Models SE and DL

Analysis type

All SoundPro SE/DL instruments are capable of anal yzing sound signals over
the full bandwidth of the instrument also referred to as “broadband
measurement”. If your instrument comes equipped with a filter, it can perform
an octave or a third-octave analysis, or both, dependin g upon the type of filter
installed. You can vary the analysis type between sessions, and the anal ysis
type selection remains constant throughout the ses sion.
Analysis types are identified in SoundPro SE/DL b y the following names:
• SLM - Broadband measurements
• 1/1 - Octave filtering
• 1/3 - Third-octave filtering

• STI-PA -Speech Intelligibility

Logging explained
Although you can view the current sound pressure le vel at any time that the
instrument is operating (See “Bar Chart and Filter ed Bar Chart” on page 67),
most measurements are reported for d ata obtained over the entire course of a
study or session. In some circumstances, however, you may want to save
intermediate measurement results. The SoundPro DL logging option provides
you with that capability.
With logging enabled, you can save selected measur ements at fixed intervals
during a session. You can set logging to occur as ofte n as once per second or
as seldom as once per hour. Once the logging charac teristics are determined,
the setup remains the same for the duration of the ses sion.
Logged data is automatically saved to the instrum ent’s memory card and can
be viewed in QSP II (“Information screen” on page 8).
NOTE: You must use a compatible SD card. For information about
replacing the SD card, see “Compatibility” on page 117.

The Display

The transflective LCD display contains an area on the top of the screen for
indicators including run, pause, stop icons and a run time clock. The middle
of the screen contains a fine resolution of pixels in which data is displayed
