Filtered Sonic Defenders use established,non-electronic technology to reduce dangerous noise while allowing the hearing of safe-level conversations, commands, and ambient sounds.
- Loud, potentially harmful sound waves enter the filter.
- Sound waves above 85dB hit the ridges inside the filter.
- These sound waves reflect off the ridges of the narrowing walls and cancel themselves out.
- Dangerous sound levels are reduced, and safe levels pass through.
- The louder the sound, the more noise gets canceled
