Noise Abatement Ordinance
(NAO)

¹ The emis­sions of ex­ter­i­or noise from mo­bile ap­pli­ances and ma­chines must be re­duced to the ex­tent that:

a.

this is tech­nic­ally and op­er­a­tion­ally feas­ible and eco­nom­ic­ally ac­cept­able; and that

b.

the well-be­ing of the af­fected pop­u­la­tion is not ser­i­ously im­paired.

² The en­force­ment au­thor­it­ies shall or­der op­er­a­tion­al and struc­tur­al meas­ures, or those for prop­er main­ten­ance.

³ Where it is not pos­sible to avoid ex­pos­ure to highly dis­turb­ing noise due to the op­er­a­tion of mil­it­ary equip­ment, ma­chines and weapons, the en­force­ment au­thor­it­ies shall re­lax the re­quire­ments.

⁴ The emis­sions of ap­pli­ances and ma­chines that are used to op­er­ate a sta­tion­ary in­stall­a­tion are lim­ited ac­cord­ing to the pro­vi­sions on sta­tion­ary in­stall­a­tions.
