Definition: This category differs from others in that it includes disorders identifiable on the basis of not only symptoms and course but also the existence of one or other of two causative influences: an exceptionally stressful life event producing an acute stress reaction, or a significant life change leading to continued unpleasant circumstances that result in an adjustment disorder. Although less severe psychosocial stress ( life events ) may precipitate the onset or contribute to the presentation of a very wide range of disorders classified elsewhere in this chapter, its etiological importance is not always clear and in each case will be found to depend on individual, often idiosyncratic, vulnerability, i.e. the life events are neither ...[+++] necessary nor sufficient to explain the occurrence and form of the disorder. In contrast, the disorders brought together here are thought to arise always as a direct consequence of acute severe stress or continued trauma. The stressful events or the continuing unpleasant circumstances are the primary and overriding causal factor and the disorder would not have occurred without their impact. The disorders in this section can thus be regarded as maladaptive responses to severe or continued stress, in that they interfere with successful coping mechanisms and therefore lead to problems of social functioning.

In the case of noise pollution, however, no change to the current limit values is proposed, since noise emissions relate not only to engine noise, but also to external environmental conditions: these two factors make it very difficult to amend the existing rules.

(2) Crew accommodation must meet the requirements and the related provisions on health and safety protection and accident prevention, with respect to preventing the risk of exposure to hazardous levels of noise and vibration and other ambient factors and chemicals on board vessels, and provide an acceptable occupational and on-board living environment for employees.

Transport Canada and other responsible third parties have three principal noise reduction strategies: reducing the noise at the source, managing land use in the vicinity of airports, and managing operational procedures.

Mr. Darrell Campbell: It's like Sid stated earlier—I don't know if you heard Sid or not—until you start dealing with the noise factors and all that is tied in with it, i.e. even for an hydraulic hose to break, because they're turbined by the hydraulics.There's a bunch of issues we have to look at.
