As a game music and sound designer, I feel that the sound processing of the film is already in place. Tearing radio sounds, hollow space cabin sounds, etc. The processing of these sounds has basically replaced the original music.
Of course from a scientific point of view. It should be considered common sense that the internal communication sound recorded while wearing a helmet should not change in reverberation as it enters the cabin from space. However, in order to highlight the small metal claustrophobic space in the Soviet space capsule, the sound was deliberately handled as described above. As an audition effect. It is indeed remarkable. But this is also the best example of sober all the students who are immersed in the real events of this film.
