What is the difference between an omnidirectional and an isotropic antenna?

An omnidirectional antenna can be practically implemented but an isotropic antenna cannot be implemented practically. An isotropic antenna resembles an ideal antenna with ideal values for all parameters.


What electromagnetic wave does a microphone use?

None. It reports sound wave intensities. Some mics use a magnet to operate.


What do eardrums do when sound waves reach them?

The eardrums are like an omnidirectional microphone. The sound pressure vibrates the membrane (diaphragm) of the eardrum and the microphone only from one side.


Why do you need different types of microphones?

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.


Where did the 1000 Hz sound come from?

Humans hear sounds best in the 1,000 to 5,000 Hz range which is where speech is centered. That is why they chose the 1,000 Hz as the test tone. Being on the lower range it is more omnidirectional and can be heard easier than any other frequency. The term Hertz (Hz) comes from the German physicist Heinrich Rudolf Hertz.
