CVSA Technology and Hardware Flashcards

What type of microphone is typically recommended for CVSA examinations to capture the clearest voice signal?

Answer: Unidirectional or directional microphone

Unidirectional microphones are recommended for CVSA examinations to minimize background noise and capture the subject's voice clearly.

Which component of the human voice does the CVSA system primarily analyze?

Answer: Inframonic frequency modulations

The CVSA analyzes inframonic frequency modulations (micro-tremors) in the voice that are produced by stress responses in the autonomic nervous system.

What connection type is most commonly used to connect the CVSA microphone to the examination computer?

Answer: USB

USB connections are most commonly used for CVSA microphones as they provide consistent digital signal transmission with minimal interference.

Which environmental factor most significantly interferes with CVSA voice recordings during an examination?

Answer: Background noise

Background noise can contaminate voice samples and compromise the accuracy of CVSA analysis, making a quiet examination environment essential.

What is the primary purpose of the CVSA software's real-time display chart?

Answer: To visually represent voice stress patterns in real time

The CVSA software display chart provides a real-time visual representation of the subject's voice stress patterns for the trained examiner to interpret.

What physiological system does CVSA technology detect changes in that manifest as voice stress?

Answer: The autonomic nervous system

Stress activates the autonomic nervous system, which causes measurable changes in the micro-tremors of vocal muscles that the CVSA detects and analyzes.
