Noise dosimetry measures the amount of noise workers are exposed to over their 8,10, or 12 hour work day. Knowing how much noise workers are exposed to is essential to protecting their hearing. To do that well a dosimeter must provide comprehensive information under varying conditions, in multiple locations and attached to different wearers.

Sound energy is commonly expressed in decibels (dB) measuring sound level pressures over a period of time and averaging them is called a dosimetry test or determining an LEQ (time weighted average). If you want to know the noise levels employees are subjected to, you need to take dosimetry measurements. From the results you can determine which dB Blocker™ best suits your workers.
