• In some forests of central Africa, the Amazon and Borneo, the sounds of chainsaws and gunshots — signs of illegal activities such as logging and poaching — are picked up and communicated to forest managers by unlikely tools: acoustic devices.
  • While bioacoustics (the study of the study of animal sound production, dispersion and reception) is being used worldwide to not only monitor threats to biodiversity but also study animal behaviour and diversity, the field is still in its nascent stages in India.

Bioacoustic Sensing (Concept Builder)

  • Bioacoustic Sensing combines sensing technology, machine learning, biology and acoustics.
  • This involves neurophysiological and anatomical basis of sound production and detection, and relation of acoustic signals to the medium they disperse through.
  • Bioacoustics uses digital technology, including equipment and software, to record and analyze the sounds.
  • Listening is one of the main methods used in bioacoustical research.
  • Animal behaviour and the signals themselves are used for gaining insight into the production, detection and interpretation of sounds in animals.
  • Bioacoustics Sensing has been used to locate, identify animals and their condition, used in humans for medical applications, such as measuring body sounds on skin surface.
  • It is also used in wearable consumer electronics with mobile phones, laptops and electronic appliances.
  • In healthcare, the medical applications include monitoring  and evaluation of vitals.
  • Skinput is a technology that appropriates the human body for acoustic transmission
  • SixthSense is a wearable gestural interface that augments the physical world around us with digital information.
