How Do You Build A Shotgun Microphone?
Shotgun microphones are the most highly directional types of microphones. This means that they have an extremely low sensitivity to sounds occurring behind or to the sides, but an extremely high sensitivity to sounds occurring in front. For this reason, shotgun microphones are excellent at detecting sounds far in the distance, and are frequently used to record wildlife and sporting events. Decide what frequencies of sound you want to hear. A simple shotgun microphone with only a few tubes will be able to pick up only a limited frequency range of sounds. If you want to produce a higher fidelity recording with your shotgun mic, you’ll need to use most or all of the 56 feet of tubing you’ve acquired. Do some calculations to determine the lengths of the aluminum tubes you’ll have to cut. Aluminum tubes resonate at particular frequencies to pick up sounds. Dividing the speed of sound (1,100 feet per second) by a given frequency will determine the wavelength. The length of a given aluminum t
