CVSA CVSA Technology and Hardware 1 — Questions and Answers
Question 1: What type of microphone is typically recommended for CVSA examinations to capture the clearest voice signal?
- Omnidirectional microphone
- Unidirectional or directional microphone (Correct answer)
- Wireless Bluetooth microphone
- Built-in laptop microphone
Correct answer: Unidirectional or directional microphone
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?
- Pitch frequency
- Inframonic frequency modulations (Correct answer)
- Volume amplitude
- Vocal clarity
Correct 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.
Question 3: What connection type is most commonly used to connect the CVSA microphone to the examination computer?
- Bluetooth
- USB (Correct answer)
- 3.5mm analog jack
- HDMI
Correct answer: USB
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?
- Room temperature
- Background noise (Correct answer)
- Lighting conditions
- Room size
Correct answer: Background noise
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?
- To record the examiner's written notes
- To visually represent voice stress patterns in real time (Correct answer)
- To store subject biographical information
- To automatically calculate the final report
Correct 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.
Question 6: What physiological system does CVSA technology detect changes in that manifest as voice stress?
- The digestive system
- The autonomic nervous system (Correct answer)
- The skeletal-muscular system only
- The endocrine system exclusively
Correct 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.
