Introduction
The Health Promotion model was put into test as a causal theory of hearing protection for construction workforce. A study population of 359 characters was selected for the testing of this theory with both exploratory and theoretical models fitting each other well with a variance of 50.6% and 36.3% respectively in hearing protection applicability.
The research identified barriers and values of hearing protection use as the vital forward planners in both the exploratory and theoretical models. In the theoretical model, health status was distinguished to be an individualistic predictor. At times when modifying factors were permitted to directly relate with protection hearing use, two altering aspects erupted as vital predictors. These are interpersonal experiences and exposure to noise (Lusk, 2011).
The research makes an identification of hazardous noise as one of the important health occupational problem because it is detrimental to various physiological effects in addition to hearing loss. This for instance has the possibility to increase stress as one of the common psychological effect of hazardous noise which will contribute to other physiological concerns. A larger population of people estimated at 30 million people is exposed to hazardous noise (McKenna, 2011). Use of hearing protective such as hear muffs and plugs serve to reduce such exposure thus curbing the dangers associated to such noise. However, a larger population of those exposed to this kind of noise proved to minimally use hearing protective devices. A survey carried on the usability of hearing protective devices by factory workforce shows the percentage of user population to be at around 54% to 62%.
The research in its comparison of the hearing protective devices use identifies factory workers to be different from that of construction workforce. The research puts forward the differing factors in the two tested categories of workers exposed to high noise risks (Lusk, 2011). Construction workforce unlike factory workers has little to no control of their working conditions in addition to the dynamism in their working environment that exposes them to a wider variety of noise.
The research employed a random selection of characters for training and testing of the hypothesis of the research. The consideration was the capturing of a wider representation of all the construction professionals and other categories that might be involved in the construction process. The groups were investigated on the length of time exposed to noise and the time that they put on protective devices at the time of exposure (Lusk, 2011). The engineers were the highly exposed but their time length for wearing hearing protective devices based less on the time of exposure to high noise.
A dependable research measurement was utilized with an acceptable degree of precision and reliability scale of 70. The operational definitions and the conceptuality of the model had to be factored into the model testing as a way to satisfy the characteristics of a good theory. A series of questions was used in assessing the exposure to noise. Varied results were obtained with some respondents failing to respond and others failing to finish answering the questions (Lusk, 2011).
The theory was validated after a statistical analysis of the result of the experiment based on the nursing practices (McKenna, 2011). It was thus clear that the usability of hearing protective devices is popular with highly perceived individualistic effectiveness for hearing and lower perception for barrier and health in addition to higher perception for value use. Modifying factors prove to have a different hidden path way for the use of hearing protective devices.
