Our Sun is an extremely loud star but the space vacuum prevents its sound from reaching us. If space Vacuum were replaced with air the Sun would be incredibly noisy to our ears. So loud that you would struggle to hear anything else. We would hear the sun burning at over 100 decibels like a rock concert at all hours of the day or as loud as a chainsaw from 5 meters away.
That’s during the day, night would be different as we turn away from the sun, the roar would fade and we might even be able to hold conversations. But that raises a question of the hearing itself if humans had evolved in a loud and roaring sound of Sun. We likely wouldn’t have the hearing abilities as hearing would mean a painful sound all the time.
