← ScienceWhich acoustic consequence results with prolonged exposure above sound intensity threshold during ultrasonic cleaning?
A)Auditory fatigue from resonating parts
B)Cavitation damage within cleaned objects✓
C)Reduced efficacy due to waveform distortion
D)Harmonic resonance destroying transducers
💡 Explanation
When sound intensity exceeds the threshold, excessive cavitation occur because small bubbles form in the cleaning liquid and violently implode upon the cleaned objects, leading to surface pitting. Therefore cavitation damage is responsible, rather than fatigue, distortion, or resonance needing distinct excitation conditions.
