* When comparing the test results, note that the reduction of sound pressure is calculated in a non-linear logarithmic scale. A 3dB reduction in overall sound pressure is equal to doubling the distance to the noise source. E.g., 20' from the noise source, less 3dB, would be equivalent to the sound level at 40' from the noise source. An additional 3dB reduction would create the sound pressure at 80' from the noise source; 3dB more would equal 160' from the noise source, etc.
WHAT DO THE CHARTS SAY?
In the mid-range frequency levels of 700-7000 Hz, the Oregon Aero® upgraded headset performs significantly better than the best-performing ANR headset. In fact, the Oregon Aero numbers reach — and significantly and consistently dip below — the desired 85dB level. This is the sound frequency range that most contributes to hearing damage and loss.
