  • Monitoring and recognition of debris flow infrasonic signals
    Based on the above study, a solution can be designed to raise the accuracy of recognizing debris flow infrasonic signals by eliminating false alarm and failure alarm resulted from environmental interference noises.
  • How should the psychological well‐being of zoo elephants be objectively investigated?
    For example, some alarm calls of African elephants are infrasonic [Moussaieff Masson and McCarthy, 1995; O’Connell et al., 2007], and so hard to monitor without specialized equipment.
  • Analysis of the acoustic conversion efficiency for infrasound from atmospheric entry of NEO`s
    By computing this efficiency factor we hope to predict the expected detection rate of large NEO's for the proposed CTBT global scale infrasonic array systems, and to establish the rate of false alarms due to natural atmospheric explosions.
