Part 4/7:
Using specialized audio equipment, Paul monitors the vibrational frequencies of the rods. He notes that the aluminum rod resonates at approximately 2,500 Hz to 3,000 Hz, producing a loud sound level measured at around 87 decibels. These measurements are crucial in demonstrating the vibrational characteristics of the material and the effectiveness of his homemade setup.
Demonstrating Resonance: Reproducing Tones
Through a combination of applying touch, vibrational stimuli, and perhaps small adjustments, Paul manages to reproduce specific tones. He demonstrates this by playing music or sounds and then tuning the vibrations on the aluminum rod to match them. This process involves carefully adjusting the point of contact and the applied rosin to optimize resonance.
