| Field of Application: The meteorological correction factor Cmet (DIN ISO 9613-2) must be taken into account in the calculation of the noise rating level, e.g. for the German “TA Lärm”. The correction factor includes a deduction dependent upon the meteorological conditions as well as the local situation between the noise source and the point of measurement. |
Description: This option allows the following weather data to be recorded synchronously with the noise level measurement: temperature, humidity, pressure, rain event, wind speed and wind direction. The wind direction is visualized as a direction-dependent color of a marker track. Technical Data| Features | - Synchronous recording with time signal, spectra etc.
- Temperature
- Wind speed and wind direction
- Humidity
- Rain event
- Atmospheric pressure
- ISO 9613-2:1996 (Acoustics -- Attenuation of sound during propagation outdoors -- Part 2: General method of calculation)
