Challenges

The main acoustical challenge on this project was mechanical noise. The roof of the hospital contains three loud chillers, various other mechanical equipment, and a helipad. In addition to considering the noise disruption to the patients in the rooms on the top floor, our team thought about the patients exiting the helicopter who had to pass by the loud machinery to enter the hospital, as well as the noise to the neighborhood surrounding the hospital.

Solutions

After taking all these acoustical factors into consideration and doing calculations to get a sense of the effects of the noise, we presented our findings to the clients and helped them make the best decision for their building. Ultimately, the owners decided to purchase quieter chillers to minimize the noise to the patients and the neighborhood. This is truly designing with community in mind. Our team put themselves in the place of a child patient in a top floor hospital room and a homeowner living down the street from the facility to come up with the perfect solution that balanced everyone’s needs and factored in everyone’s comfort.
