Microphones are devices that are used to record sounds

Microphones are devices that are used to record sounds from an area into electronic media then transmit the audio waves back through the air as a signal to the speakers. A microphone,literally referred to as microphone,is a unit – a diaphragm – that converts vibrations in air into an electric signal.

Microphones are available in two different types: condenser microphones and dynamic microphones. Condenser microphones are used for transmitting sound from one location to another and for recording in recording studios or for use on portable devices like MP3 players.

Dynamic microphones

Dynamic microphones are generally made by pushing two plates against a diaphragm. These microphones are more suited to recording and broadcasting.

Microphones are available in several categories: cardioid microphones,omni-directional microphones,capsule microphones and omnidirectional microphones. A cardioid microphone has a cardioid shape,in which the microphone will produce a sound that is reflected by the microphone back to the source. An omni-directional microphone will have a cardioid shape and will be able to produce sounds coming in from either side of the microphone.

Omni directional microphones

Omni directional microphones have capsules placed between the diaphragm. The capsule will produce two different types of sound waves: one coming from the diaphragm and another coming from the capsule. Capsule microphones are very common in home studios. They can be used in conjunction with headphones to reproduce louder sounds that are often reproduced in studio.

Microphones are classified into three categories: cardioid mikes,omni directional mikes and capsule mikes. A cardioid microphone produces the same sound waves as its reflections when the microphones are placed at right angles to each other. On the other hand,an omni directional microphone produces sound waves that are identical no matter which direction the microphones are placed. A capsule microphone produces the same sound waves regardless of whether the microphones are placed in the front or the back. It is more difficult to detect and hear when these microphones are placed behind the microphone.

More efficient in converting sound waves

These microphones can be categorized based on their power: cardioid mikes are more efficient in converting sound waves to electric signals while omnidirectional microphones do not require that the source of sound is moving in a certain direction. Capsule mikes are most commonly used for broadcasting and recording because they are more sensitive to small sounds compared to other types of microphones.

There are three types of noise reduction that the microphones varies based on the quality of sound it produces: cardioid noise reduction,cardioid noise cancellation and cardioid reflection. The microphone works by reducing unwanted noise. It is also possible to adjust the sound of a microphone depending on the source of noise. It is possible to find a microphone which can produce low noise but also high frequency sounds.

Some microphones are suitable for one task only. For example,condenser microphones are useful for producing microphones which are able to produce crisp sound when capturing certain sounds. Some microphones are suitable for creating a clear sound for broadcast use. Microphones vary in price depending on the features that it provides and the amount of noise reduction it offers.
