    • "For whom the deci Bells toll" by tigerpaw on 1/2/2013

      Quality:

      This unit is fairly easy to operate, but setting the time was a #@%&^% bear. Once you make it through that (it was somewhat perplexing), it's relatively easy to use. I've taken it out at night and recorded the dB ratings of a local geothermal plant. Measuring frequencies would be useful, as LFN (low frequency noise) is known to cause health problems. The tripod that comes with it may be adequate for a small digital camera, but I'd hesitate to use it with the sound meter.
