Listen to the first 760,000 years of the universe

The space observatory Planck physicists from the University of Washington managed to recreate the sounds that accompany the big bang. Physicist John Cramer created the audio, displaying sound frequencies that vary over time. It was discovered in the cosmic microwave background (CMB).

He also created a wider frequency spectrum, where high frequencies are heard. Kramer says that they are added to increase the quality of the audio.

The value of the CMB peaked for 379,000 years and dropped to 60% for 110, 000 years before and after the peak of the emission time. As the universe expands its sound becomes more and more like a bass instrument, because of the expansion of the universe is reduced and sound frequencies.
