Waterproof sound permeable film is a kind of waterproof material made of ultra-thin film for acoustic components. Currently, there are three common materials with different properties and application environments. Let's take Microvent for example: there's the MVA-IM series, the MVA-DS series, and the MVP series. MVA-IM series waterproof, breathable and sound permeable, that is to say, this material can be waterproof, breathable and sound permeable, low sound loss, good water resistance! MVA-DS series refers to waterproof, sound permeable, breathable, with high waterproof performance, general sound loss characteristics. The MVP series is waterproof and breathable, but has low water resistance. Generally speaking, is any direction splashing water has no harmful effect, low sound loss.

Microvent's sound-permeable material can be used in harsher environments (IP68) without compromising acoustic performance than conventional mesh (IP54). In addition, the material "breathes" and the pressure balance can suppress acoustic device bias and shell condensation resulting in sound loss and quality issues.
