User manual NorCloud > Project > Sound Setup

All NorCloud measurements are set to have 1 hour synchronised measurements as the Global measurement values.

Level vs. time (L(t)), also known as time profile or electronic level recorder is a part of the basic functionality. Three time profiles are available;

•Profile A

•Profile B

•Moving

Profile A is the main profile from where the other two are extracted. Thus the period length must be set shorter than Global measurement, Profile B and Profile Moving. It can be specified in minutes, seconds or milli seconds and it must be a multiple of the Global measurement period length which is one hour.

The chosen sampling rate in Profile A is deciding what amount of credit points that will be deducted from your account periodically.

Global	is presented with one overall value per measurement function every hour in NorCloud
Profile A	provides a detailed analysis, this will always be active
Profile B	provides detailed analysis but with a lower resolution than Profile A.
Moving	provides a value for a time span that slides along with the measurement. It is updated with the same timing as Profile A, hence the moving window will move by 1 second if Profile A is set to 1 second. Default length of the moving window is 5 minutes.

The lowest time constant allowed is 25 ms.

If using a weather station, noise compass, frequencies or recording, the lowest time constant allowed is 100 ms.

If the number of network functions (e.g. A/C/Z-weighting, Leq/Lmin/Lmax, Fast/Slow/impulse combinations) with frequencies 1/1 or 1/3 octave bands are more than 3, the lowest time constant allowed is 1 second.
