Full Breakdown

Beaverton City Code Chapter 5.15 (the noise ordinance) reaches bass-heavy sound through BC 5.15.030(L): a radio, television, boombox, stereo, musical instrument, or similar device that is plainly audible beyond its operator and voluntary listeners, and that unreasonably disturbs residents or carries 50 feet into a commercial or public space, is a per se violation. There is no separate low-frequency or vibration standard, bass complaints fall under this general test, plus the nighttime factor in BC 5.15.025(B)(7): sound exceeding 50 dBA at a noise-sensitive property line between 10 p.m. and 7 a.m. Applies inside the city limits of Beaverton, Washington County, Oregon.

Violations & Fines

Violating BC 5.15.030 is a Class I civil infraction under BC 5.15.040, enforced by Beaverton Police; a municipal judge may fine repeat violators within 24 months up to $1,000.
