TESTING PROCESS
Once the Sonomax Hearing Protection has been moulded and visually inspected for quality the Hearing Protectors are tested using a sophisticated, totally portable, testing process.
The moulded Sonomax Hearing Protector contains a sound bore which is simply a small hole through the protector which we use to measure the effective protection level. The Sound Bore is filtered or sealed at the conclusion of the test.
While wearing their new Sonomax Hearing Protection a specially designed microphone is inserted into the Protector's sound bore. The subject is placed in front of a speaker which will produce a calibrated pink noise sound signal.
The sound is measured simultaneously at the ear drum and externally. In a few seconds the test results are displayed on the operators screen for each octave band of human hearing from 125 to 8000hz.
The resulting protection level has been verified to be accurate by six independent laboratories around the world, including Australia. In Australia it has been tested to meet the Australian Standard AS/NZS 1270:2002.
Two tests a carried out per ear to double check the subjects own ability to insert the hearing protector to receive the same result.
A detailed report is then produced for each person that documents the protection level achieved. |
