About Cosmic Sounds
The universe is filled with vibrations and electromagnetic waves that, when translated into audible frequencies, reveal the hidden symphony of the cosmos.
These sounds are based on actual astronomical data, including radio telescope observations and spacecraft measurements, converted into frequencies humans can hear.
