Abstract
A microphone pop filter for attenuating plosive artifacts utilizes a substantially acoustically transparent material configured to define multiple airfoil surfaces that are oriented non-orthogonally relative to an axis defined between an audio source and a microphone diaphragm, with the substantially acoustically transparent material disposed intermediate the audio source and the microphone diaphragm and separated from the microphone diaphragm by an airspace. Plosive artifacts from the audio source may be deflected away from the microphone diaphragm by the airfoil surfaces to reduce the impact of such artifacts on the microphone diaphragm and the resulting electronic signal output therefrom.
