A NetBox creates about 20 MByte data per day. Occasionally (normally less than once a month) a firmware update is distributed with a size of 250 MByte. A SIM card monthly data volume of 1 GByte is recommended.
If required, utilize the XL2 and NetBox in Gateway Mode.
The audio files are available for download and import into the Data Explorer software for playback synchronized with the level data.
“Audio files on alarm” are available in case the measured noise level exceeds the preset limit. For example the noise level LAeq exceeds the limit of 60 dBA for the 5 minute time interval.
The XL2 Sound Level Meter records the audio data locally on the meter throughout the ongoing measurement. In case of any exceeded limits, NoiseScout detects the three periods with the highest sound pressure level within the time interval and stores the audio data of these periods on the server. The length of any audio file on alarm is 10 seconds.
The audio file is offered as a WAV file with ADPCM compression and automated gain control. The sampling frequency is 12 kHz, thus offering good quality audio reproduction.
