Airport noise impact reduction through operations [PDF]
, 1981 The effects of various aeronautical, operational, and land-use noise impact reduction alternatives are assessed for a major midwestern airport. Specifically, the relative effectiveness of adding sound absorbing material to aircraft engines, imposing ...

Insulating buildings against transportation noise [PDF]
, 2004 Transportation noise contains significant low frequency components. It is difficult to sound insulate buildings against transportation noise because wall cavities are only effective in increasing sound insulation above the mass-air-mass resonance ...

Direct Mode‐Resolved Measurement of Interfacial Phonon Transport by Acoustic Phonon Reflectometry
Advanced Materials Interfaces, EarlyView.We introduce a novel analysis, acoustic phonon reflectometry, that measures the mode‐resolved phonon reflection coefficient at semiconductor interfaces. In aluminum nitride, we observe excellent agreement with the acoustic mismatch model across three distinct interfaces.

Enhanced sound insulation in double wall structures via MAMs: An RBF-based optimisation approach
Materials & DesignDouble walls are widely used as they provide a higher level of sound insulation without compromising on mass. However, due to the coupling resonance between the structure and the cavity, additional sound insulation valleys occur, which are not beneficial
