When using amplified speakers for classroom demonstrations, start with low volume settings and increase gradually. Prolonged exposure to sound levels above 85 dB can cause hearing damage. Be particularly cautious when switching between different demonstration setups to avoid unexpected loud sounds.

Purpose
