What will the program achieve?
Research Goal 3.3 - Reduce noise exposures to construction workers using a web-based database for powered hand tools
The following related research and development effort is currently being conducted by the HLR program. Outputs, transfers, and outcomes are expected in the near future.
Reducing Noise on Power Hand Tools
The HLR program is taking the lead in establishing a consortium of powered hand tool manufacturers, noise control experts, government agencies (OSHA and EPA), labor organizations, and insurance carriers to identify and solve noise emission concerns on the over 3500 tools on the market. This team approach is an efficient use of available resources and will enhance the likelihood of reducing noise emissions from these tools.
Encourage Engineering Students to Become Noise Control Professionals
Acoustical engineers are not in abundance either in the general workforce or on college campuses, so it is important to occupationally-related hearing loss prevention efforts to promote the development of noise control expertise in both industry and academic environments. An opportunity to do so seemed to arise with the effort to create a Web site about noise from power hand-tools used in the construction industry (see preceeding section). For the past two years, the “student paper of the year” at the annual Institute for Noise Control Engineers(INCE) conferences has been awarded to a student researcher involved in these powered hand tool projects., As a result of the partnership at the University of Cincinnati, acoustics class enrollment showed stronger student interest. Enrollment before the partnership was 10-15 students. Now, four years later, enrollment is 25-30. The course professor said, “More students are signing up for the class as a result of touring the lab facility, talking to students involved in the partnership in previous years, and being provided the opportunity to apply their newly learned engineering noise control skills to solve real world problems.” The potential impact of this effort will hopefully be seen in an increase in the number of graduating students with noise control expertise who will be entering the workforce in the near future.
