The data-logging Sound Dose Meter is used to determine volume. The PCE-NDL 10 sound level meter is a handy measuring device that meets the highest requirements. In order to evaluate the measured data as best as possible, it is possible to use the internal measurement data memory on the sound level meter. In addition, the sound level meter has an SD card slot that enables the use of an SD card as an additional storage medium.
The sound data logger is not necessarily a device that has to be used for stationary monitoring of the noise level. After the measurements, the measurement data memories can be read out via the corresponding interfaces. This also enables analyzes. The sampling rate of the noise dosimeter is around one second and the storage interval can be set manually and is between one and 3600 seconds.
However, it must also be taken into account that the internal measured data memory of 16000 values will be filled quickly with a small storage interval and will then automatically overwrite the values measured first and thus delete them irretrievably.
