NASA’s Voyager 1 spacecraft recorded the sounds using an onboard plasma wave instrument. This instrument detected the vibrations of dense interstellar plasma, or ionised gas, from October to November 2012 and April to May 2013. The waves detected by the instrument antennae can be simply amplified and played through a speaker. These frequencies are within the range heard by human ears.
