While interviewing a person we use “MIC” and hold it in front of the subject.
But today we don’t know who has been; knowingly or unknowingly, contacted with Corona Virus. Therefore we are at risk of contracting it ourselves. Also other subjects who speak on the same “MIC” also are at threat as the Virus may land on “MIC” and your hand during the interview and afflict upon those handling the same unsanitised “MIC”. You can also be at grave risk along with your family, friends and colleagues.
So either sanitise the “MIC” or discontinue its use. Also make sure to use a mask & hand gloves during interviews. Ensure safety of yourself and others.
Any camera can capture voice from 3 meter distance.
