Effects of Simulated Airplane Cabin Noise on In-Flight Meal Perception in the Brain Using Electroencephalography

Area of Science:

• Neuroscience
• Sensory Science
• Human-Computer Interaction

Background:

• Auditory distractions can negatively affect sensory perception and food evaluation.
• The specific impact of airplane cabin noise on in-flight meal sensory perception is not well understood.

Purpose of the Study:

• To investigate the effects of simulated airplane cabin noise on the visual processing of in-flight meal stimuli.
• To analyze neural responses using electroencephalography (EEG) and event-related potentials (ERPs).

Main Methods:

• Twenty healthy male subjects were exposed to simulated airplane cabin noise and quiet conditions.
• Resting-state EEG and ERPs to visual food stimuli were recorded.
• Analysis focused on brain activity in specific frequency bands and cortical regions.

Main Results:

• Airplane cabin noise increased theta and beta frequency band power in specific brain regions.
• Reduced amplitude of visual meal image responses in the superior parietal area was observed under noise conditions.
• Participants reported discomfort and reduced appetite in the noise condition.

Conclusions:

• Airplane cabin noise disrupts visual perception and attentional processing of in-flight food stimuli.
• Neural changes suggest impaired sensory integration, leading to altered food evaluations during flights.
• Findings highlight the impact of auditory environment on the dining experience.
