Benchmark Datasets for Sound Source Localization

A dataset of sounds emitted by a stationary speaker at ~400 positions.

Stimuli include 5 noise-free gerbil vocalizations and a white noise stimulus, each presented at three volume levels.

The speaker's positions lie along a square grid with ~2cm spacing.

A dataset of sounds emitted by an Edison robot performing a random walk around Environment 1. The stimuli are gathered from longitudinal recordings of gerbil families [Peterson et al. 2023. eLife] and presented through an earbud. The dataset includes ground truth locations for the earbud and the robot’s orientation.

A dataset of sounds emitted by an earbud affixed to the head of a freely-behaving adult gerbil. The stimuli are gathered from longitudinal recordings of gerbil families [Peterson et al. 2023. eLife].

A dataset of sounds emitted by an ultrasonic speaker affixed to a Freenove hexapod robot walking in parallel lines across Environment 2. As it walks, the arm carrying the speaker is rotated to different orientations to vary the directionality of the emitted sounds throughout the dataset. The stimuli are gathered from longitudinal recordings of gerbil families [Peterson et al. 2023. eLife].
