Capstone Experience Proposal
The focus of this project is to do an evaluation of the preliminary results observed in the first two years of the study. I am interested in answering the following questions:

Baseline Assessments (Year 1 Data)
1. How do noise exposures among participating farmers (both control and intervention farmers) compare to the Occupational Safety and Health Administration Permissible Exposure Limit (OSHA PEL), the National Institute for Occupational Safety and Health Recommended Exposure Limit (NIOSH REL), and the American Conference of Governmental Industrial Hygienists Threshold Limit Value (ACGIH TLV) for noise?
2. How severe is hearing loss among this group of participating farmers (both control and intervention farmers)?
3. Does one ear tend to have more hearing loss than the other ear, or is hearing loss evenly distributed between ears?
4. Do any farmers among this group of participating farmers (both control and intervention farmers) have any notches in their current hearing profile (a notch is defined as ‘the frequency where the hearing level is preceded by an improvement of at least 10 dB at the previous test frequency and followed by an improvement of at least 5 dB at the next’?
a. If so, at which frequencies are notches typically observed?
5. What are the general attitudes and beliefs regarding hearing protection and hearing loss among this group of participating farmers (both control and intervention farmers)?
