February Newsletter 2013 - Sound Level Meters - The Castle Range - Who has the loudest car at Instrument Choice? We decided to put one of the castle meters to the test with this month’s experiment by using it to test who had the loudest car at the Instrument Choice office, needless to say some enthusiastic revving occurred and the loudest car was proclaimed, check the experiment below to see who contributes most to the noise pollution on our roads. Remember; if you have any questions regarding tests you need to conduct or specific instrumentation please give us a call. Until next month... Tyson Grubb |

The development of their products is geared entirely around making your life easier with logical user interfaces and tailored information. With meters, dosimeters, calibrators and kits meeting both Class 1 and Class 2 standards Castle have the product to suit.If your primary goal is to notify workers that a noise hazard is present this is precisely where the Castle dBalert Vibrating Personal Noise Activated Warning unit comes into play. Perfect for safe work requirements or just for your employees and your peace of mind. It is specifically designed to activate only when the noise exceeds a pre-set level. This will warn your workers that they are working in a hazardous environment and to put their hearing protection on. The dBAlert utilises an Ultra-bright warning LED that is designed to catch the wearer’s attention, it also includes a vibrating alert which means there won’t be any excuses that your employees couldn’t see the alarm. When you want to get serious about industrial and environmental logging Castle delivers. The GA6226 Class 2 Industrial/Environmental Sound logging meter provides the essential measurements required in a number of applications and is well suited to carrying out Noise Risk assessments along with the majority of environmental assessment work. With the ability to measure a range of parameters including Leq (equivalent continuous level) both in ‘A’ and ‘C’ weightings, along with Cpeak, 5 selectable percentile values (Ln’s) and sound exposure (LE) and data log them simultaneously into its 10,000 point data memory for future analysis makes it a very powerful meter indeed. If you need a Class 1 meter to comply with certain regulations Castle offers the GA116B that can be coupled with the GA607 Class 1 Calibrator to form a formidable package at a price that won’t break the budget. | |||
This test is performed to determine if cars are quiet enough to be roadworthy; if a car registers a result of 90dB or higher it is not considered roadworthy. Results    The Silver Arrow - 79.3dB The Gold Nugget - 77.7dB The Beast - 80.7dB The Subaru (the beast) gave the highest sound level reading of 80.7dB. The Suzuki gave a reading of 79.3dB and the Hyundai gave the lowest reading at 77.7dB. Conclusions All of the cars gave readings which were less than 90dB which means that they passed the test. The beast confirmed its reputation as the loudest car in the parking lot. | |||
