Full Breakdown
Rialto uses a plainly-audible test rather than decibel meters: an officer only needs to detect the sound with unaided hearing, and feeling the rhythmic bass of music is enough (Section 9.50.020 definition). Section 9.50.030(A)(4) prohibits personal or commercial music equipment plainly audible across property boundaries, through partitions between residences, at 50 feet between 8:00 a.m. and 10:00 p.m., or at 25 feet between 10:00 p.m. and 8:00 a.m. Officers first issue a written abatement notice; a second violation within 72 hours allows confiscation and impoundment of the amplifying components (Sections 9.50.030(D)-(E)). City-authorized outdoor gatherings, dances, shows, and entertainment events are exempt under Section 9.50.060.
