Introduction
The SoundPro SE and DL series of sound level met ers (SLM) from 3M 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. The differences betw een
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 Intelli gibility and Acoustic Spectral Curves.

Octave bands
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

entirely within the bandwidth of the instrument.

Third -octave bands
Each octave band can be divided into three adjacent bands called thirdoctave 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 12 but shows the thirty-three third-octave bands in relation to the instrument’s
bandwidth.

Naming bands
Bands are conventionally named for their center frequencies in accordance
with acoustical industry standards. Table 1-1 identifies the SoundPr o SE or
DL models that have octave and third-oc ta ve bands option with their exact
center frequencies and their corresponding standardized names.

5 Logging explained
Models SE and DL
Analysis type
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 by the following names:
SLM - Broadband measurements
•
1/1 - Octave filtering
•
1/3 - Third-octave filtering
•
• STI-PA -Speech Intelligibi l ity
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” on page 67),
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 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” on page 8).
NOTE: You must use a compatib le SD card. For inf ormation about
replacing the SD card, see “Compatibility” on page 117.
Physical Characteristics
The Display
The transflective LCD display contains an area on the top of the screen for

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.
Figure 1-4: Hardware Interface Panel
Memory card slot
A Secure Digital (SD) removable memory card is shipped with each
SoundPro SE/DL instrument. The card should always be in place when you
are operating the instrument. More information about operating with the
memory card is given under “Memory card” on page 106.
NOTE: You must use a compatible SD card. For information about
replacing the SD card, see “Compatibility” on page 117.
USB port
A USB cable is shipped with each SoundPro SE/DL instrument. 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.
7 Physical Characteristics
Models SE and DL
Hardware interfaces
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 (300ma 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” on page 139.
• Digital I/O - A group of contacts within the port provides one, logic- level
input and three, logic-level outputs. See “Digital Outputs/Triggering” on
page 50 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” on
page 54 for information about configuring the port for this purpose.

Installing Batteries
Providing power
You can power the instrument with internal batteries or from an external power
source. There are two optional sources which include a universal power supply
9V/.66A 2.1 mm and an auto DC jack cable 12V. (See Optional Parts, in Appendix
A for more details.)
Installing Batteries
The instrument requires four AA-sized batteries. Disposable alkaline batteries
are satisfactory, but you may also use rechargeable Nickel Metal Hydride
(NiMH) batteries.
•
Rechargeable batteries ~ The instrument does not contain a recharging
circuit. Recharge batteries externally using the recharging device
available from 3M or a compatible device available elsewhere.
• Selecting batteries ~ Do not mix battery types or b atteries with
significantly different charge levels.
NOTE: To avoid possible battery leakage, remove the batteries when the
meter is not in use for prolonged periods.
To install batteries
1. With the back of the instrument facing up, push the release latch to pop
open the battery lid (Figure 2-1).
Figure 2-4: Installing batteries
2. Lift off the lid and set aside. Wedge out the four batteries.
3. Replace the batteries with fresh batteries, taking care that you orient all
batteries with the positive ends toward the base, as shown in the drawing.
