OHROPAX Color 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 Color softens the sound at this frequency by 30.1 dB (APV). The remaining noise pollution is 69.9 dB. OHROPAX Color is suitable because the value is lower than 85 dB.
Product information
Materials: PU flexible foam
Color: A selection of random colors
Properties: Anatomically formed ear plugs which, when softly pressed, gently expand to fit the auditory canal. The slightly rough surface also improves the positioning.
General safety precautions
Reusable ear plugs to be shaped before use, in compliance with the standard EN 352-2:1993.
Tested by FIOH (No. 0403), 00250 Helsinki, Finland.
1. Carefully insert the ear plug in accordance with the directions for use.
2. In noisy areas ear plugs must be worn constantly.
3. Each ear plug can be cleaned up to 5 times and then reused. After use, clean the ear plugs externally with warm water and mild soap. Do not wring out. Then leave to air dry for 48 hours.
4. Only use clean, dry and externally undamaged ear plugs.
5. This product may be affected by certain chemical substances. Further information can be requested from the manufacturer.
Warning: Failure to comply with these directions may considerably impair the protective effect of the ear plugs. |
