| The
Oregon Aero® HushKit® System and SoftSeal® Ear
Cushions perform significantly better than the best-performing
ANR
headset in the 700-7000Hz range. |

| Oregon
Aero test data numbers consistently dip below the desired
85dB level. |

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. |
| 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. |
