Method for determining pilot stress through analysis of voice communication
Aviation, Space, and Environmental Medicine
|May 1, 1976
Summary
This study introduces a novel voice analysis method to measure pilot stress during emergencies. The vibration space shift rate (VSSR) quantifies stress by comparing voice patterns in normal versus emergency flight situations.
Area of Science:
- Acoustic analysis
- Aviation psychology
- Human factors engineering
Background:
- Traditional voice analysis methods are limited in aircraft communication systems.
- Assessing pilot stress during inflight emergencies requires specialized techniques.
- Understanding pilot stress is crucial for aviation safety.
Observation:
- A sound spectrogram can analyze the mean vibration space of a pilot's voice.
- The space between vertical deflections of vowel sounds, measured in micrometers, is key.
- This method allows for quantitative stress assessment.
Findings:
- The vibration space shift rate (VSSR) was developed to quantify stress.
- VSSR compares voice patterns during normal flight (standard vibration space: SVS) to emergency situations (emergency vibration space: EVS).
- The VSSR formula is VSSR = ((SUS-EVS)/SUS) X 100%, with phases categorized as normal, urgent, and emergency.
Implications:
- This method offers a new tool for objective pilot stress monitoring.
- Improved stress detection can enhance inflight emergency management.
- Findings may inform the design of more resilient aviation communication systems.
