Microphones are considered as very useful equipment. However, you should know that microphones have different types. Microphones differ in the technology and the directionality that they use. Because of these differences, you need to know what characteristics of microphone you need before you decide to purchase.
In choosing a microphone there are some things that you need to consider. These include:
Impedance – In microphones, a low impedance microphone is much better than a microphone with high impedance. However, it is quite apparent that high impedance microphones are relatively cheaper. The major disadvantage of high impedance microphones is that they do not perform well in long distance cables. Because of this, low impedance microphones are preferred.
Frequency Response – When choosing a microphone, you need to ensure that the microphone’s frequency response is appropriate for your needs. Frequency response actually refers to the way the microphone is responding to different frequencies. Some frequencies could be exaggerated while some are reduced. Condenser microphones have a flatter frequency compared to dynamic microphones. Thus, if you want an accurate sound, you might want to consider purchasing a condenser microphone.
Directionality – Since microphones vary in their directional patterns, you need to choose which one best fits your needs. Keep in mind that a less directional microphone is preferred if the microphone is to be used in a position that is close to the sound source. The directionality determines the microphone’s sensitivity to sound from different directions. There are some microphones that pick up sounds equally from all directions, while there are some that pick up sounds from one direction or from different combination of directions.
Handling Noise – Keep in mind that the diaphragm of the microphone works by translating vibrations from sound waves into electrical signals. The diaphragm of a microphone can’t distinguish the difference between a desirable sound wave vibration and other vibrations. Thus, any vibration will be a part of the produced audio signal.
To sum it up, the sound quality is subjective. If you want a microphone that will provide you a good sound quality, you can try recording the same sounds using different microphones and then select the microphone that produced the sound that you desire.
