Dosemeter or Sound Level Meter?
For noise at work applications a dosemeter or a sound level
meter can often be used to achieve the same result: the measurement
of noise and calculation of a worker's daily noise exposure,
or LEP,d.
In some workplaces it is better to use a hand-held sound
level meter, while in others the best option is to use a
noise dosemeter mounted on the worker. Here are some guidelines:
Use
a dosemeter (or personal sound exposure meter, PSEM)
when the worker is moving around continuously, or between
many different locations. A dosemeter is also a better option
when the worker is in location that makes the use of a hand-held
meter difficult, such as confined spaces or the cab on moving
machinery. Finally, a dosemeter can take much less time to
use as you do not have to follow the worker around while
making measurements. This is particularly important when
monitoring the noise exposure of large numbers of workers. |
