1. INTRODUCTION

The CEL-310 Dose Badge is a unique solution to problems associated

with the measurement of personal noise exposure. It is controlled and

downloads data via infrared signals and in consequence needs no

external controls or cables. This allows it to be used in situations where

the wearer is working in confined spaces, or where there is a risk of

cables becoming caught in machinery.

The Dose Badge can be configured to make measurements

according to ISO or OSHA standard, where it provides the following

information.

Run time Duration of the measurement,

/L Average sound pressure level during the

measurement period,

/ TWA Daily personal noise exposure,

% Dose Noise exposure as a percentage of a preset

total,

Exposure Sound exposure in Pa

h (Pascal squared hours),

Peak Exceeded Whether 140 dB(C) Peak has been exceeded.
