Hardware
Introduction
The Sound Sensor is designed to be used with a PASCO
computer interface to make measurements of relative
intensity of sound.
The built-in sensing element of the Sound Sensor is an
electret condenser microphone, which consists of an
electret membrane, metal electrode, and field effect
transistor that are in an efficient configuration yielding
superior signal-to-noise ratios (>60 dB) and excellent
frequency response (20 to 9,000 Hz).
Two stages of amplification are provided to condition the
low-level signal from the microphone for input into the
PASCO computer interface. The output from the sensor is
bipolar and ranges between ±10 volts. The Sound Sensor
can detect voltage levels as low as 0.0005 volts,
corresponding to sound levels that are barely audible to the
human ear. Sound levels ranging from classroom
background noise (45 dB) to levels exceeding 100 dB are
easily detected with the Sound Sensor.

The separate Mini Microphone is a sensitive. wide-range
electret condenser microphone with a protective foam
cover (removable). Its frequency range is 20 to 9,000 KHz
and its cable is approximately 1.5 meter long. The 3.5
millimeter phone plug connects into the phone jack on the
top of the Sound Sensor.
The Mini Microphone allows the Sound Sensor to be used
with the PASCO WA-9894 Resonance Air Column with
Speaker. When the Mini Microphone is plugged into the
Sound Sensor, the sensor’s built-in microphone is turned
off.
The sensor has an “auto ID” feature when connected to a
PASCO 550 Universal Interface or 850 Universal Interface.
The PASCO data collection software automatically
recognizes the sensor if the sensor is connected to these
interfaces.
NOTE: The Sound Sensor can be used with the PASCO
750 ScienceWorkshop Interface or 500 ScienceWorkshop
Interface, but the “auto-ID” feature will not be active.
The Sound Sensor can be plugged directly into the PASCO
interface or can be connected to the interface with the
included 8-Pin DIN Extension Cable.

options and to check for the latest versions.
Recommended Items
Set Up the Hardware
Connecting the Sensor to an Interface with
the 8-Pin Din Extension Cable (UI-5218)
•Connect one end of the included 8-Pin DIN Extension
Cable into the DIN plug on the end of the sensor.
•Connect the other end of the 8-Pin DIN Extension
Cable to an Analog Port on the 850 Universal Interface
or 550 Universal Interface.
•NOTE: If you use the older versions of the 8-Pin DIN
Extension Cable (CI-6516 or those supplied with
ScienceWorkshop sensors prior to 2012, the auto-ID
function will not work.
•NOTE: The Sound Sensor can also be connected
directly to an analog input port on the interface.

Mounting the Sensor
The Sound Sensor housing
includes a threaded hole
(1/4-20) on the bottom side.
Screw a Sensor Mounting Rod
into the threaded hole, and use
clamps and support rods to hold
the sensor in place.

•In the software, select Hardware Setup in the Tools
palette to open the Hardware Setup window. In the
Hardware Setup Window, check that the Sound
Sensor icon is connected to the interface icon.
•Select Hardware Setup again to close the window.
•Select an Oscilloscope (Scope) display from
the Display palette.
•In the Scope display, use
the <Select Measurement>
menu on the vertical axis to
pick a measurement to be
shown, such as Sound
Intensity (V).
•In the Controls palette of
the Scope display, click
“Continuous Mode” to open
the menu. Select “Fast
Monitor Mode” from the
menu.
•The “Record” button changes to “Monitor”,
•In Fast Monitor Mode, the Scope display allows you to
