The concept of noise sensitivity: implications for noise control

Area of Science:

• Environmental Psychology
• Acoustics
• Health Sciences

Background:

• Noise sensitivity is a widely used term in noise research but lacks a unified definition.
• It encompasses varied effects and measurement methods, impacting health and well-being.
• Individual differences in annoyance from noise sources are central to its concept.

Purpose of the Study:

• To clarify the multifaceted nature of noise sensitivity.
• To differentiate between subjective reports and objective measures of noise sensitivity.
• To inform strategies for noise control by distinguishing sensitive individuals from general population responses.

Main Methods:

• Review of existing literature on noise sensitivity definitions and measurements.
• Analysis of the relationship between noise sensitivity, negative affectivity, and health outcomes.
• Comparison of self-reported noise sensitivity with physiological reactivity and habituation.

Main Results:

• Noise sensitivity is strongly correlated with negative affectivity, questioning the independence of noise-specific measures.
• Physiological reactivity and habituation to noise are often weakly associated with self-reported noise sensitivity.
• Subjective reports and objective indicators of noise sensitivity are influenced by different factors.

Conclusions:

• Distinguishing between subjective and objective aspects of noise sensitivity is crucial.
• Noise control strategies may need to address both general population and highly sensitive individuals.
• Further research should explore the independent effects and distinct influencing factors of noise sensitivity.
