All terminology used in this chapter shall be in conformance with applicable publications of the
American National Standard Institute(ANSI) or its successor body.
Ordinance No.2017-d4
Page 2
4-4-2: WEIGHTED SOUND LEVEL:
Sound level meter meeting Class 1 or Class 2 requirements as defined by IEC 61672 or ANSI
S 1.4 and which is specified by the meter manufacturer to have a Measurement Level Range that
encompasses the noise level to be measured. When the sound level measurement is to be made
indoors, a Class 1 meter may be required to check for conformance with the sound level limits
because most Class 2 meters to not have a Measurement Level Range that extends low enough.
4-4-3: SOUND LEVEL METER SETTINGS
A. Sound level meter shall be set to A-weighting(frequency weighting).
B. Sound level meter shall be set to Slow meter response(1-second exponential time averaging).
C. Measured sound level shall be the maximum("x) sound level, attributable to the source
under investigation, which is measured during the measurement period.
4-44: MEASUREMENT LOCATION:
A. Measurement may be made anywhere within the receiving property,but must be made at
least 3 feet from any building fagade or other surface.
B. Measurement may be made at any height above grade, at or near locations that are regularly
occupied by people. For example, a measurement may be made at a position 3 feet to the
exterior of a 2nd floor window since people can be expected to occupy the 2nd floor room.
C. Measurement may be made inside a structure on the receiving property, in any space that is
classified as inhabitable and constructed with necessary City construction permits.
D. If measurement is to be made within a building on the receiving property, then measurement
shall be made with windows, doors, and other openings to the exterior closed and
measurement shall be made at least 3 feet from floor, ceiling, and all other partitions or
surfaces.
E. If the sound source is in a Public Park or Other Public Open Space and sound level
measurement is to be in the Public Park or Other Public Open Space then the measurement
location shall be no closer than 50 feet from the source.
4-4-5: HOURS AND LEVELS:

Limit
1. DURATION of noise in any one-hour period(use one adjustment
only):
a. 12 minutes and longer Add 0 dBA
b. Under 12 minutes but over 3 minutes Add 5 dBA
c. Under 3 minutes but over %minute Add 10 dBA
d. Under %minute Add 15 dBA
2. Noise is IMPULSIVE in character(e.g. hammering, firearms Subtract 5 dBA
discharge, explosions)
3. Content of noise includes electronically amplified,reinforced, or Subtract 5 dBA
reproduced voice or music
4. Noise is TONAL in character(e.g. hum, screech) Subtract 10 dBA
5. If measured within a building on the receiving property per Subtract 20 dBA
Paragraph 4-4-4.0 and 4-4-4.D
B. All Table 2 adjustments which are relevant to the noise shall be applied. For example, if
the noise source is tonal and has a duration of less than 12 minutes in any one hour period
then the Sound Level Limit shall be increased by 5 dBA for the Duration adjustment and
decreased by 10 dBA for the Tonal adjustment.
4-4-6: EXEMPTIONS:
A. Emergency Operations: Emergency short term operations which are necessary to protect the
health and welfare of the citizens, such as, emergency utility and street repair, fallen tree
removal or emergency fuel oil delivery shall be exempt,provided that reasonable steps shall

Particle velocity as specified in Table 1 may be measured directly, or if computed on the basis of
displacement and frequency,measurements shall be computed from the formula 6.28 FD, where
F is the frequency of the vibration in cycles per second and D is the single amplitude
displacement of the vibration in inches.
The maximum particle velocity shall be the vector sum of three(3) simultaneous mutually
perpendicular components recorded.
For the purpose of this title, steady state vibrations are vibrations which are continuous, or
vibrations in discrete impulses more frequent than one hundred(100)per minute. Discrete
impulses which do not exceed one hundred (100)per minute shall be considered impact
vibrations."
Section 4: This Ordinance shall be in full force and effect upon its passage, approval, and
publication as provided by law.
