In practice noise date are not always consistent. Noise at machines can stem from unknown sources. It is important to know what noise levels can be found in the system and what causes them. PRUFTECHNIK Condition Monitoring performs acceptance measurements of noise emissions and compares the results with the latest standards. If necessary, suitable measures for noise reduction are identified and recommended. Measurements are made with the data analyzer VIBXPERT and evaluated with DBSpectra and the software OMNITREND. Dominant noise sources can be identified using third octave or narrow band spectra.
“Achievable noise reductions, e.g. in gear drives, can be up to 5 dB: through measures on housings, up to 7 dB: through measures on rotors, toothing and housings and up to 10 dB: through secondary noise shields or enclosures” says Dr. Edwin Becker, Manager Service and Diagnostic Center.
