• Jaden Pieper and Stephen D. Voran, “Unseen but not Unknown: Using Dataset Concealment to Robustly Evaluate Speech Quality Estimation Models,” Conference Paper, February 2026

  We introduce Dataset Concealment (DSC), a rigorous new procedure for evaluating and interpreting objective speech quality estimation models. DSC quantifies and decomposes the performance gap between research results and real-world application requir...

• Stephen D. Voran and Jaden Pieper, “Frequency-Domain Signal-to-Noise Ratios Illuminate the Effects of the Spectral Consistency Constraint and Griffin-Lim Algorithms,” Conference Paper, October 2025

  The restoration of degraded audio signals is often performed on complex-valued frequency-domain (FD) representations. This requires manipulation of either magnitudes and phases or real and imaginary parts. In general, these manipulations do not prod...

• Nicholas DeMinco, Paul M. McKenna, and Robert Johnk, “A Comparative Analysis of Multiple Knife-Edge Diffraction Methods,” Technical Report NTIA TR 26-580, October 2025

  The results of a thorough comparative analysis of alternative graphical prediction methods for multiple knife-edge diffraction are presented and compared to the method developed by Vogler. The Vogler multiple knife-edge diffraction loss is rigorous ...

• Margaret H. Pinson, Lucjan Janowski, and Mark D. Gross, “Reasons to Replace Term Ecological Validity with Terms Mundane Realism and External Validity,” Conference Paper, October 2025

  The term ecological validity is widely used across IEEE publications, but its definition and application remain inconsistent and ambiguous. This paper explores how conflicting definitions of ecological validity lead to confusion about experimental c...
