The sound level meter connects to the computer using the
cable supplied. The Deaf Defier software will display all the
measurements that are currently stored in the meter's memory.
You can select the noise measurements to download or opt
to download them all. The measurements can be stored in separate
folders to help to organise your work. |
Once downloaded, the noise measurements are displayed in both
a tabular and graphical format. The numerical values for the measurement
are listed down the left side and include the time, date, duration
and measurement range along with the Time and Frequency Weightings
used for each parameter.
The Time History graph is shown on the right side. A zoom function
is provided to allow more detail to be shown on the graph.
Calculation of Noise Exposure
The user can enter a different exposure time from the measurement
duration, allowing the software to calculate the overall noise
exposure in terms of the LEP,d according to the EU Physical Agents
(Noise) Directive as well as many other occupational noise exposure
regulations.
Built-In Reports
The Deaf Defier software has a number of standard reports
to make the process of completing a noise survey as efficient
as possible.
The reports can be sent directly to a printer, to a JPEG image
file, to a PDF file for emailing or directly to many other file
format. |

Exporting Noise Measurements
The measurements can be exported in many formats. In particular,
the tabular data can be sent to Excel or Word format for further
analysis or inclusion in reports. If the standard reports that
are built into Deaf Defier do not satisfy your needs then the export
option gives all the flexibility that you need. |
