This study proposes a novel coupled acoustic sensor system inspired by the Ormia ochracea fly for improved sound source localization. The system enhances interaural time difference (ITD) cues, significantly reducing localization error compared to traditional methods.

Area of Science:

  • Acoustics
  • Bioacoustics
  • Sensor Systems

Background:

  • Traditional sound source localization methods often rely on interaural time difference (ITD) or interaural intensity difference (IID) cues.
  • Existing ITD-based methods face limitations due to the aperture of the sensor array.
  • The parasitoid fly Ormia ochracea exhibits exceptional sound localization abilities, particularly for cricket calls, despite its small size, due to its coupled ear structure.

Purpose of the Study:

  • To propose a generalized multi-dimensional coupled system with an acoustic sensor array inspired by the Ormia ochracea fly's auditory system.
  • To investigate the use of a magnification factor of the phase difference as a key parameter for measuring coupling effects on ITD.
  • To optimize the coupled system's physical parameters for stable magnification across varying angles of incidence.

Main Methods:

  • Generalizing the structure of the Ormia ochracea fly's coupled ears into a multi-dimensional acoustic sensor array model.
  • Defining and utilizing the magnification factor of the phase difference to quantify the ITD changes within the coupled system.
  • Optimizing system parameters to ensure the magnification factor remains constant regardless of the signal's angle of incidence.
  • Simulating the coupled system's performance and comparing it with the traditional general cross-correlation method.

Main Results:

  • The coupled system demonstrably increases the time delay between received signals.
  • The magnification factor of the phase difference was found to remain stable, independent of the angle of incidence, as per optimization.
  • The proposed coupled system achieved a reduced localization error compared to the traditional general cross-correlation method.

Conclusions:

  • The bio-inspired coupled acoustic sensor system offers a significant improvement in sound source localization accuracy.
  • The system effectively overcomes limitations of traditional ITD-based methods by enhancing and stabilizing ITD cues.
  • This approach holds promise for developing more precise sound localization technologies.
