Now you know where to go to find some peace and quiet.
The areas are charted according to A-weighted decibels, also called dB(A), which is the expression of the relative loudness of sounds in air as perceived by the human ear.
The loudest areas clocking in at 60 or more dB(A) are the neighborhoods bordering 280 and 101 (not a surprise), but also the Fillmore District and a tiny pocket between Lower Haight and Hayes Valley.
I can deduce that the noise would be high in the Lower Haight/Hayes Valley section due to the 101 exit, but I am unsure why that one patch of the Fillmore District is so high – if you have any idea, please do share.
Treasure Island and Yerba Buena Island are also one big blue blob of noisiness, which is curious. Yes, there is the bridge and Interstate 80, but I’ve always found it to be super quiet there.
The still-loud-but-not-as-loud areas at 50-60 dB(A) are predominantly SoMa, Mission Bay, Japantown, Western Addition, Civic Center, Lower Haight, and parts of the Marina/Russian Hill.
These areas bleed into the moderately loud areas that range from 40-50 dB(A): more SoMa, Russian Hill, the Marina, the Tenderloin, the Mission, the Castro, Duboce Triangle, Haight-Ashbury, Anza Vista, Cole Valley, Saint Francis Wood, Diamond Heights, Westwood Park, Potrero Hill and the Dogpatch, as well as more peripheral neighborhoods like Visitacion Valley and Crocker-Amazon. So basically everywhere.
As far as the rest of the city goes, the majority blends into the 20-40 dB(A) range, getting quieter as you go west.
Looking for your little patch of zen? Head to the Outer Richmond, Outer Sunset, or the waterfront outskirts between the Dogpatch and Bayview—however, I personally think you’ll find more peace and a prettier view on the Ocean Beach side of the city.
