The highly sensitive seismometer, called the Seismic Experiment for Interior Structure (SEIS), can pick up the most subtle of vibrations, and was provided by the French space agency (CNES), and its partners.
Far below the human range of hearing, these recordings had to be speeded up and slightly processed to be audible through headphones, NASA said on Tuesday.
NASA's InSight lander has something interesting in store again.
Clouds drift over the dome-covered seismometer, known as SEIS, belonging to NASA's InSight lander, on Mars.
Out of more than 100 events detected to date, about 21 are strongly considered to be quakes, NASA said.
NASA's InSight lander placed its seismometer on Mars on December 19, 2018.
The instrument was designed by NASA to listen to the marsquake.More news: Leaders scatter after first French-language debate, hoping to find momentum

Unlike Earth's rambunctious surface (overpowered by the seismic noise of oceans and weather), the Red Planet is extremely quiet, allowis SEIS to pick up even the faintest rumbles from within.
On our planet, the crust is sealed when water fills it with minerals.
According to the researchers, the sounds of the earthquakes indicate that the crust of Mars is "a mixture of" earth and the moon's crust.
"It's been exciting, especially in the beginning, hearing the first vibrations from the lander", said Constantinos Charalambous, an InSight science team member at Imperial College London. Mars' surface is similar to the Moon's and the seismic waves can long for a minute or so.
"You're imagining what's really happening on Mars as InSight sits on the open landscape", he added in a statement. However, on Earth, the quakes only last for seconds. During the day, sunlight warms the air and creates more wind interference than at night.
As the short video plays, not only do you hear what quakes on Mars sound like, you also hear wind gusts, the robotic arm when it moves and shifts positions, and friction from parts within the seismometer. Together, those instruments take measurements of Mars' vital signs, like its pulse, temperature and reflexes - which translate to internal activity like seismology and the planet's wobble as the sun and its moons tug on Mars.
