Product overview
Description
Rectangular sound attenuators absorb airborne noise through acoustic splitters and casing-lined passages. Insertion loss varies by octave band, while pressure drop depends on open-area ratio, length and air velocity. Indigo Sky coordinates casing dimensions, splitter thickness and acoustic media facing to achieve the required noise target without sacrificing fan performance.
