This personal sound exposure meter (PSEM) is a self-contained noise monitor ideally suited for workers ‘on the go’.  The NoisePen does not require a Charger or Reader Unit – all interactions are done via USB to a PC and our analysis and reporting software Pulsar AnalyzerPlus.

  • All programming and key functions such as start-stop, set up and configuration of the device, download, view and store measurements are performed prior to or on completion of field measurements via the software Pulsar AnalyzerPlus. 
  • The calibration of the NoisePen is also undertaken prior to taking a measurement with its acoustic calibrator and verified and logged via the software.  The same process is carried out on return of the unit to your office.
  • Using the powerful AnalyzerPlus software, it is possible to schedule a timed measurement at a date and time of your choice. Conveniently, you can also repeat a selected pattern over a period of 7 days without having to reset the NoisePen.
  • Pulsar AnalyzerPlus software will provide a full map of ‘Time History’ information to help you determine when key noise problems occur during a worker's day.
  • All the data essential to meet compliance with occupational noise regulations is also available to view from the reporting facility such as: LAeq, LEP,d, % Dose and TWA. 
  • The additional ‘C’ weighted peak Time History allows you to fully assess risks from impulsive noise in the workplace.

We bought two NoisePen units to check how much noise our employees had on our construction sites. We wanted something that was dead easy to use but our workers couldn't mess about with. Because of the kinds of work we do we can't have cables or anything hanging about so these are great. We were shown how to use the software and just plug the NoisePen into a laptop on site. HSE inspector was impressed too.

As a noise consultant, I often have to assess the noise exposure of employees in factories and industrial sites. Sometimes this is over just one shift but I also need to do it over a working week for some industries. The NoisePen is great for this because it measures noise dose for a whole week without the need to download measurements and reset in between - this makes things more efficient for me as I can leave the noispen with an operator on a monday for example and pick up on a friday. I like it too because the noisepen itself is it - there's no additional chargers or readers needed. All in all a real gem of a product that makes my job a heck of a lot easier.
