A microphone (or mic, for short) is commonly found everywhere these days and have several different types of uses. A microphone is pretty much a compulsory piece of electronic and audio equipment on the modern day person. All of our daily electronic devices and computers have a microphone, and the most common use for a microphone is the ones found in our smartphones and feature phones – the ones used to make calls.
There are many different types of microphones, mostly made for very general and multipurpose usage, while some are made for very specific uses, such as made to record only a certain type of music instrument. It is a good idea to learn more about the different microphones before deciding to purchase. Here are two types of commonly used microphones today:
Dynamic microphones are the most common type of microphone found and used almost everywhere. They are commonly used in during talks and assemblies, at concerts, and even at the karaoke lounge. Dynamic microphones are named as such because of their moving diaphragm design where an induction coil is attached toe the diaphragm in the field of a permanent magnet, which moves when sound enters the windscreen. These are reliable and can be used in a wide variety of situations as they are also able to capture loud sounds without distortion. Some dynamic microphones are also tuned for certain frequencies only, such as bass (lower frequency.
Condenser microphones use a thin conductive diaphragm that when sound enters, it vibrates to change the capacitance to produce audio signal. Condenser microphones are usually used for precision recording in studio, such as vocals or music instruments, as they have very high fidelity and sound quality, but at the expense that they cannot record sounds at high levels (volume).They also require phantom power to work – and they're also not quite as sturdy, so handle with care!
Or in simpler terms, the direction and pattern of how a microphone will pick up sound. As a microphone has several different uses, the different patterns allow for more efficient use.
- Cardioid Microphones: Captures all sound in front of the microphone and blocks out the rest - this is an ideal pattern for directional audio capturing and reducing ambient sound. This makes it an ideal choice for live music performances or speeches where noise reduction is important.
- Omnidirectional Microphones: Like its name suggests, an omidirectional microphone captures sound from all angles without any dead-zones. This allows the microphone to capture very subtle nuances better, most prominently in locations with great acoustics such as big halls and churches.
- Figure-8 Microphones: The term "figure-8" is the description of the pattern that the microphone uses to capture sound. These types of microphones capture sound only at the front and the back while the sides are blocked off. This makes it ideal for stereo recording and the sound recording from two different instruments.
Knowing your needs for a microphone can help you understand which type of microphone you should acquire, so that you will be able to be more efficient with it.
