The "acceptable noise level" will depend on your specific needs! What is "acceptable" in one situation, may be utterly unacceptable in another.

It is assumed that crackers refers to fireworks and not communion wafers. Noise pollution is any unwanted nose or noise which can cause harm to hearing. It may also be defined by loudness, the nature of the noise and other considerations. While fireworks make noise acceptable to the user and his/her audience the noise may be unacceptable to others (shift workers, the ill or those hungover). As such they may be controlled (from a noise point of view) by local ordinances based on factors such as time of day, proximity to other people and the need for a licence or permit. Studies by manufacturers of fireworks have no doubt indicated that consumer satisfaction is tied to the excessive noise produced by their product and research into producing a silent version has been curtailed.

Unacceptable is not an accurate word to define a law. What do you want to mean by unacceptable ?
it is unacceptable
An unacceptable solution is an extraneous one.
"The fistfight at the school board meeting was unacceptable behavior by public officials." "His essay was found to be unacceptable, and he had to rewrite it." "Adding nonsense answers to WikiAnswers is an unacceptable practice."
Well, unacceptable means not acceptable, so you can use it in the sentence,"You only finished half of your homework; this is unacceptable."
Swearing at a teacher is unacceptable.
If the 1999 Suburban noise is a sort of loud banging noise, the problem could be that the engine have jumped time. Jumping time would cause the noise and jerking in the engine.
