Method synopsis

Systematic playback of pre-recorded animal vocalizations from known positions and orientations to validate localization algorithm performance under controlled field conditions.

Synthesized from method descriptions across 2 papers using this protocol.

Procedure from a recent peer-reviewed implementation

Steps below were extracted from the most recent peer-reviewed implementation of this protocol in the corpus — An empirical study of collaborative acoustic source localization (2009), J Sign Process Syst. The protocol was originally introduced by An empirical study of acoustic source localization (2007). Implementations in other papers (listed below) may differ.

1. Conduct controlled playback experiments
   Pre-recorded marmot calls were played back from known positions using a powered speaker (Advent 570 Powered Partner) at distances of 12.5m, 25m, and 50m from the sensor array. Speaker was oriented in three directions: towards the array, perpendicular to the array, and away from the array. Each marmot call was repeated 15 times during each playback experiment.
   Quantities: 3 distances (12.5m, 25m, 50m), 3 orientations, 15 repetitions per call, 135 trials totalDuration: Each call playback not specifiedConditions: Field conditions with natural background noise and reverberation
   Equipment: Advent 570 Powered Partner speaker, pre-recorded marmot calls

Typical Equipment

• Advent 570 Powered Partner speaker
• pre-recorded marmot calls

Output Measurements
