Hey experts, does anyone know what the dB value for gearbox vibration represents? Vibration monitoring of Koenig & Bauer extruders’ reduction gears is carried out in decibels; does anyone know what these decibel values corresponding to vibration levels mean?

dB=20*lg(a/a0), where a is the acceleration you measure, and a0 is the reference acceleration
