Shotgun Microphone

Shotgun mics are one of the types of directional mics. The design of these microphones is such that they receive less surrounding sound than in the front. This made these microphones capable of receiving quality sound from the sound sources in front of them.

The reason for the name of these microphones is because these microphones look very similar to gun barrels. A strange and clever design has been made in the shotgun microphones. These microphones have a cylindrical tube with slots and grooves on the body of this cylinder.

A microphone capsule is placed at the end of this cylindrical tube. This caused sound waves entering the microphone receiver capsule from the front to be received by the capsule, but sound waves that are sent from around the microphone to the microphone enter the cylindrical tube through the grooves on the microphone body.

This causes the surrounding sound entering the microphone to have a phase difference to the sound that can be received in front of the microphone. As a result, the lateral sound is removed due to the phase difference with the sound waves received from the front.

Due to the function and type of sound wave reception by this microphone, these products are also called "interference tube".

Generally, in terms of design, shotgun microphones are classified into long and short categories. These microphones are one of the most important types of microphones in the sound stage and film industry and it can be said that there are hardly any films that have not been used to record the sound of these microphones.

They usually use long shotgun microphones to make movies. These microphones are used separately and are connected to the recorder independently from each camera.

At the same time, other types of shotgun microphones can be installed on video cameras and cameras. These microphones are designed to receive sound waves at a closer range.

Shotgun microphones, like other types of microphones, need a power source to receive sound from audio sources. In some models, this amount of energy may be provided by another device, or some of these microphones need a battery to receive sound waves.
