Natural Science Forum / Physics / Acoustics / June 2006Noise monitoruing during Lunch breaks
I need opinions about if neccesary take noise measurements during lunch, for worker dosimetry. I read a paper that said that in this time the measurement unit had to be paused. In my experience, lunch time is quieter than work time, then, isn´t relevant for results. Thanks estudioacustico@terra.cl wrote in news:1149008730.261511.151320 @i39g2000cwa.googlegroups.com: > I need opinions about if neccesary take noise measurements during > lunch, for worker dosimetry.

You want the daily dose and if necessary you may or may not include the time allotted for breaks.

Modern dosemeters give a time history of the noise exposure. This is essential unless you watch the people being monitored all the time. For various reasons, people might try to minimise or maximise the measured noise exposure. I have experience of both these, but a time history of the noise will usually pick up anything odd going on, and will of course allow you to separately account for the exposure during lunch break.

But we had some problems with clients and collegues about that. But, i think, generally lunch time, noise level are lower than work time, and these can be ignored. Noise Levels History is a very useful tool too. Thanks and luck If the sound exposure during the lunch is insignificant, then it will not add to the dose, so the indicated dose for the day will be correct, and TWA computed from that will be correct. However, instruments also commonly show an average level for the monitored period, and that level would be lower for a period including a quiet lunch than for a shorter period without the quiet lunch. >> Modern dosemeters give a time history of the noise exposure.

The original intent of this overall procedure was to determine the employer's liability in causing hearing damage resulting in hearing loss. What the employee did on his or her own time (recreation, lunch, home, etc.) was not a matter of concern to OSHA and the employer. Thus, lunch break noise exposure was and still is not to be counted. If you want to measure that separately, then do so. The general pinion has been that this noise exposure is small and of less concern. But as many point out, it is possible that the employee can be exposed to significant sound levels during that time. Ultimately, the measurement protocol referenced was aimed at producing data that could be used for noise reduction design and implementation. Thus, any off job task noise exposure becomes a red herring for noise control engineering and test. Angelo Campanula. |
