The 4 Best Unidirectional Microphones

Knowing how to choose the best microphone for you implies knowing exactly what you need it for. Microphones, as we all know, vary in many of their characteristics, and it is a personal obligation to maximize those advantages for your own benefit. A live vocalist’s microphone is not the same as the microphone used for PC activities. Bothe of them could be excellent microphones and can be unidirectional, each geared for different conditions. In this post we will detail the best unidirectional microphones, and for what we can use them.

Unidirectional microphones are those that pick up the sound from the front, obviating or minimizing the lateral sounds and the sounds that are behind the microphone. This feature has many application advantages, which we will see in the course of our article.

What Are Unidirectional Microphones?

Unidirectional microphones can receive sound from one specific direction, usually from the front, and mute or attenuate all other sounds from other directions. The side of the microphone from where it picks up the sound is usually called the voice side. They differ from omnidirectional microphones in that the lasts pick up sounds from all sides.

If we review the polar image of a unidirectional microphone, we can see that the maximum sound gain is on its front side. And as we move the source sideways, the gain decreases, even reaching near zero values at the back. This graph is very much like a heart, hence the name cardioid.

With these graphics we can identify how much gain a microphone shows, and where it is directed. These microphones are widely used when the sound source is directly in front of it, and we don’t need all the other sounds. A vocalist at a concert, a classroom conference, or a podcast recording are good examples of where you could use a one-way microphone so that the other sounds around you are not on the recording.

How a Unidirectional Microphone Works

As if by magic, unidirectional microphones can pick up what they’re going for, but reject sounds on the sides and back.

For example, speak into a one-way microphone from all sides while listening to their output. Your reproduced voice will be louder when you speak on the front of the microphone and softer when you speak on the rear.

Because they discriminate sounds on the sides and rear, one-way designs help reject unwanted sounds, such as room acoustics (reverberation), feedback, or leaks. For this reason, they are the most popular microphone option.

Why Buy Unidirectional Microphones?

Unidirectional microphones pick up the sound using different patterns of polar response. Important considerations when choosing a microphone’s polar response pattern include the following:

  • Unidirectional microphones are less sensitive to off-axis sound than omnidirectional ones therefore they capture less ambient sound.
  • These microphones are best used when cleaner, less reverberant sound is needed.
  • Unidirectional microphones can be used at a greater distance than omnidirectional types and still achieve a high level of direct sound.
  • It is important to appreciate that direct sound weakens as it moves away from the sound source at a rate controlled by the inverse square law.
  • It’s also important to note that unidirectional microphones are subject to increased bass response the closer they are to a sound source. This phenomenon is known as the proximity effect.
  • Unidirectional microphones are less prone to feedback than omnidirectional types. Feedback is the unwanted leakage of audio from the speakers into a microphone, causing a loud screech or howl.

Important Points I Should Know Before Buying Unidirectional Microphones of Any Brand Or Model

There are many different types of microphones commonly used. The differences are generally described in two ways: the technology they use (dynamics, capacitor, etc.) and their directionality (omnidirectional, unidirectional, etc.). In addition to that, microphones have a number of other characteristics that must be considered.

When choosing a microphone, the first thing you should know is what features do you need. After that, you can worry about things like size, brand, cost, etc.

Directionality

Decide which type of directional pattern best suits your needs. Remember that it is generally better to use a less directional microphone in a position close to the sound source, than to be further away using a hypercardioid.

Frequency response

Make sure that the frequency response of the microphone is adequate for its intended use. As a general rule, flat response patterns are best, but in many cases a custom response will be even better.

Impedance

The golden rule is: low impedance is better than high impedance.

Noise Management

Remember that the diaphragm works by converting the vibrations of the sound waves into an electrical signal. And it is clear that, unless the microphone has some kind of protection system, the diaphragm cannot distinguish the difference between a desirable sound wave vibration and any other type of vibration, such as a person touching the microphone. Any type of vibration will become part of the generated audio signal.

If your microphone is likely to be subject to some type of driving noise or vibration, you will need a microphone that will help prevent this noise from being picked up. That is why high-quality handheld microphones generally attempt to isolate the diaphragm from vibrations by foam padding, suspension, or some other method. Poor-quality microphones tend to transfer vibrations from the housing directly to the diaphragm, resulting in terrible noise.

Please note that lavalier microphones do not usually have protection against noise handling, simply because they are too small to incorporate any padding. Therefore, it is important to ensure that they do not move or hit with anything while recording.

Which Unidirectional Microphone Should I Buy?

If you can afford it, it makes sense to buy a range of microphones and use the right one for each job. And if your budget is more limited, think of all the different things you need to use the microphone for and try to find something that will do reasonable work for as many of them as possible.

For vocalists, the Shure SM7B is a good starting point.
If you want to create videos, a useful option is the Blue Snowball Ice.
For studio recording, specifically voice, the Neumann TLM 103 is the highest performing one.
In percussion and bass sound recording the Bosch RE320 is the best.

Conclusion

In the end, sound is quite subjective; you really want a microphone that provides the sound you like. A good idea is to set up a controlled test, so record the same sounds using different microphones, keeping all other factors constant.

Make sure you are comparing apples to apples. For example, don’t compare a handheld cardioid and a shotgun cardioid in the same position, if you want to compare these microphones, make sure each one is placed in its optimal position.

We hope we have helped you choose the best unidirectional microphone and remember that at the end of the day, your purchase should be geared to your needs, and of course to your pocket. The four microphones recommended here are of very good quality. Good luck and good purchase.
