← ScienceWhich acoustic outcome occurs when active noise cancellation destructively interferes?
A)Reduced sound wave amplitude✓
B)Increased signal propagation velocity
C)Enhanced harmonic frequency resonance
D)Elevated ambient noise floor level
💡 Explanation
Reduced amplitude is the correct answer, because destructive interference creates antiphase waves that sum to zero or a smaller amplitude; this mechanism relies on superposition of acoustic wave functions. Therefore, quiet results, rather than louder sound, changed speed, or resonance.
