Summary

The purpose of the study, Effects of Interaction of Caffeine and Hydration on Voice Performance, is to gather information about the effects of caffeine and hydration upon voice performance. The research question involves whether systemic hydration may reduce degradation on voice performance caused by caffeine ingestion. It is hypothesized that the hydration conditions will result in a less degraded vocal performance as compared with the nonhydration condition.The investigation involves abstention from any caffeine ingestion for 24 hours - from 8pm the day before testing to 8am the morning of testing. In addition, preparation for participation involves abstaining from ingesting any foods and liquids for 12 hours - from 8pm to 8am of the following morning. Each test will take about 10 minutes.
