  1. Douglas W. Hamilton Waste Management Specialist Biosystems and Agricultural Engineering Making Sense of SmellsA Guide for Understanding Farmstead Odors Part 6: Simulated Olfactometry Exercise

  2. How Strong? How Bad? Intensity Offensiveness Odor Measurement

  3. Sniff Test

  4. Sniff Test Intensity Scale = 0 to 6

  5. Sniff Test Intensity Scale = 0 to 6 Offensiveness Scale = 0 to 6

  6. Sample 1 How Strong? _____ How Bad? ______

  7. Intensity Scale 0 = no odor 1 = very faint 2 = faint 3 = distinct 4 = strong 5 = very strong 6 = extremely strong

  8. Offensiveness Scale 0 = Inoffensive 1 = Very faintly Offensive 2 = Faintly Offensive 3 = Definitely Offensive 4 = Strongly Offensive 5 = Very Strongly Offensive 6 = Extremely Offensive

  9. Two Assumptions • Responses are predictable, but show variability within a population

  10. Two Assumptions • Responses are predictable, but show variability within a population • Intensity and Offensiveness are independent measurements
