A vibrating object, such as a guitar string or vocal cords, moves back and forth rapidly to produce sound waves. The vibration creates changes in air pressure, which our ears detect as sound when they reach them.
No, ringing a bell is not an example of a pendulum. A pendulum is a weight suspended from a pivot that swings back and forth under the influence of gravity, while ringing a bell involves making the bell emit a sound by striking it with a clapper or another object.
The word 'emit' is a verb (emit, emits, emitting, emitted), meaning to give off, or send out.Example: The valve will emit steam when the water boils.The noun forms for the verb to emit are emitter and emission.
Bats emit high-frequency sound waves that bounce off objects. These sound waves then reflect back to the bat, allowing it to detect the size, shape, distance, and texture of objects in its environment and navigate effectively in the dark.
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."
Coal trains typically emit sound frequencies in the range of 500-2,000 Hz when moving. This range can vary depending on factors such as train speed, track conditions, and the type of coal being transported.

That is 'emit'
Sometimes they emit a sound ike 'Brrrawk', and sometimes they emit a sound like 'Screee...', so there are many possibilities available to the Falcon.
Emit
No, the northern lights do not emit a sound. The light phenomenon is a result of charged particles from the sun colliding with gases in Earth's atmosphere, producing beautiful colorful light displays but no sound.
