Summary
Beyond the specific noises Chapter 35 already bans, the Town of Islip enforces a general ceiling: no source of sound, on any category of property or public right-of-way, may exceed the A-weighted decibel limits Noise Control Table 1 sets for that property type, measured at the boundary of the property receiving the sound, under § 35-4(A).

In addition to the prohibited noises enumerated in § 35-3 of the within chapter, for which no measurement of sound is required, no person shall cause, suffer, allow or permit the operation of any source of sound on a particular category of property or any public lands or right-of-way in such a manner so as to create a sound level that exceeds the particular sound level limits set forth in Table 1, when measured at or within the real property boundary line of the receiving property.
