Occupational noise - assessment and control

Pollution Control Consultancy and Design (PCCD) provides outstanding occupational noise surveys:  our surveys, unlike most of the others readily available now, do not only finger possible problems, but also effectively resolve them by developing or helping you to develop thorough administrative and/or engineering noise reduction programs.

Our engineering noise reduction programs (modification of noisy equipment and/or modification of buildings and/or enclosures accommodating noisy equipment) are based on state-of-the-art measurements of the sound intensity, which, unlike common measurements of sound pressure, allow to precisely locate and rank all noisy parts of mechanical plants (worn-out bearings, vibrating panels, cooling fans, gear boxes, supporting structure).
 

For details, please download (print out): our brochure relating to occupational noise.

Our occupational noise services include:

   1.  noise measurement and assessment with factory-/NATA-calibrated, Class 1:  
          -   Brüel & Kjær (B&K) Real-Time Sound Analyzers types: 2250 and 2270; and  
          -   Svantek unique Real-Time Sound Analyzer - Dual-channel Acoustic Dosimeter type SV 102A:

  2.  verification of compliance with the Work Health and Safety Regulation 2017 and Australian/New Zealand Standard:
       Occupational noise management (AS/NZS 1269: 2005);

  3.  complete, apt and cost-effective engineering noise reduction program, based on state-of-the-art measurements
       of the sound intensity, that may include:  
         -   design of noise barriers, enclosures and silencers;  
         -   design of noise barriers, enclosures and silencers;  
         -   modification of buildings, rooms and/or enclosures accommodating noisy equipment;
 
  4.  accurate (based on noise frequency spectra) selection of appropriate personal hearing protectors in areas
       where engineering noise reduction is impractical or cannot be implemented immediately;
 
  5.  formal written report that, in full, includes:
        -   discussion on occupational noise criteria;
        -   complete results of noise measurements, including octave band and/or third-octave band spectra of noise;
        -   plotting of sound energy contours (isopleths of L_Aeq) over the "factory floor";
        -   detailed discussion of measurement results;
        -   administrative and/or engineering noise reduction programs; and
        -   selection and/or verification of appropriate personal hearing protectors.
