 m/s at a temperature of 25 °C. Therefore, the reflecting object must be
more than 17.2m from
the sound source for echo to be perceived by a person located at the source. When a sound produces an echo in two seconds, the reflecting object is 343m away.
What causes a echo?
In general, an echo is caused by one of two things: 1.
Someone’s mic is too close to their speaker or sound output
. This could be two participants that are physically in the same room, or someone with an external mic that’s positioned too close to their speakers.
How long does it take to hear an echo?
If the wall is relatively flat, perpendicular to the source of the sound, and far enough away (but not too far), then you can hear the reflected waveform or echo. If the sound comes back in
about 0.1 second or longer
, you can readily distinguish the echo.
How do you calculate echo time?
For example, if the speed of sound in water is 1500 meters per second and the fisherman’s sonar device detects an echo in 0.02 seconds, the distance of the object under water will be d =
v*t
= 1500 meters per second * 0.02 seconds = 30 meters (back and forth).
What is an echo write a condition for an echo to be heard?
The necessary conditions for hearing an echo can be,
The distance between the sound source and the place where it is reflected from must not be less than 17m
and the period between hearing the original sound and its echo should not be less than 0.1 of a second.
What is an echo what factors are important to get a distinct echo?
The repetition of sound caused by its reflection of a hard surface is known as echo. Factors important to get a distinct echo are:
The minimum distance between the source and reflector of sound should be 17m. The size of reflector must be large enough as compared to the wavelength of the sound wave
.
