Presbycusis and Fitness to Fly
Aerospace Medicine and Human Performance
|April 25, 2020
Summary
Pilots with age-related hearing loss (presbycusis) can often maintain flight fitness. Most pilots evaluated received waivers, with many having no flight restrictions, indicating safe aviation activity is possible.
Area of Science:
- Aviation Medicine
- Otolaryngology
- Audiology
Background:
- Presbycusis (age-related hearing loss) can raise questions about pilot flight fitness.
- Evaluating hearing loss in pilots is crucial for aviation safety and career continuation.
Purpose of the Study:
- To analyze a case series of pilots with presbycusis.
- To discuss flight waiver decisions for pilots with age-related hearing loss.
Main Methods:
- Retrospective examination of medical files for 19 pilots referred for presbycusis.
- Assessment of flight fitness based on speech recognition in noise and audiometry results.
Main Results:
- 14 out of 19 pilots received flight fitness waivers.
- 7 of the waiver recipients had no flight restrictions.
- Only 5 pilots were denied flight fitness waivers.
Conclusions:
- Presbycusis does not automatically disqualify pilots.
- Flight fitness can be determined through specific audiological assessments, allowing for safe aviation activity with or without restrictions.
- Waiver criteria focus on speech recognition capabilities in noisy environments.

Respiratory System Abnormal Finding I: Inspection and Percussion
660
Respiratory system abnormalities are a significant concern in healthcare due to their potential to indicate underlying severe conditions like Chronic Obstructive Pulmonary Disease (COPD), asthma, and pneumonia. These abnormalities can often be detected through physical examination methods like inspection and percussion.
Inspection Findings
During an inspection, several findings may suggest the presence of respiratory distress or disease. Pursed-lip breathing, where exhalation is slowed by...

Pulmonary Function Tests (PFTs)
Pulmonary Function Tests are crucial diagnostic tools for assessing respiratory function, particularly in patients with chronic respiratory disorders. They comprehensively evaluate lung volumes, ventilatory function, breathing mechanics, diffusion, and gas exchange. These tests help diagnose pulmonary diseases and play a significant role in monitoring disease progression, evaluating disability, and assessing response to therapy.

In assessing respiratory abnormalities, palpation and auscultation are critical tools for detecting and interpreting various pathophysiological changes. These techniques provide insight into underlying disorders by evaluating tactile sensations and sounds produced by the respiratory system.
Palpation Findings
During a respiratory assessment, palpation can reveal several vital abnormalities:

Perception of Sound Waves
5.3K
The human ear is not equally sensitive to all frequencies in the audible range. It may perceive sound waves with the same pressure but different frequencies as having different loudness. Moreover, the perception of sound waves depends on the health of an individual's ears, which decays with age. The health of one's ears may also be affected by regular exposure to loud noises.
The pitch of a sound depends on the frequency and the pressure amplitude of the source. Two sounds of the same...
