Field notes
The map divides road and train estimates into three periods: 7 am–7 pm, 7–10 pm, and 10 pm–7 am. Its 24-hour CNEL view also includes an aircraft estimate derived from official airport contours. The homepage cautions that the results are modeled from public data, not measured at the address, and should not be used for legal, medical, or real-estate decisions.
