Woofers or bass speakers.
Assuming this happens in phase, the pitch of the sound will increase. If only one of the loudspeakers does this, they'll be out of phase, which will initially sound like a slow pulsed beat, but eventually will form a chord.
By microphones, amplifiers and loudspeakers.
yes, the pitch of sound does, in fact, depend on the frequency of the sound wave.
The sensation of a frequency is commonly referred to as the pitch of a sound. A high pitch sound corresponds to a high frequency sound wave and a low pitch sound corresponds to a low frequency sound wave.The ability of humans to perceive pitch is associated with the frequency of the sound wave that impinges upon the ear. Because sound waves traveling through air are longitudinal waves that produce high- and low-pressure disturbances of the particles of the air at a given frequency, the ear has an ability to detect such frequencies and associate them with the pitch of the sound.
Because of the gravity of the earth
They sound if you have amplifier and shut if you don't
large,thick things produce a low pitch sound
When the frequency of the vibrations that produce the sound change. Higher frequencies -> higher pitch. OR if the source of the sound is moving towards or away from you -> Doppler effect.
No, because the loudspeaker creates sound while the ear receives sound.
Trumpets produce sounds by buzzing your lips into a mouthpiece connected to the trumpet. the faster you buzz your lips, the higher pitch the sound, the slower, the lower. the pitch can also change by pushing down the valves in different combonations
it produces a low pitch sound
Because of the vibrations in the air.
