Noises capable of being so measured, for the purpose of this section, shall be those noises which cause rapid fluctuations of the needle of the sound level meter with a variation of no more than plus or minus two decibels.
(2) 
Noises incapable of being so measured, such as those of an irregular or intermittent nature, shall be controlled so as not to become a nuisance to adjacent uses.
2. 
Smoke.
a. 
No emission of smoke from any source shall be permitted to exceed a greater density than that density described as No. 1 on the Ringlemann Chart;
