Porelle have a specific membrane which has been developed for Acoustics ‘Porelle Acoustic’. This is a microporous membrane which has excellent sound performance and provides a waterproof breathable option to acoustic protection.
The non swelling nature of this membrane prevents any contact with electronics which can cause static and sound distortion.
Porelle Acoustic has been tested for use in microphones and headsets. Original sound signals have been recorded without the use of Porelle Acoustic and then with the membrane. The 2 sound waves were compared and the results were almost indistinguishable, with little to no variation from the original signal.
Porelle Acoustic still provides the original sound quality, with low distortion whilst protecting electronics. This can be vitally important in rescue and military situations were sound quality is of utmost importance.
