You work part-time at a 3D printing facility on campus and the facility manager has complained about the noise level. The room measures 55 ft by 120 ft, and the ceiling is unpainted, smooth concrete. You have assessed the noise level of this room to be 75 dB. You work with a capstone team who assess two ways to reduce noise. First, if you install noise absorbing mats, you will reduce the noise sound pressures (in dynes) by 60%. Second, if you use professional noise-cancelling earmuffs for everyone in the facility (63 people currently have access), you will reduce the noise sound pressures (in dynes) by 90%. a. What would be the predicted noise level in dB for both methods and which option you would suggest? b. What are some other considerations in addition to the level of dB reduction and cost that may affect the successful implementation of your recommendation
