AeroAcoustic-2026-04-18 Executive Summary This report provides a detailed examination of Jet Audio Skins (JAS) — a class of adaptive acoustic metamaterials designed to mitigate jet engine noise at its source and along fuselage boundary layers. As aircraft noise regulations tighten (e.g., ICAO Chapter 14) and urban air mobility expands, JAS technology promises a paradigm shift from passive sound-absorbing liners to intelligent, frequency-selective, structurally integrated skins. jet audio skins

Key findings indicate that current prototypes of Jet Audio Skins can achieve up to 8–12 dB additional noise suppression in the 500 Hz–5 kHz range compared to traditional honeycomb acoustic liners, while adding less than 1.5% to engine nacelle mass. However, challenges remain in thermal stability (exceeding 300°C near the nozzle exit) and erosion resistance at high Mach numbers.
