The Illusion of Generalization: Impact of Ultra-Low Synthetic Contamination on Deep Waveform AI Scratch Training in Acoustic Leak Detection

This paper investigates the fundamental problem of false adaptation in deep neural networks applied to non-destructive testing (NDT) of pipelines. Under severe field data shortages, developers often rely on surrogate audio files generated by rapid, heuristic methods (such as LLM-...
