OMARA : an effective solution that ensures excellent intelligibility as well as perfect absorption of damaging noise levels
OMARA - A communication system
OMARA has been developed for pilots and flying crew members in order to ensure a perfect intelligibility in very noisy environments. Fighter plane and helicopter cockpits experience very high levels of decibels. Unfortunately,pilots are not fully protected against the danger of these high volumes with the possible result of unrecoverable damage to the human ear. This situation leads to tremendous costs due to the extremely large aviation professionals who have experienced hearing impairement.
OMARA - A custom-made disruptive solution
OMARA is a custom-made for each user, patent-pending system of auricles out of silicone allowing a clear perception of the radio messages, a good protection against the internal noise of the cockpits of military aircrafts and helicopters. A filter acoustic valve offers an excellent perception of alarms and a good barometric transparency
OMARA is composed of ultra high-quality components (cables, connector, receivers, filters, auricles) which were carefully selected to ensure the maximum comfort and security for pilots
OMARA allows to dramatically increase the pilot's performance during the flight and ensures a sustainable hearing capability.
The customised silicone earplug 60 shore with Jrenum Filter LD18 green must fit perfectly to eliminate the background noise.

How to guarantee hearing intelligibility ?
Hearing intelligibility is a complex phenomenon that calls for detailed study in order to develop and deploy a consistent strategy. The most important part of the frequency spectrum is the intermediate region between 700 and 4000 Hz - this is the range that is directly linked to intelligibility. Acoustic cues, as they are known, play a key part here. Two types of technology are available : active (the active noise reduction technique) and passive (acoustic filtering), and the two can also be combined. The active noise reduction technique produces an efficient response in the low frequency range of the spectrum (100-300Hz). On the other hand, acoustic filtering is a simple and efficient way of eliminating noise across the whole range.
