6. Noise Attenuation
This product has been tested to European Safety Standard EN352-1:2020 and ANSI S3.19-1974 standard for hearing protectors. It provides a Single Number Rating (SNR) of 28 dB and a Noise Reduction Rating (NRR) of 23 dB.
ANSI S3.19-1974 (NRR)
The level of noise entering a person's ear, when PROHEAR EM016 earmuffs are worn as directed, is closely approximated by the difference between the A-weighted environmental noise level and the Noise Reduction Rating (NRR). Improper fit of this device will reduce its effectiveness in attenuating noise.
| Frequency, HZ | 125 | 250 | 500 | 1000 | 2000 | 3150 | 4000 | 6300 | 8000 | NRR | CSA Class |
|---|---|---|---|---|---|---|---|---|---|---|---|
| Grand Mean Attenuation, dB | 21.2 | 24.5 | 26 | 29.8 | 30.9 | 36.2 | 38.7 | 36.7 | 33.9 | 23 | BL |
| Standard Deviation | 3.1 | 3.9 | 2.1 | 2.8 | 2.6 | 2.9 | 2.9 | 4.2 | 3.1 |
Example:
- The surrounding noise level measured at the ear is 100 dB.
- The NRR of PROHEAR EM016 is 23 dB.
- The noise level entering the ear is approximately equal to 77 dB.
Please note that the NRR is based on the attenuation of continuous noise and may not be an accurate indicator of the protection attainable against impulsive noise, such as gunfire.
EN 352-1 (SNR)
| Frequency, HZ | 63 | 125 | 250 | 500 | 1000 | 2000 | 4000 | 8000 |
|---|---|---|---|---|---|---|---|---|
| Mf(dB) | 18.7 | 18.2 | 21.8 | 25.5 | 30.7 | 30.4 | 37.7 | 33.9 |
| sf(dB) | 3.2 | 2.7 | 3.7 | 3.1 | 2.5 | 1.8 | 3.1 | 3.0 |
| APV(f) | 15.5 | 15.5 | 18.1 | 22.4 | 28.3 | 28.6 | 34.6 | 30.9 |
Summary Values:
- SNR = 28dB
- H = 30dB (Hearing protection estimation for high frequency sounds, f ≥2000Hz)
- M = 26dB (Hearing protection estimation for medium frequency sounds, 500 Hz <f< 2000Hz)
- L = 21dB (Hearing protection estimation for low frequency sounds, f ≤500Hz)
