What is a cardioid microphone?
Over the years, several different microphones have been designed to perform very different tasks. Some - for example, the capacitor microphones - pick up a large amount of sound from several directions, while others pick up one concentrated sound from only one direction. From this second group, the cardioid microphone is perhaps the most popular because it almost exclusively selects the desired sound, while the surrounding noise is hard to see. He gets his name because of his pattern of sensitivity, which is roughly shaped as a heart when he is drawn on the axis. This means that most of the sound it picks up comes from the front of the microphone, while from the back the minimum noise raises and only marginal noise is raised from the sides. It can be a condenser microphone that uses a condenser system to pick up a sound or a dynamic microphone that uses a coil connected to the diaphragm. When the membrane vibrates, it moves through a coil, which then creates electromagnetic induction.
as a one -way microphone - ie one that raises the sound from only one direction - this microphone is designed to pick up one sound well and other ambient sounds disappear into the background. If this microphone is still not enough to remove the surrounding noise for the user's purposes, the supercardiide microphone eliminates even more noise from the microphone. The supercardiide microphone is often confused with a hypercardiide microphone that does not actually exclude so much noise behind the microphone, but eliminates more on the sides. Of the three types, hypercarddoid is considered the most common.
For musical purposes, cardiooid microphone is particularly useful for live sounds such as concerts. It can also be used as a vocal microphone for presentations, public address and other situations that require a voice microphone. Style is also a good choice for recording concentrated sounds such as vocals and certain types of drums.
Other situations in which cardioid microphone can be used, involvingHousehold applications, for example on your phone. The microphone in the handset lifts the speaker's voice and at the same time eliminates other ambient noise, such as a background conversation or television.
