The next circuit in the chain is a high-gain amplifier, so any noise on the supply will then be amplified. Therefore, the Sound Detector may require more careful power supply configuration than many circuits. In testing with various supplies, a significant degree of variability was discovered - some supplies are less noisy than others.
