A sound wave has a fixed amount of energy. Because sound waves usually move outward in a circular pattern of increasing size, that energy gets stretched out over a larger and larger area, and the energy eventually becomes so thin as to be undetectable, or too quiet to be heard.

Sound waves in a certain time is called?
Number of waves in a time is "Frequency" Normally "Waves per Second" which is called "Hertz" - Hz
Why doesn't a subsonic aircraft produce a sonic boom?
A subsonic aircraft doesn't produce a sonic boom because it is subsonic, and cannot produce enough speed to do so. A sonic boom is created when an aircraft becomes supersonic, accelerating past the speed of sound. Since it is traveling near the speed of sound at this time, the sound waves build up around it, finally traveling through the air as it is left behind by the aircraft.
Frequency is the of sound waves produced in a given?
Frequency is the number of waves that pass a fixed place in a given amount of time.
What is the speed of sound waves when travelling through a vacuum?
The speed of sound in vacuum is zero. Sound needs a material medium in order topropagate. Since vacuum contains no material medium, sound does not propagate.Therefore, it never moves from the source of the sound, and theSpeed = (distance covered in any time interval) divided by (time to cover the distance)is zero.
What happens when two or more notes are played at the same time?
the sound waves interfere and create beats
Say true or false. all waves are traveling disturbances that carry energy from place to place?
It is true. A wave is a disturbance through space or time that carrys energy. For example, lets say sound waves. A sound wave carrys the energy (sound) to you.
How are beats produced?
When two or more sound waves are traveling at different frequencies and amplitude, there will be a time when these waves overlaps (superimpose) or cancel out each other. This will form a highest amplitude point and also a point where there is no displacement. This is called a beat.
Can sound waves originate in a small space and spread out to cover a bigger space?
As of being waves, sound waves does just that. They start from origin and spread out. Sound waves will however quickly fade with distance and time.
Why does the sound stop after a short time?
sound waves dissapate depending on location
Sound waves in a certain time is called?
Number of waves in a time is "Frequency" Normally "Waves per Second" which is called "Hertz" - Hz
What is the main characteristic of sound?
Sound waves travel at great distances in a very short time. But as the distance increases the waves tend to spread out.
How long will it take sound waves to reach you if the source is 40 kilometers away?
The speed of sound waves in air is approximately 343 meters per second. To calculate the time it takes for the sound waves to reach you, divide the distance by the speed. In this case, it would take approximately 116.8 seconds or about 1 minute and 57 seconds for the sound waves to reach you.
How long does it take Santa to deliver gifts to 880000000 children traveling at the speed of sound?
no idea, but due to time zones, he has longer than just a night ... or he has a time turner ... or a tardis ... =]

How does an echo sounder work?
An echo sounder works by sending out sound waves into the water and measuring the time it takes for the sound waves to bounce off an object or the sea floor and return to the device. By calculating the time taken for the sound waves to return, the device can determine the depth of the water or the distance to the objects in the water.
If a car is traveling at the same speed for a long time it is said to be traveling at what?
cruising speed
Does it sound natural It was a long time you were waiting for it?
It does not sound natural that you were waiting for a long time for it
