Acoustic Health Rating
The Acoustic Health Rating is the fourth pillar of Longevity by Design. It keeps continuous sound exposure below the WHO threshold of 55 dB through acoustic treatment, room geometry and HVAC specification. Noise is treated not as a comfort preference but as a physiological stressor with documented cardiovascular consequences.
WHO Europe data links continuous noise above 65 dB to an approximately 20% increase in cardiovascular disease risk. Chronic noise elevates stress hormones and disrupts sleep architecture even when the sleeper does not consciously wake. Designing below the 55 dB line removes a constant, invisible load on the heart and nervous system.
Frequently asked
What is the Acoustic Health Rating?
It is the acoustic pillar of the Longevity by Design methodology — a specification that keeps continuous indoor sound exposure below the WHO 55 dB cardiovascular threshold.
Can noise really affect lifespan?
Yes — WHO Europe links continuous noise above 65 dB to roughly a 20% higher cardiovascular disease risk. Keeping exposure below 55 dB reduces that constant physiological load.
