Population	Exposure	Comparator	Outcomes
General population, including persons participating in laboratory studies of noise exposure	Incremental increase in noise exposure as measured in dBA noise metrics	Noise exposure (i.e., sound pressure level) as measured in dBA. Noise exposure can come from aircraft, road traffic, rail, wind turbine, or industrial/occupational noise exposure	Blood pressure, hypertension, heart rate, cardiac arrhythmia, vascular resistance, and cardiac output
