A cardioid microphone is a special kind of microphone that picks up sound in one direction and transmits it the other direction. These microphones are often called cardioid with a “C” for cardio. A cardioid microphone has three capsules, usually two capsules with a -10dB noise reduction factor. There is also a mid/high pass capacitor, but this one doesn’t always have a -10 dB factor. A cardioid microphone is used to pick up sound and send it in one direction. It is sometimes used as a stereo mic, picking up just one direction or both directions.
Many musicians and sound engineers use cardioid microphones when they want a very directional response. For instance, if you are performing live at a club and someone kicks you in the groin, your sound will come from the diaphragm and not your ear. If you are sitting in a soundproof room and someone kicks you in the head, your ear and your nose will pick up the sound and transmit it to your ears, which is a much more powerful signal. When you are sitting in a club, you want the sound from all directions to be reflected back to you, and that is why these microphones are great.
A cardioid microphone has two capsules. The cardioid capsule acts as the receiving capsule, while the condenser microphone capsule acts as the one that sends the sound into the speaker. This can be a little problematic. The sound waves have to go from the condenser mic to the headphone, then the sound waves have to go back through the headphones. This isn’t something that happens all the time, but if you are using a headset, this could be a significant problem.
Another problem is that many musicians prefer their sound to be much louder than what the diaphragm can handle. In fact, many studio headphones can’t handle the volume of some musicians’ music. This is why there are cardioid microphones. These microphones use an additional diaphragm that is separated from the audio portion of the diaphragm, and this creates a cancelling effect that cuts down on the overall volume of the sound. These microphones are ideal for any type of high volume pop or rock sound.
These microphones are usually equipped with a lot of circuitry that takes care of the cancellation issues, and some brands even include extra features like touch-screens or other external controls. There are a number of headphones that include the cardioid built in, so make sure to ask the person at the store if they are aware of this. Some models of this type of microphone will even come with extra diaphragms that can be moved to wherever you need them.
Now that you know what a cardioid microphone is, you should be able to understand a bit more about what makes them so useful. They are ideal for using outside during concerts, as they can pick up sounds better than dynamic microphones can, without losing the quality of the sound that you get. This also works well for noise cancelling headphones, because they can pick up external noise as well. In general cardioid microphones are perfect for both wireless and wired applications.
