Various types of Microphones
This page explains the relationship between microphone types and their sensitivity.
There are many different types of microphones, so choosing one can be difficult. One way to choose is to decide which type to use depending on how far from your mouth you want to use the microphone.
Microphone sensitivity and advantages/disadvantages
Microphones have a specification called "sensitivity". A high value indicates high sensitivity, and a low value indicates low sensitivity. Each has advantages and disadvantages, as shown in the table below.
Microphone with high sensitivity
The higher this value, the more sensitive the microphone is, and the more distant the sound can be picked up. In other words, the advantage is that even if the microphone is a certain distance from your mouth, it will pick up your voice well. However, it also picks up ambient noise, and if the speaker is in the same room as the microphone, it also has the disadvantage of increasing the likelihood of feedback.
Microphone with low sensitivity
Microphones with low sensitivity pick up less noise, so you can clearly announce your voice even in noisy environments. Instead, you must always keep the microphone close to your mouth.
Another advantage is that it is difficult to pick up ambient noise and reverberation, so feedback is relatively unlikely to occur even if the speakers are in the same location.
