the Pulsar 30 sound level meter and real-time analyzer. It runs
on a PC under MS Windows 95 or later and provides the following
features:
- Download Data from the sound level meter
- Store measurements in folders for convenience
- Enter Comments and Notes for each measurement
- Display measurements individually or in a tabular format
- Graphical display of Time History
- Print reports
- Exposure calculations for occupational noise applications
- Enhanced Export functions (see below)
Advanced Features
- Select Hearing Protection - calculates the "level at the
ear" based on assumed protection given by hearing protector
database
- Calculate NR & NC figures from 1/1 Octave Band data
- Graphical display of 1/1 Octave Band measurements
 Broadband
Measurements
Broadband 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.
Frequency Measurements (Octave Band)
For Frequency Measurements made using 1/1 Octave Band Filters,
the information is displayed as a bar graph, with the numerical
data shown on the left. Comments and notes can also be entered for
future reference.
Individual Frequency bands can be highlighted using the cursor.
A and C Frequency Weightings can be applied by the software.
Analyzer also calculates and display NR and NC values
and curves from 1/1 Octave Band Data.
Calculation of 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.
Hearing Protector Selection
Where 1/1 Octave Band Measurements are available, the Analyzer
software can calculate the assumed protection from a range of Hearing
Protector products from a database. The results can be filtered
to remove, for example, protectors that do not reduce the noise
level at the ear to below 85dB(A).
The database of hearing protectors can also be updated with new
information as and when required.
Exporting Data
The Analyzer software can export data in a wide range
of formats. The supported formats are:
- Microsoft Excel
- Microsoft Word
- RTF
- HTML
- Text File
- XML
- DBF
- CSV
- DIFF
- SYLK
- LaTex
- SQL
- Windows Clipboard
In addition to the basic file format options, the data can be formatted
in a number of ways depending upon the export options, including
where appropriate fonts, colours, headers and footers, dates and
file extensions. For full details please refer to the Help file
provided with the Analyzer software. |
