sE Electronics Reflexion Filter Pro - MULTILAYER ANTI-REFLECTIVE FILTER FOR MICROPHONES

(This text is machine translated) Reflexion Filter is a portable device for recording live sound sources with a reduced external environment: the main function is to obtain a "dry" recording of a vocal part or an instrument. It therefore becomes a fundamental tool especially in studios that do not have a correct acoustic treatment, but it can also be used for shooting from the control room. Reflexion Filter has 6 main layers: the first layer consists of a reinforced aluminum grille that allows the sound to pass through an absorbent wool layer. The sound waves then pass through an aluminum sheet that helps dissipate the energy by interrupting the waveforms of low frequencies, and then pass into an air space maintained as such by the rods that cross the various layers. The air gap acts as a real acoustic barrier. The sound wave then passes to a subsequent layer of absorbent wool and then through another aluminum grille which absorbs and diffuses the remaining acoustic energy.
