  • Affordable Hearing Protection Prescription
  • Automatic C-A measurement mode
  • Ideal for HML method of hearing protection calculation
  • Effective LED Indicator when in C – A mode
  • Hearing protection measurements have never been easier; The C-A mode ensures automatic measurement calculation
  • Expands the original concept of the basic Assessor for those with noisy work places that prefer an affordable but legal method of specifying suitable hearing protection measurements
  • Compatible with the outstanding ‘Analyser’ software package

    The Models 81CA & 82CA are the ideal instruments for those who do not want an instrument with 1:1 Octave Band Filters when the HML method (High, Medium and Low), is an established and accepted method of calculating hearing protection requirements.

    All hearing protection (PPE) should be supplied by the manufacturer with attenuation (reduction) values for each of the H, M and L values. By knowing the ‘C’ and ‘A’ weighted Leq values and the difference between them you can use either a spreadsheet or simple formula to select suitable hearing protection for your workforce.

    C-A Measurement Mode

    By just pressing the C-A button, the instruments will automatically switch to ‘C-A’ Measurement Mode. A Blue indicator shows that you are now measuring in C-A mode rather than the normal Broadband mode.

    The instrument will make an Leq measurement with dB(C) weighting (LCeq) and will continue until the average level has settled. When the level has settled, the instrument will switch to dB(A) and repeat the process with ‘A’ weighting.

    When this level has also settled, the instrument will display the LCeq, LAeq and in large digits the resultant LCeq – LAeq value on screen. Making this type of measurement has never been easier, as everything is done in an automatic cycle for you.
