Ans: Each type of microphone has its own polar pattern that decides the directions from where the microphone is going to pick up sounds. Lavalier mics are designed by using only directional polar patterns. These microphones are capable of picking up sounds from all the directions. If the quality of the microphone is a good one, then it is capable of opposing the background noise while recording the main audio with clarity and precision. One of the best examples of the usage of Lavalier microphones, is by celebrities who host events on live shows. Lavalier microphones are also known as Lapel microphones. Anchors from different shows pin these types of microphones upside down to prevent the recording of nasal exhalations while anchoring.
