DoubleEcho: Mitigating Context-Manipulation Attacks in Copresence Verification
, 2019 Copresence verification based on context can improve usability and strengthen security of many authentication and access control systems. By sensing and comparing their surroundings, two or more devices can tell whether they are copresent and use this ...

Reverberation Time Measurements in the NASA Langley Exterior Effects Room (EER) [PDF]
One-third octave band background noise and reverberation time measurements were conducted in the Exterior Effect Room (EER) at the NASA Langley Research Center. The related overall acoustic absorption of the room was calculated. The acoustic field in the

Comments on “Reverberation Radius in Real Rooms” [PDF]
Telfor Journal, 2012 The goal of this letter is to comment on the article "Reverberation Radius in Real Rooms" by Mijić and Mašović (2010). Mijić and Mašović measured critical distance and reverberation time in four different size rooms from 125 Hz to 4 kHz octave bands ...

Room response to frequency change and its relation to the pitch changes
Archives of Acoustics, 2014 When a signal of constant frequency is sent into a room and its frequency changes to a new value, then, beginning from this moment, in the room there will exist two signals with changing amplitudes (i.e. decreasing one with the old frequency value and an

Effects of Fiber Denier, Fiber Cross-Sectional Shape and Fabric Density on Acoustical Behavior of Vertically Lapped Nonwoven Fabrics [PDF]
Journal of Engineered Fibers and Fabrics, 2008 Acoustical insulation and absorption properties of nonwoven fabrics depend on fiber geometry and fiber arrangement within the fabric structure. The different structures of the fibers result in different total surface areas of nonwoven fabrics.
