What range of frequency of sound do coal trains emit when moving?
The range of frequency of sound that coal trains emit when moving hovers around 20 Hz to 20,000 Hz
What does the word radiate mean in science?
To emit something, a sound, smell or aura.
Whenever a source of sound moves the frequency heard by the observer is Less than that of the source?
To be more specific, a sound source moving toward you will appear to emit a sound of higher frequency than actual. Conversely, a sound source moving away from you will appear to emit a sound of lower frequency than actual. See "the Doppler effect."
Things that create a low pitched sound?
Whales (but also the humble toadfish) emit low-pitched sounds that can carry extremely far under water. The speakers of professional sound systems used by bands and DJ's also have a lot of bass. Diesel engines when stationary emit a very low-frequency sound. On a bigger scale, earthquakes, avalanches and volcanic eruptions create a very low piched noise.
What are sound effects?
Sounds are vibrations carried through a solid, liquid, or gas. The Eardrum picks up these vibrations, which vibrate the Eardrum, and send the signal through the auditory nerve where the brain deciphers the signal.

Why is it called clapboard?
Because when you carry two or more pieces on your shoulder they emit a clapping sound.
Do ferrets use echolocation?
Not per se. Echo location requires the animal to emit high frequency sounds then tracking targets by the reflection of that sound. Dogs do not emit high frequency sounds, but do have acutely sensitive hearing, and are able to track by distinguishing the direction from which sound originates.
Is yelling a reflex?
Yes. All animals capable of vocalization emit a sound when in pain. It might be a defense or a warning.
How do you outward scream?
