One of the biggest problems for people living in communities of any type – apartment complexes, nearby residential neighborhoods, and so on – is the issue of noise control. This problem arises from several mitigating factors: the quality of building materials for sound insulation, the tolerance levels of individual principles, but above all the behavior of the criminals themselves. In many cases the crime is involuntary because you don't know how well sounds circulate through the walls of your home. On the other hand, a distinct segment of the offending population appears to behave with negligent disregard for the rights of other residents. This is the most serious aspect of noise control and the most difficult to deal with. Often, in group living situations, there is a legal document that binds and mediates the terms of the agreement. A lease or contract usually specifies what residents can and cannot do in their living space; in some circumstances, such as specialist student accommodation, clauses relating to acceptable noise levels set out how and when noise levels will be tolerated. However, many people are not accustomed to carefully reading the terms of such documents, or may not understand them when they do, and violation of such terms is therefore often a matter of ignorance of the provisions of the agreement. This type of transgression is easy to remedy by simply drawing the resident's attention to the terms and indicating that signing the contract constitutes acceptance of the rules. This is more effective if the terms of the punishment are also specified in the document. However, there remain individuals who may or may not be aware of such rules, but adopt an attitude of entitlement regarding their behavior.

Furthermore, as marginal as it may seem, environmental stresses such as water leaks, air pollution in urban areas or malfunctioning climate control add to overall stress levels; Residents suffering from external stressors are often less generous with their neighbors' otherwise tolerable noise levels. Just as external stressors can increase the level of irritation created by excessive sound, reckless noise can create stress and general discomfort among people living in confined spaces. Although it may seem trivial for those who have never had to deal with annoying noises in their homes, solving this problem contributes to the general well-being and harmony of group living situations..
