If the microphone comes closer to the mouth, the microphone signal becomes not only louder, but even more voluminous or bass-heavy. This stronger emphasis of low frequencies is called proximity effect. Since this effect is quite pronounced, it can even be used to specifically alter voice recordings. The greater the distance to the microphone, the thinner the recording sounds. If the distance is reduced, the recording becomes muffled.
Our TG V96, for example, is the ideal microphone for close-up, high-quality vocal performances, the TG D71, on the other hand, for optimal sound recording in the bass drum and the MC 930, in turn, for choir recordings from a greater distance.
