Soundproof support membrane assembly |
| abstract |
PROBLEM TO BE SOLVED: To provide a membrane assembly which prevents the invasion of water, dust and other pollutants and allows air to pass through. An assembly 100 includes a porous polymer membrane 104 and a support layer 102. The porous polymer membrane 104 contains a plurality of pores. The support layer 102 includes a plurality of openings 106. Assembly 100 has an acoustic impedance with a phase angle of +45 degrees to -45 degrees over a frequency range of 50 to 20,000 Hz.
