Hello experts, I am reading an article I can´t quite understand, regarding something called "muffling". My question is. Whats muffling? is it a circuit or piece of electronics inside the microphone? is it a physical isolating mount or fabric inside the microphone's housing? This is what it says: "Microphones are muffled with one objective: flatten their frequency response. Muffling is a resource by which vibrations are reduced. It reduces vibration of the sound that enters the device. Muffling produces noise and reduces the microphone's sesibility. A very effective way to reduce noise is to decrease or even eliminate muffling on the microphone." Thank you for your replies!
