OHROPAX Classic has high sound attenuation values across the entire frequency range.
Checking the suitability of an ear plug:
1. Determine the level (dB) of the sound at the respective frequency (e.g. based on appliance documents).2. Subtract the APV (assumed protection value) from it.
3.The remaining value should be lower than 85 dB.
To simplify, you can also perform the calculation with the following (approximate) mean values:
• SNR (Single Number Rating, general attenuation)
• H (high, for high frequencies)
• M (medium, for medium frequencies)
• L (low, for low frequencies)
Example: At a frequency of 1000 Hz, an appliance generates a sound level of 100 dB. OHROPAX Classic softens the sound at this frequency by 22.6 dB (APV). The remaining noise pollution is 77.4 dB. OHROPAX Classic is suitable because the value is lower than 85 dB.
