Noise Measurement Regulations

The dose Badge meets the requirements of both the American (OSHA) and European (ISO) measurement standards. As it is not actually possible to meet both at the same time, the dose Badge has two channels that can be set to measure both OSHA and ISO settings.

The dose Badge also meets the requirements of the US DOE, ACGIH, AICHE and MSHA regulations and guidelines.

The selection of which standard to measure by is done using the simple menu in the Reader. The dose Badges are shipped pre-configured to the relevant standard, so making the changes should not normally be necessary.

The most common settings are:

• 3dB exchange rate, no time constant and no threshold
  • This setting is ideal for many applications, including the European Noise at Work regulations.
• 5dB exchange rate, slow time constant, 80 dB threshold
  • Ideal for measurement to the OSHA regulations for occupational noise measurement.

Noise Dosimeters - Standards

The dose Badge system meets the following standards:

  ANSI S1.25:1991 Personal Noise Dosimeters

  IEC 61252:1993 Personal Sound Exposure Meters

To satisfy the OSHA measurement standards, the dose Badge measures the following parameters: LAVG, TWA and% Dose. The exchange rate is set to Q=5.

To satisfy the ISO measurement standards, the dose badge measures the following parameters: LAeq, LEPd, SEL, % Dose, Exposure Pa²h, Estimated % Dose, Estimated Pa²h.

It can easily be set to measure both OSHA style 5dB measurements and ISO 3dB measurements at the same time as it is a dual-channel dosimeter.
