Supervisor is a software package for health and safety specialists. The package supports all Svantek instruments for the health and safety market.
The Supervisor is designed to meet the needs of diﬀerent users. In the case of simple applications that only require the analysis of the main results such as LAeq, LAFmax and Lcpeak, the program oﬀers quick previews and reporting without the necessity of opening data ﬁles. More advanced applications are handled within sessions where the user can choose the type of analysis to be performed. Those who draw up noise or vibration reports on a daily basis will appreciate the report templates, which once created can be applied to different sets of measurement ﬁles.
Each instrument that is connected to Supervisor is remembered together with information such as the uploaded settings, the ﬁrmware version, as well as the calibration validity date and instrument clock time. When data is downloaded, they are automatically categorised by measurement time and assigned to the instrument’s serial number.
Simulation of changes of noise source emission
The Supervisor software gives tools to simulate hypothetical situations in which the noise differs from that which was measured. When selecting a data block it is possible to shift the data up or down for any given dB value. It is also possible to simulate a situation where noise is equal to a given dB level or completely removed from time history. The altered data is recalculated automatically and both the original and recalculated results are shown so as to answer the question “What if”.
Hearing protection selection in accordance with ISO 4869-2
Workers should wear hearing protectors if the noise or sound level at the workplace exceeds 85 decibels. The selection of hearing protectors depends on a noise level in the working environment. Therefore the selection of suitable hearing protector should be based on noise measurement.
Each hearing protector has attenuation characteristics expressed in units of three methods:
SNR Single Number Rating,
HML High, Medium and Low frequency method, using A-weighted and C-weighted sound measurements in the calculation
OCTAVES The most accurate method requiring measurement in 1/1 octave bands.
The Supervisor supports all three methods allowing users to build up the hearing protectors data base. The calculation is done automatically with selection of data files containing noise results required by selected method.
