Data for: Hearable devices with sound bubbles

The human auditory system has a limited ability to perceive distance and
distinguish speakers in crowded settings. A headset technology that can
create a sound bubble in which all speakers within the bubble are audible,
but speakers and noise outside the bubble are suppressed, could augment
human hearing. However, developing such technology is challenging. Here we
report an intelligent headset system capable of creating sound bubbles.
The system is based on real-time neural networks that use acoustic data
from up to six microphones integrated into noise-canceling headsets and
are run on-device, processing 8 ms audio chunks in 6.36 ms on an embedded
central processing unit. Our neural networks can generate sound bubbles
with programmable radii between 1 and 2 meters, and with output signals
that reduce the intensity of sounds outside the bubble by 49 decibels.
With previously unseen environments and wearers, our system can focus on
up to two speakers within the bubble with one to two interfering speakers
and noiseoutside the bubble. It introduces a headset technology that can
create a sound bubble in which all speakers within the bubble are audible,
but speakers and noise outside the bubble are suppressed, which could
augment human hearing. This repo mainly contains the synthetics dataset
for results reported in the paper for 1m, 1.5m, and 2m bubble sizes.
