Minuendo Lossless Earplugs
Part of Minuendo’s patented innovation lies in the unique ability to adjust and steplessly tension the membrane. This provides a large range of varying attenuation. The Minuendo earplug lever simultaneously controls a combination of slit thickness, volumes and membrane tensioning to achieve natural sound across the adjustable range. The intricate interaction between membrane structure, tensioning, meshes and varying acoustic canal is calculated by using the Finite Element Method and equivalent electrical circuit analysis of the acousto-mechanical system.
