The truth machine is based on two elements of the US Lie detector, the Psychlogical Stress Analyser (VSA) and the Voice Stress Analyser (VSA). This clever little device measures micro tremors in the sounds produced in the vocal chords to determine if someone is telling you less than the whole truth.
The results are analysed and displayed by columns of green and red LED Lights.
Will measure voice, TV or Radio.
Also great for party games.
