Noise Control

European legislation has reduced allowable noise levels by 5 dB

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.

doseBadge Personal Noise Dosemeter

ImageThe doseBadge is the unique way to measure Occupational and Industrial noise exposure. Different to a traditional Noise Dosemeter, the doseBadge has no cables or buttons, and is controlled, via an InfraRed link, from the RC:110A Reader unit.

The doseBadge has no buttons or controls and is contained in a robust metal case which prevents damage to the unit. The doseBadge logs, measures and stores noise data throughout the measurement and this data is downloaded to the Reader unit for review and analysis.

By eliminating cable and controls from the doseBadge, the user can be sure that the person being measured cannot have tampered with the measurement and that the data is valid. The CR:110A version of the doseBadge has been designed to meet the needs of the new EU Physical Agents (Noise) Directive as well as a range of other noise measurement standards.
