The following defined words and/or phrases shall have the meanings set forth herein.
(a) "Weighted sound level" means the sound pressure level in decibels as measured on a sound level meter using the A-weighted network. The level so read is designated as dB(a) or dBA.
(b) "Decibel" means a unit for measuring the volume of sound, equal to twenty times the logarithm to the base ten of the ratio of the pressure of the sound measured to the reference pressure, which is twenty micropascals (twenty micronewtons per square meter).
(c) "Cyclically varying noise" means any sound which varies in sound level such that the same level is obtained repetitively at reasonably uniform intervals of time.
(d) "Demolition" means any dismantling or intentional destruction or removal of structures, utilities, public or private right of way surfaces, or similar property.
(e) "Emergency" means any occurrence or set of circumstances involving actual or imminent physical trauma or property damage or loss which demands immediate action.
(f) "Emergency work" means any work performed for the purpose of preventing or alleviating the physical trauma or property damage threatened or caused by an emergency.
(g) "Impulsive sound" means sound of short duration, usually less than one second, with an abrupt onset and rapid decay.
(h) "Motor vehicle" means every vehicle defined as a motor vehicle in the Ohio Revised Code.
(i) "Motorcycle" means every vehicle defined as a motorcycle in the Ohio Revised Code.
(j) "Motorized bicycle" means every vehicle defined as a motorized bicycle in the Ohio Revised Code. (Ord. 69-91. Passed 7-23-91.)
(k) “Noise" means any sound which annoys or disturbs a reasonable person of ordinary sensibilities, or which causes or tends to cause an adverse psychological or physiological effect on humans, or which exceeds the decibel readings under maximum permissible sound levels as set forth at Section 531.04 of this Code.
(l) "Noise Disturbances" means any sound which:
(1) Endangers or injures the safety or health of humans or animals; or
(2) Annoys or disturbs a reasonable person of ordinary sensibilities; or
(3) Endangers or injures personal or real property; or
(4) Exceeds the decibel readings under maximum permissible sound levels as set forth at Section 531.04 of this Code.
(Ord. 34-21. Passed 7-13-21.)
(m) "Person" means any individual, association, partnership or corporation and includes any officer, employee, department, agency or instrumentality of a state or any political subdivision of a state.
(n) "Place of public entertainment" means any commercial facility open to the general public for purpose of entertainment.
(o) "Powered model vehicle" means any self-propelled airborne, waterborne, or landborne plane, vessel or vehicle, which is not designated to carry persons, including but not limited to, any model airplane, boat, car or rocket.
(p) "Public right of way" means any street, avenue, boulevard, highway, sidewalk, alley or similar place which is owned or controlled by a government entity.
(q) "Pure tone" means any sound which can be distinctly heard as a single pitch or set of single pitches. For the purposes of measurement, a pure tone shall exist of the one-third octave band sound pressure level in the band when the tone exceeds the arithmetic average of the sound pressure levels of the two contiguous one third octave bands by 5dB for frequencies of 500 Hz and above, by 8 dB for frequencies between 160 and 400 Hz and by 15 dB for frequencies less than or equal to 125 Hz.
(r) "Real property boundary" means an imaginary line along the ground surface and its vertical extension, which separates the real property owned by one person from that owned by another person.
(s) "Repetitive impulsive noise" means any noise which is composed of impulsive noises that are repeated at sufficiently slow rates such that a sound level meter set at fast meter characteristic will show changes in sound.
(t) "Sound" means an oscillation in pressure, particle displacement, particle velocity or other physical parameter, in a medium with internal or interval forces that causes compression and rarefaction of that medium, and which propagated as finite speed to distant points. The description of sound may include any characteristic of such sound, including duration, intensity and frequency.
(u) "Sound level" means the weighted sound pressure level obtained by the use of a sound level meter and frequency weighting network, such as A, B or C as specified in American National Standards Institute specifications for sound level meters Publication 51.4-1971, or the latest approved revision thereof. If the frequency weighting employed is not indicated, the A-Weighting shall apply.
(v) "Sound level meter" means an instrument including a microphone, amplifier, RMS detector and integrator, time averager, output meter and/or visual display and weighting networks, that is sensitive to pressure fluctuations. The instrument reads sound pressure level when properly calibrated and is of type two or better as specified in American National Standards Institute Publication 51.4-1971 or the latest approved revision thereof.
