What is a hollow chamber filled with air that amplifies sound when its air vibrates?
A resonator.
What amplifies sound waves by as much as 20 times their original intensity?
A microphone and an amplifier with a loudspeaker does this. The microphone converts the soundpressure to electric signals. The amplifier amplifies these signals and the loudspeaker converts back the electric signals to sound pressure. Our ear drums are moved by the sound pressure as a sound field quantity. It is not the sound intensity as an energy quantity.
What let a sound or light wave through?
vaccum chamber
Can sound wave pass through in vacuum?
No - sound wave cannot pass through "vacuum". It was Robert Boyle, English scientist who proved in 1960 that sound waves need to pass through a medium to transmit sound. This can be tested as follows: Place a bell inside a chamber and slowly start evacuating air from the chamber. It can be seen that sound of the bell is slowly becoming softer, until there is absolutely no sound.
Why a bell ringing inside a vacuum chamber cannot be heard?
sound needs a medium to travel. material medium is necessary for propogation of sound. in vaccum sound do not travel. that's the reason why we are not able to hear sound in this case. Jordi101

What the function of tympanum?
The tympanum's function is to help the ear hear. It does this by vibrating sounds to the first bone in the middle ear called the malleus. It is commonly called an "eardrum."
What part of musical instrument amplifies sound waves?
resonator
How loudspeaker can increase the power of sound?
it amplifies the sound actually, by strengthening the waves. the sound waves are converted into equivalent electrical waves and then it amplifies and later those electrical waves are converted the sound waves . the principle of electromagnetic induction is applied here.
Resonance amplifies the sound of a guitar when the?
...frequency of sound is equal to the eigenfrequency (which depends on the shape of the guitar).

What is the basic difference between a cello and an electric cello?
The basic difference between a cello and an electric cello is shape and sound. An acoustic cello amplifies sound naturally inside the hollow body sound-box of the instrument. The electric cello has a slightly different shape, no resonant chamber at all, and a unique tone.
The harpsichord soundboard is a thick piece of wood that amplifies the sound of the strings?
False
How does a stethoscope magnify sound?
They are acoustic, inside is a diaphram that vibrates and amplifies sound passing it through the hollow tubes.
What part of a violin vibrates to make sound?
First the strings then the rest of it amplifies it.
