Sec. 26-52. Definitions.
The following terms, when used in this article, shall have the meanings hereinafter ascribed to them, unless otherwise clearly indicated by the context:
(a) A-weighted sound level. The sound pressure level in decibels as measured on a type II sound level meter as specified in the American National Standards Institute for sound level meters (S1.4-1983 or a later revision thereof) using the A-weighing network. The sound level so read is designated dB(A).
(b) Business commercial area. As defined in the Zoning Ordinance of the City of Lynchburg, 1979 (hereinafter "Zoning Ordinance").
(c) Decibel (dB). A unit for measuring the volume of sound, equal to 20 times the logarithm to the base ten of the ratio of the pressure of the sound measured to the reference pressure, which is 20 micropascals (20 micronewtons per square meter).
(d) Emergency. Any occurrence or set of circumstances involving actual or imminent physical trauma or property damage which demands immediate action.
(e) Emergency work. Any work performed for the purpose of preventing or alleviating the physical trauma or property damage threatened or caused by an emergency.
(f) Industrial area. As defined by the Zoning Ordinance.
(g) Motor vehicle. Every vehicle defined as a motor vehicle by Section 46.2-100, of the Code of Virginia, 1950, as amended.
(h) Noise. Any sound which annoys or disturbs humans or which causes or tends to cause an adverse effect on humans.
(i) Noise disturbance. Any sound which (i) endangers or injures the safety or health of humans or animals; or (ii) annoys or disturbs a reasonable person of normal sensitivities; or (iii) endangers or injures personal or real property.
(j) Person. Means any individual, corporation, cooperative, partnership, firm, association, trust, estate, private institution, group, agency, or any legal successors, representative, agent or agency thereof.

(l) Residential area. As defined in the Zoning Ordinance.
(m) Sound. An oscillation in pressure, particle displacement, particle velocity or other physical parameter, in a medium with internal forces that causes compression and rarefaction of that medium. The description of sound may include any characteristic of such sound, including duration, intensity and frequency.
(n) Sound level. The weighted sound pressure level obtained by the use of a type II sound level meter as specified in the American National Standards Institute specifications for sound level meters (S1.4-1983 or a later revision thereof).
(o) Sound level meter. A type II sound level meter as specified in the American National Standards Institute specifications (S1.4-1983 or later revision thereof) and used to measure sound pressure levels. (Ord. No. O-91-170, 7-9-91, eff. 9-1-91.)
