Question 1

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

Accepted Answer

Unidirectional or directional microphone

Answer

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

Question 2

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

Accepted Answer

Inframonic frequency modulations

Answer

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

Question 3

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

Accepted Answer

USB

Answer

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

Question 4

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

Accepted Answer

Background noise

Answer

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

Question 5

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

Accepted Answer

To visually represent voice stress patterns in real time

Answer

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