Hazardous Noises Report After receiving good remarks from your previous work, you hear that Acme Manufacturing Co. has asked you and BSCI to return for some additional work. BSCI has been contracted by Acme Manufacturing Co. to conduct a study to determine employee exposures to noise. In addition, Acme Manufacturing Co. has requested that, while on site, you conduct a needs analysis to determine the development of a new safety training program, exhibiting training and management techniques. Explain your methodology and the steps in conducting this needs analysis. After conducting a field assessment, prepare a written report for Bob Sanders (CSP) to present to the Board of Directors. During your field investigation, you find the following field observations:
Machine Shop #1
The company has an on-site maintenance and repair facility. Inside Machine Shop #1, there are five employees that operate a variety of machines, ranging from stationary and portable grinders, drill presses, and metal shearers. Based on the information provided in the following table, determine the individual employee’s exposure: (DO NOT COMBINE NOISE LEVELS)

Carpentry Shop #2
Inside Carpentry Shop #2, there are six machines operating almost continuously, including table saws, planers, exhaust systems, jointers, with 10 employees working in this area. To determine whether this table should be designated as a hazardous noise environment, thus requiring employees to be entered into the hearing conservation program, you must calculate combined exposures and treat the entire area as one noise source. The following table indicates the recorded measurements that you collected during your on-site assessment. Does the data from this table indicate a hazardous noise environment, and do you recommend entering employees into a hearing conservation program?

Electronic Communication Repair Shop
Acme Manufacturing is currently considering remodeling this shop in order to install a new noise absorbing wall and floor insulation. They have asked that you review the previous history of noise level exposures in this area and provide your recommendations. However, this data is given in measurements of N/m², but the Project Engineer is requesting the information in W/m². Given the following data, convert N/m² to W/m² and include it in your report:

Respond to the details in each section, and format your report in APA style. Include at least each of the following in your report for this unit:
Introduction-briefly describe why the studies were performed (why you started the study).
Report details-briefly discuss the details of the scenario (what you found from the study).
Conclusions and recommendations-briefly describe your recommendations based on your findings (what you recommend to resolve any deficiencies).
Appendix-Measurements and calculations (show your work).
At least one page (double-spaced) in length (not including the reference page and appendices).
