If you’re having trouble choosing omnidirectional and unidirectional microphones for your project, rest assured, you’re not alone. How do you choose a microphone for a specific purpose? So far, many people know the answer to this question only because they don’t know how the microphone works.
Some people have omnidirectional microphones because they think these microphones can meet most needs and are therefore the standard microphones for most types of projects. However, this article will clarify the differences and possible confusion between omnidirectional and unidirectional microphones in order to understand how they work and in what situations they are best suited for use.
Omnidirectional microphones are most commonly used in situations where you want to capture all of the surrounding or surrounding surround sound. As the name suggests, omnidirectional microphones receive signals from all directions. Therefore, the use of omnidirectional microphones is very different from omnidirectional microphones, which pick up sound from more specific directions and filter out unwanted surround sound noise.
The polar pattern of the omnidirectional microphone is spherical, allowing the device to pick up sound evenly from a 360 degree circle. In the case of forests, etc., this function is ideal when you want to pick up the ambient sound of birdsong, rustle of trees and whistling wind. An omnidirectional microphone is also usually used at concerts, where it is very important to capture the voice of singers and orchestral instruments through a microphone.
Now let’s take a closer look at the one-way microphone:
Again, as the name implies, a one-way microphone is used to receive or transmit sound mainly from one direction. However, the one-way function of the microphone is why some people criticize the use of this type without fully understanding its true meaning. The unidirectional microphone is designed to eliminate noise. By estimates of the work, the sound received by this type of microphone from the side is less than half the sound received from the front, and the sound received from the rear is less than one tenth of the received sound. It can effectively eliminate unwanted noises and provide better desired sounds.
This is why this type of microphone is a better choice for conducting interviews, hosting live performances or presentations in front of cameras.
The design, almost standard, makes the speaker more focused, making the message clearer.
Even in a room full of people with background noise, this microphone can make you hear the speakers more clearly. It’s technically impossible for an omnidirectional microphone to achieve this kind of clarity just because of the pickup’s polar design.
If you need to hide the one-way microphone without worrying about the muffled sound from the body or clothing behind the microphone, the one-way microphone is also better. This directional sensitivity, called unidirectional polar mode, is a very useful design feature of unidirectional microphones, which contrasts sharply with the polar mode of omnidirectional microphones.
The in-depth understanding between the two types of microphones can identify and highlight the differences in each type of operation. This is due to the built-in polarity pattern design, so it is best suited for any operation, so it should be easier to determine whether to use for recording or the best type of microphone for recording.
