A vibrating simple pendulum does not produce any sound because it oscillates at very low frequencies.
The lowest frequencies we can hear are about 20 Hz - 20 vibrations per second. If (for example) the pendulum moves back and forth once per second, it will produce sound at that frequency, which we are unable to hear. Also, the sound will be of a fairly low intensity.
if they are in a void no matter how much the object vibrates it won't produce any sound waves
Pitch is determined by vibration frequency. A guitar string vibrating at 440 times a second will product a perfectly tuned "A" note. A string vibrating any faster than this will produce a higher pitch, and any slower will produce a lower pitch.
Any vibrating set of particles, eg air.
When someone wants to perform vibrato, there actually isn't any vibrating going on! (well except for the string, but the string always vibrates when playing the violin) When vibrato is performed correctly, the person actually wiggles his finger which varies the pitch to create a vibrating sound.
Yes, provided there is a material medium between the vibrating object and your ear. Note that you'll perceive the sound only of the rate of vibration is between roughly 20 and 20,000 vibrations per second. If outside that frequency range, then the 'sound' is there, but your hearing system doesn't perceive it.
Your guitar string may not be making any sound because it could be broken, improperly tuned, or not vibrating properly due to issues with the frets or the bridge.
To produce any sound, you need a source of vibration, a medium for the sound waves to travel through (such as air, water, or solids), and a receiver (such as the human ear) to detect and interpret the vibrations as sound.
any sound you want
Yes, because it has a charge (+). Any charged particle that vibrates produces an electromagnetic wave at the frequency determined by the number of vibrations per second. The magnitude is determined by the how far the particle goes from max. to min. on each cycle.
An object or material that produces sound is referred to as a "sound source." This can include musical instruments, speakers, vibrating objects, or any other device that generates audible vibrations.
When you hit it, the triangle vibrates, and the air around it vibrates. The air particles closest to it vibrates, then the air particles next to the first ones start vibrating as well and so on, so it reaches your ear.
