connect sound level meter to computer

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.
