Models and options
SoundPro®Sound Level Meters Models SE and DL
Introduction
The SoundPro SE and DL series of Sound Level Meters (SLM) from TSI are advanced instruments with
highly adaptable characteristics. This manual explains the features and functions of all models in the series
and points out distinctions between the models.
Models and options
There are twelve models in the SoundPro SE and DL series meters. The differences between models are
accounted for by three primary characteristics: accuracy of measurement, frequency resolution, and the
types of data stored. The table in Figure 1-1 summarizes the characteristics of all twelve models and
includes add-on features for Reverberation, Speech Intelligibility and Acoustic Spectral Curves.

2Frequency resolution
Octave bands
SoundPro®Sound Level Meters Models SE and DL
Frequency resolution
The sounds we hear are rarely pure tones at a single frequency but rather a mixture of frequencies of
varying amplitudes. Some sounds, such as a whistle or a horn, have frequencies concentrated in relatively
narrow regions of the audio spectrum, which ranges from approximately 20 Hz to 20,000 Hz. Other
sounds, more generally thought of as noise, include components from many regions of the entire spectrum.
When analyzing sound as noise, we usually are concerned with the total impact of the sound signal. In
other words, we are usually satisfied with a broadband measurement of sound in the environment. When
we are seeking to isolate a sound from other sounds, for instance to detect the source of a sound or to
measure how much particular sounds contribute to the overall sound level, we may want to look at the
frequency components of the sound.
Octave bands
The ability of an instrument to separate a signal into its frequency components is known as a spectral
analysis. In sound pressure measurement, the audio spectrum is divided into adjacent frequency bands
called octaves, where the center frequency of each octave band is twice the center frequency of the octave
band directly below it. There are eleven octave bands in the audio spectrum.
Figure 1-2 illustrates the relationship between the bandwidth of a typical sound measuring instrument and
the octave bands that span the audio spectrum. Note that the highest and lowest octaves at 16 Hz and
16 kHz lie entirely within the bandwidth of the instrument.
Figure 1-2: Octave bands
Level

3Frequency resolution
Third-octave bands
SoundPro®Sound Level Meters Models SE and DL
Third-octave bands
Each octave band can be divided into three adjacent bands called third-octave band. Because of the
logarithmic relationship between adjacent bands, the center frequencies of third-octave bands differ from
each other by 26%. For example, the center frequency of the next third-octave band above the 1000 Hz
third-octave band is at 1260 Hz. Figure 1-3 is similar to Figure 1-2 but shows the thirty-three third-octave
bands in relation to the instrument’s bandwidth.
Figure 1-3: Third Octave bands
Naming bands
Bands are conventionally named for their center frequencies in accordance with acoustical industry
standards. Table 1-1 (see below) identifies the SoundPro SE or DL models that have octave and third-
octave bands option with their exact center frequencies and their corresponding standardized names.

Analysis type
All SoundPro SE/DL instruments are capable of analyzing 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, depending upon the type of filter installed. You
can vary the analysis type between sessions, and the analysis type selection remains constant throughout
the session.
Analysis types are identified in SoundPro SE/DL Sound Level Meter by the following names:
SLM - Broadband measurements
1/1 - Octave filtering
1/3 - Third-octave filtering
STI-PA -Speech Intelligibility

5Logging explained
The Display
SoundPro®Sound Level Meters Models SE and DL
Logging explained
Although you can view the current sound pressure level at any time that the instrument is operating (See
“Bar Chart and Filtered Bar Chart”), most measurements are reported for data 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 meter logging option provides you with that capability.
With logging enabled, you can save selected measurements at fixed intervals during a session. You can
set logging to occur as often as once per second or as seldom as once per hour. Once the logging
characteristics are determined, the setup remains the same for the duration of the session.
Logged data is automatically saved to the instrument’s memory card and can be viewed in QSP II
(“Information screen”).
NOTE: You must use a compatible SD card. For information about replacing the SD card,
see “Compatibility.”
Physical Characteristics
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 both numerically and graphically. This is explained in further detail in Chapter 2,
“The Display and keypad”).
Hardware interfaces
The Hardware Interface Panel, shown in Figure 1-4, is located under a hinged cover in the base of the
instrument. The cover can be lifted by a tab at one side, and snapped shut again by closing and pressing
firmly at the center.

card should always be in place when you are operating the instrument. More information about operating
with the memory card can be found under “Memory card.”
NOTE: You must use a compatible SD card. For information about replacing the SD card,
see “Compatibility.”
USB port
Each SoundPro SE/DL instrument ships with a USB cable. One end fits the mini B port in the instrument.
The other end fits a standard USB connector on a personal computer. A USB connection to a personal
computer allows files to be transferred, settings to be downloaded to the instrument, and post-session
analysis to be performed in the computer using data files created in the instrument.
AC/DC port
Connect a cable with a standard 3.5-mm stereo plug to this jack to obtain AC and DC output signals.
Users are responsible for providing their own cable.
Power jack
DC power can be delivered to the instrument through the Power jack. Power will be taken from the
external source rather than the instrument’s batteries when the external source provides 8 to 16 volts DC
(300 mA minimum).
Two optional sources for this power are available: a switching power supply connected to an AC source
and DC power provided through the accessory jack of most automobiles. For the technical specifications,
see “Power sources” in Appendix A. Part numbers are given under “Optional parts” in Appendix A.
Auxiliary port
Use this port to connect the SoundPro SE/DL instrument to other devices. The two types of functions,
described below, are available through the terminals of this port. A pinout of the port is provided under
“Auxiliary connector.”
Digital I/O - A group of contacts within the port provides one, logic- level input and three, logic-level
outputs. See “Digital Outputs/Triggering” are information about configuring and using the triggers.
• RS-232 - A group of contacts within the port supports the RS-232 protocol for communication
between the instrument and other devices, such as a Global Positioning Satellite (GPS) receiver.
See “GPS” for information about configuring the port for this purpose.

Installing the preamp
SoundPro®Sound Level Meters Models SE and DL
Installing the preamp
The preamplifier is detachable for storage purposes or if you want to connect an extension cable for
distance monitoring.
Connecting to the instrument
Place the preamp connector over the mating
connector at the top of the instrument. Gently
press down while rotating the preamp until the
preamp connector drops slightly in place.
Figure 2-2: SoundPro & Preamp
1. While pressing the connector together to engage the threads, rotate the black knob clockwise
to secure the preamp to the instrument. It will fit snuggly.
Connecting an extension cable
Extension cables are available from TSI as options and are typically used to distance the instrument
body from the microphone to reduce distorting reflections from the instrument’s case.
1. Attach the cable to the base as if it were the preamp and then follow the steps above
“Connecting to the instrument.” Attach the preamp to the other end of the cable.
Microphone and accessories
The instrument is ordered either for Class/Type 1 or Class/Type 2 use. See “Distinctions between models”
for information about this classification. The microphones are treated differently for the two classes of
instruments.
