High channel count microphone array accurately and precisely localizes ultrasonic signals from freely-moving mice.

ABSTRACT:

Background

An integral component in the assessment of vocal behavior in groups of freely interacting animals is the ability to determine which animal is producing each vocal signal. This process is facilitated by using microphone arrays with multiple channels.

New method and comparison with existing methods

Here, we made important refinements to a state-of-the-art microphone array based system used to localize vocal signals produced by freely interacting laboratory mice. Key changes to the system included increasing the number of microphones as well as refining the methodology for localizing and assigning vocal signals to individual mice.

Results

We systematically demonstrate that the improvements in the methodology for localizing mouse vocal signals led to an increas
