downloading noise measurements

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.
