This is dependent on the type of work that you do. If you work in a small workshop or out of your garage then realistically you want to make sure that the air compressor that you choose is not overly loud. Luckily the above-mentioned air compressors will only reach a decibel level of 80 maximum. This will ensure that you can still hear any conversation that may be happening around you but also just not be an annoyingly loud air compressor.
