Acoustic Attenuation & Cardiovascular Health: Reviewing NIH Environmental Noise Studies

## The Medical Implications of Noise Attenuation The World Health Organization (WHO) and the National Institutes of Health (NIH) recognize environmental noise pollution as a top environmental hazard to public health. Traffic noise, sirens, and aircraft do not merely cause annoyance—they trigger involuntary sympathetic nervous system fight-or-flight reactions. ### Clinical Research Highlights: - **Nocturnal Blood Pressure Spikes:** Even while asleep, sub-conscious auditory processing of traffic noise elevates heart rate and blood pressure by 10%–15%. - **Acoustic Barrier Intervention:** Replacing legacy windows with asymmetric laminated acoustic double glazing (STC 38–42) lowers ambient bedroom noise below 35 dBA. - **Cardiovascular Outcomes:** Long-term longitudinal data demonstrates a significant reduction in hypertension risk among homeowners who installed acoustic replacement windows.
