    en.wikipedia.org/wiki/Sound_Suppression_System

    Sites for launching large rockets are often equipped with a sound suppression system to absorb or deflect acoustic energy generated during a rocket launch. As engine exhaust gasses exceed the speed of sound , they collide with the ambient air and shockwaves are created, with noise levels approaching 200 db.

  4. Cosmic noise - Wikipedia

    en.wikipedia.org/wiki/Cosmic_noise

    Cosmic noise, also known as galactic radio noise, is a physical phenomenon derived from outside of the Earth's atmosphere. It is not actually sound, and it can be detected through a radio receiver , which is an electronic device that receives radio waves and converts the information given by them to an audible form.

    Explorer 50 also called IMP 8 (Interplanetary Monitoring Platform 8) in Orbit. Explorer 50 was a drum-shaped spacecraft, 135.6 cm (53.4 in) across and 157.4 cm (62.0 in) height, with propulsion Star-17A, instrumented for interplanetary medium and magnetotail studies of cosmic rays, energetic solar particles, plasma, and electric and magnetic fields.

    The ambient noise should thus increase in the daytime while reducing at night. Apart from the temporal variation, the spatial variation can also matter. For example, the commercial shipping is usually concentrated on certain routes. The corresponding amplitude of ambient noise should also decrease when moving away from the shipping routes. [13]
