§ 14-30. Measurement techniques.

(a)

Except for noise within multifamily or multi-tenanted structures, noise measurements shall be made ten feet away from the boundary line at the point where the highest noise levels appear to be; but when the measurements in these locations are not practical, noise measurements may be made at the boundary of the public right-of-way which adjoins the complaining property. Such noise measurements shall be made at a height of at least four feet above the ground and at a point approximately ten feet away from walls, barriers, obstructions (trees, bushes, etc.) on a sound level meter operated on the "A" weighting network (scale). In the case of noises within multifamily or multi-tenanted structures, noise measurements shall be made in the complaining unit at a height of at least four feet above the floor and at a point approximately equidistance from all walls on a sound level meter operated on the "A" weighting network (scale).

(b)

No individual other than the operators shall be within ten feet of the sound level meter during the sample period.

(c)

Sound measurements shall be conducted at that time of day or night when the suspect noise source is emitting sound.

(d)

The sound level measurement shall be determined as follows:

(1)

Set the sound level meter on the "A" weighted network.

(2)

The operator of the sound level meter shall face the noise source and record the meter's instantaneous response (reading) observed at consecutive ten-second intervals until 100 readings are obtained.

(e)

It shall be unlawful for any person to interfere, through the use of sound or otherwise, with the taking of sound level measurements.

(f)

If the operator uses an integrating sound level meter for at least ten minutes, in accordance with its specifications, the results shall also be admissible.
