Which risk increases when an underwater acoustic transducer array operates near a resonant frequency?

💡 Explanation

Self-interference rises because constructive and destructive interference from element spacing amplifies at resonance, resulting in wave propagation anomalies that reduce array gain; therefore, self-interference increases, rather than refraction errors or exceeding electrical ratings.
