Features
  Q & A: We own one of your Tecpel 331 sound level meter data loggers which we used to measure the noise levels in patients rooms. The recording range was set 30-130 dBa, in fast recording mode. We had measurements of 28 dB despite the range of 30-130 dB. Could you please explain how this happen? Our findings will be published in a scientific journal hence we may need to explain this to reviewers. Your help is much appreciated Answer: Our sound level meter logger design can measure starting from 25 db but 30 dB is the limit of our published specification. Therefore, it is possible to have 25 ~ 29 dB, if your environment  is quite calm in a closed room.
