It comes with an on and off switch for this purpose. After measurement, it displays all the data on its screen for easy analysis. The device can display various variables such as The A weighted Leq or average noise level and the C weighted Peak value. The C weighted Peak value is used for the assessment of impulsive noise sources.

Assessor Models 81A or 82A also has a unique display which shows the estimated exposure duration, which calculates the noise exposure that would be achieved if the measurement was made over a longer period displayed in terms of LEX,8. The device is available in non data logging version. This version is useful in the cases where manual reporting is required.
