Polygraph Exam Soundmasker

Product Code: AA87169
A quiet environment free of distractions is essential for polygraph testing. According to the American Polygraph Association Standards of Practice “conditions under which polygraph testing occurs are required to be free from distractions that would interfere with the ability of the examinee to appropriately focus during the examination process”.
The Polygraph Exam Soundmasker is an inexpensive, high-quality solution to noise distraction, by keeping the noise level at a minimum during polygraph examinations. The AA87169 is designed for quick and easy installation into small office zones, and is best utilized when areas of under 200 square feet (18.6 sq m) require dedicated control. A standard-size polygraph office requires one soundmasking unit in the corner nearest to the tested subject. The AA87169 can be suspended from the ceiling or mounted above a ceiling tile grid.
If necessary, multiple units can be networked to provide uniform soundmasking while locally powered by a central transformer. The Polygraph Exam Soundmasker contains a pink noise source, an active low-pass filter control, a soundmasking amplifier, and an 8” (20.3 cm) diameter loudspeaker with a magnet shield. These are enclosed in a 300-cubic-inch (4916 cubic cm) reinforced steel housing with stiffening ribs to reduce standing waves and metallic resonance.
The Polygraph Exam Soundmasker is the ideal device for examiners conducting polygraph tests outside of their office environment. The device will operate anywhere there is electric power. For protecting your test from potential eavesdropping, especially on the road, we recommend our Polygraph Exam Portable Eavesdropping Protection Package, model AA87170.
