According to the principles of physics, sound itself is unable to travel in a vacuum. Therefore, a microphone will be unable to amplify any sounds in a vacuum.
They are mainly used in various different kinds of Microphones. Sound sensor is also used in mobile phones.
The sound not travel through vacuum because sound need a medium to travel.
You need different types of microphones for different types of sound sources. For example, for a bass drum, you would need a microphone with the ability to catch low-frequency sound waves. For tom-toms or a snare drum, you need microphones that can pick up very loud (high SPL) sounds. For choirs, you need microphones with very large pick-up patterns. You need smaller microphones to be discreet. Vocal microphones onstage need to have excellent rear-rejection to help eliminate the risk of feedback from the mains or monitors.For live situations, omnidirectional microphones are not suitable because of the risk of feedback. Whereas with recording, different pick-up patterns can be more safely used.Most microphones (other than the Shure SM57 or similar mics) have a specific use that the mic is best suited for.
Sound proof glass is actually two panes of glass that have a vacuum between them. Since sound is a wave, it need a medium through which to travel. That's why astronauts can't talk to each other in space without the use of microphones. With no atter, sound can't be transmitted. So the vacuum between the panes of glass creates an area of nothingness where sound cannot be transmitted, and makes it soundproof.
hoe does sound travel im at school and i need to know!
Sound waves are carried throw the air. But sound waves can also travel throw liquids, such as water, and even through solids.
Sound is collected by microphones, which are devices that convert sound waves into electrical signals that can be processed, stored, and reproduced. Microphones can come in various types, such as dynamic, condenser, and ribbon microphones, each with its own characteristics suited for different applications.
By microphones, amplifiers and loudspeakers.
Omni-directional microphones are meant to pick up sound from any direction at any time. Unidirectional microphones pick up sound from only one direction.
no sound travels faster through solids.
Sound waves are carried throw the air. But sound waves can also travel throw liquids, such as water, and even through solids.
Microphones
According to the principles of physics, sound itself is unable to travel in a vacuum. Therefore, a microphone will be unable to amplify any sounds in a vacuum.
The sound pressure moves the human ear drums and also the diaphragms of the microphones. A sound wave is transformed by the microphone to an electric voltage wave, which is amplified by a microphone pre-amplifier.
