Decibel-based de facto GLB constraint via Town Code Chapter 144 (Unreasonable Noise). Two enforceable mechanisms across a property boundary: (1) §144-3M explicitly names "lawn or garden tool" — operation that creates an unreasonable noise across a property line is restricted to weekdays 7 a.m. – 9 p.m. and weekends 8 a.m. – 9 p.m. (amended 2017-06-20 by L.L. No. 52-2017); (2) §144-5 imposes octave-band decibel ceilings on any "mechanism or device which shall create a noise within the Town of Hempstead" — Table II (steady-state, all hours) caps at 72 dB at 63 Hz declining to 32 dB at 8000 Hz, and Table I (transient) caps at 92 dB / 52 dB across the same band with a 12-second daytime / 6-second nighttime duration trigger. Typical GLB output of 85–100+ dB(A) for sustained periods exceeds §144-5 Table II across most of the audible spectrum, providing a credible enforcement hook against routine GLB use across a property line even though Chapter 144 contains no fuel-source-specific language. NO formal fuel-source distinction.
