WHAT MAKES A COMPRESSOR QUIET?
Terms like quiet, silent, quiet and the like are often seen in the market. But what does it really mean and what is really quiet?
Conventional compressors often have a sound pressure level (LpA) of over 80 dB (A), which corresponds to the sound pressure level when standing at the curb and a truck driving past. Long-term exposure to 85 dB (A) is the EU limit for being at risk of serious hearing damage.
The sound pressure level (LpA) from Nexo Air’s quiet compressors is between 53 and 62 dB (A), which corresponds to ordinary and loud speech. 3 dB corresponds to a doubling of the sound level pressure. This means that 63 dB is double of 60 dB, not 120 dB.
Suppliers of low-noise compressors state too optimistic figures that are not measured according to a well-defined standard. It is therefore not uncommon to experience a big difference in the perceived sound level of 2 compressors with the same specified noise level.
The sound levels (LpA and LwA) of our compressors are all measured according to ISO 2151. This means that you can be absolutely sure that a Nexo Air compressor is exactly as quiet as we promise.
