Words not defined shall be given their common and ordinary meaning, or for those so included, the meaning found in Section 563.01 of the Galion Codified Ordinances.
(a) "A-weighted sound level" means the sound pressure level in decibels as measured on a sound level meter using the A-weighting network. The level so read is designated DBA
(b) "C-weighted sound level" means the sound pressure level in decibels as measured on a sound level meter using the C-weighting network. The level so read is designated DBC.
(c) "Decibel (Db)" means a unit for describing the amplitude of sound, equal to twenty (20) times the logarithm to the base ten (10) of the ratio of the pressure of the sound measured to the reference pressure, which is twenty (20) micronewtons per square meter.
(d) "Sound pressure level" means twenty (20) times the logarithm to the base ten (10) of the ratio of the root mean square (RMS) sound pressure level to the reference of twenty (20) micronewtons per square meter.
(e) “Sound level meter” means an instrument which includes a microphone, amplifier, RMS detector, integrator or time averager, output meter, and weighing networks used to measure sound pressure levels.
(f) "Sound level" means the A-weighted sound pressure level, measured with a sound level meter (SLM).
(g) "Person" means any individual, association, partnership, or corporation, and includes any officer, employee, department, agency or instrumentality of the United States, the State, or any political subdivision thereof.
(h) "Emergency work" means any work performed for the purpose of preventing or alleviating physical trauma or property damage threatened or caused by an existing or imminent peril.
(i) "Noise" means any sound which annoys or disturbs humans or which causes or tends to cause an adverse psychological or physiological effect on humans.
(j) "Sound" means an oscillation in pressure, particle displacement, particle velocity or other physical parameter, in a medium with internal forces. The description of sound may include any characteristic of such sound, including duration, intensity and frequency.
(k) "Property line" means an imaginary line along the surface and its vertical plane extension, which defines the boundary of the real property owned, rented, or leased by the person from that owned, rented or leased by another person. Intra-building real property lines are excluded.
(1) "Average level" means the average of the sound level over some stated period of time.
(m) "Ambient Noise" means the all-encompassing noise that is normally associated with a particular environmental surrounding, usually being made up of a composite of sounds. This is sometimes referred to as background noise.
(n) "Source" means the location of and the activity which emits noise or sound which is audible outside the source owner's property line.
(o) “Receiver” means the location, or land use category of a location, where persons are located who are annoyed by noise or sound they hear coming from another property.
(p) "Holiday Weekend" means the following weekends: New Years Day, Memorial Day, 4th of July, and Labor Day.
(q) "Weekend" means - Friday p.m. - Sunday 10 p.m.
