Preston is interested in the impact of noise on excitability levels in teenagers. He exposes one third of his participants to music at 100 decibels (the maximum volume on many mp3 players), one third of his participants to music at 50 dB (normal conversational level), and one third of his participants to a quiet room with no sounds (0 dB). After exposing them to the noise condition for 10 minutes, he immediately measures their excitability by measuring their heart rate. What is an issue that the IRB might have with Preston's study?
