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 organize 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.
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. Typical reports are:
Environmental and Community Noise Surveys The
standard reports can show a graph of the noise level over
time, graphs of parameters such as the Leq and Ln showing
the noise trend over long periods and tabular summaries of
the levels measured.
Noise at Work Reports For those using the
meter for noise at work measurements, the software can calculate
the LEP,d from multiple sources and produce a simple report
of the assessment made.
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 formats. |

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. |
