Haribo
The Health and Safety Advisor at HARIBO says 'The Nova is a fantastic piece of equipment. It allows me to take quick readings and produce the relevant reports and make PPE comparisons easily. As well as saving me considerable time, the clear, real-time screen lets me show and explain to the staff the noise readings in their area as it happens. This is the best tool I have had in cultivating a positive attitude in the staff toward managing their own noise exposure and wearing the hearing protection correctly'.
Top Performance from Pulsar Nova 45 in TV Studio Project Allows the Show to Go On!
The noise levels in TV studios have to be low and thus when it comes to acoustic measurements of plant above them then speed is of the essence so that the show can go on. Graham Ellicott, noise consultant, recently had to carry out a number of measurements in a ductwork system above a TV studio that supplies programmes for channels that are available via BSkyB. The noise measurements required the removal of hatches in the ductwork and this process plus the extra noise generated by their opening could have been difficult to deal with had it not been for the Pulsar Nova 45 which can measure many different functions simultaneously. A small ‘window' of time (approximately 10 mins between takes) was all that was available for the whole measurement process and the Nova 45 easily took this in its stride. Graham commented "In the past, I've used other meters that would have required at least 30 minutes for all of the measurements but because of the Nova 45's ability to measure simultaneously the whole process was completed within the 10 minute window thus saving me and the client time while allowing the show to go on!"
