Acoustic Sensor placement
The Acoustic sensor has a small black arrow on the front (item 1 in figure below), when
placing the sensor the black arrow should point forward to the anterior of subject’s body.
Ensure placement site is hair-free, clean of debris, and dry prior to sensor placement.
Use an alcohol swab to clean the neck area, if needed.
The sensor pad (item 2 in the figure above) should be placed to either side of the larynx,
in the area just above the thyroid cartilage and below the jaw line (see figure below). Ensure
that there are no skin folds under the sensor pad.
