Audio monitoring system for assessing wildlife biodiversity
First Claim
Patent Images
1. A method for assessing biodiversity in an environment, said method comprising the steps of:
- obtaining vocalizations from a plurality of locations in the environment;
deriving auditory data from the vocalizations for each of said locations;
recording the auditory data in digital format;
processing the recorded data for each of said locations;
identifying predetermined characteristics of the processed data to identify the wildlife species from which the vocalizations are derived for each of said locations;
quantifying the wildlife species identified at each of said locations; and
assessing the biodiversity of the environment on the basis of the number of wildlife species identified.

Abstract
The invention relates to an automated system for monitoring wildlife auditory data and recording same for subsequent analysis and identification. The system comprises one or more microphones coupled to a recording apparatus for recording wildlife vocalizations in digital format. The resultant recorded data is preprocessed, segmented, and analyzed by means of a neural network to identify the respective species. The system minimizes the need for human intervention and subjective interpretation of the recorded sounds.
