Specimen.13: Soundscape of the Absolute Vacuum

The Silence of Space and the Score of Terror

Up to the previous chapter, we have traced the trajectories of the bodies and souls of humans (and Synthetics) resisting ruthless corporate systems and monsters of Biomechanics in the harsh environment of space. However, the vast stage that surrounds them—space—is fundamentally an absolute vacuum, a cruel void where even light will eventually die out.

In this endless darkness, the physical phenomenon of “sound” inherently does not exist. As the iconic tagline of this saga states, “In space no one can hear you scream,” the absolute silence in space mercilessly confronts humans with their primal loneliness and powerlessness. The sound design and musical score that run through all seven films of the Alien saga are not mere incidental music meant to stir the audience’s emotions. Rather, they constitute an exquisitely precise “auditory philosophy of life” that contrasts the fragile heartbeat of “humans” as organic matter with the inorganic, violent presence of the “Xenomorph” as the Perfect Organism, alongside the cold laws of the universe.

In this chapter, starting from the mechanical humming within the enclosed space of a spaceship, we will thoroughly dissect the scores and ambient sounds constructed by successive composers from the perspectives of psychoanalysis and Cosmic Horror.

The Construction and Collapse of the “Acoustic Womb” in an Absolute Vacuum

In the vacuum of space dominated by absolute silence, spaceships like the USCSS Nostromo and the Renaissance Station are artificial “wombs” constructed for human survival. In cinematic psychoanalysis, concepts such as the “Acoustic Mirror” proposed by Kaja Silverman and the “Sonorous Envelope” by Didier Anzieu indicate that the sounds of the mother’s heartbeat and blood flow, heard by the fetus through the amniotic fluid in the womb, contribute to a primal sense of security and the formation of the subject.

The ambient sounds inside the spaceships in Alien function precisely as this Sonorous Envelope. What envelops the crew members awakening from the silence of Hypersleep are the rhythmic relay clicks of the artificial intelligence computer known as MU-TH-UR, the flickering sounds of CRT monitors, and the low-frequency mechanical humming emitted by the ship’s hull itself. This sound is the heartbeat of the “maternal body” managed by a ruthless capitalistic corporation, the resonance of artificial amniotic fluid that is supposed to protect the crew. Within this enclosed space, they synchronize their own breathing with the ship’s ambient sounds, enjoying a fleeting sense of safety.

However, with the intrusion of the Xenomorph, this acoustic womb transforms into a locked room of death, and the Sonorous Envelope is torn apart from the inside. The humming within the ship is no longer a sound of protection, but becomes background noise that conceals an invisible predator.

The root of the terror brought by the Xenomorph lies in the fact that it strikes solely as “sound” before its form can be visually perceived. The experience of the “acousmatic” (sound heard without a visible source) in film sound theory functions here as a premonition of absolute death. The faint scratching of claws crawling deep within the ducts, the inorganic fizzing sound of acidic blood melting the metal floor, and the damp, metallic roar echoing from the darkness. These are all cruel signs indicating to the visually deprived humans that an overwhelming predator is right beside them. The absolute deprivation of sight and the situation of being surrounded by sounds of unknown origin fundamentally destroy human reason, dragging the audience down to the dimension of the most powerless “hunted piece of meat.”

Auditory Biomechanics — Jerry Goldsmith’s Primal Acoustic Space

In the first Alien film, composer Jerry Goldsmith achieved the historical feat of translating the “fusion of organic matter and machinery (Biomechanics)” created by H.R. Giger into the auditory dimension. This acoustic approach, which William Whittington named “Audio-biomechanics,” vividly contrasts humanity’s hopeful romanticism with the ruthlessness of the absolute Other.

The theme played by an isolated trumpet in the opening is a warm orchestration that symbolizes the mystery of the vast universe and humanity’s thirst for exploration. However, the moment they land on the unknown planet LV-426 and step into the darkness of the Derelict Ship, the score loses its harmonic structure, plunging the audience into a sea of dissonance and avant-garde textures.

To express the alienness of the Xenomorph, Goldsmith introduced a unique group of instruments powered by raw human breath—such as the didgeridoo, the serpent (a snake-shaped woodwind instrument), and the conch shell—and passed them through a mechanical effect called an Echoplex (a tape delay device). Through this processing, the warm breath of a human is transformed into an inorganic, repetitive mechanical reverberation, manifesting a bizarre acoustic space known as the “Alien Wind.” This is the essence of “Audio-biomechanics,” where the proof of life—breathing—is dismantled and reconstructed by the cold logic of machinery.

Furthermore, the subliminal use of “heartbeat sounds” is particularly noteworthy. When the Xenomorph approaches a human in the darkness, an extremely faint rhythm resembling a heartbeat creeps into the ambient sound. This is not the heartbeat of the cold-blooded Perfect Organism, but rather the sonification of the physiological fear of the human prey, an acoustic trap that forcibly synchronizes with the beating of the audience’s own hearts. The audience unconsciously has their own bodies synchronized, made to realize down to their marrow their powerlessness as mere organisms.

Artificial Heartbeats and the Rhythm of Death — James Horner and the Motion Tracker

In Aliens, James Horner inherited Goldsmith’s avant-garde silence while rewriting it into military panic. While dominated by militaristic rhythms that heavily utilize snare drums and metallic percussion, what truly wears down the audience’s psyche is the inorganic electronic sound of the “Motion Tracker.”

In the terraforming facility shrouded in absolute darkness, the vision of the Marines equipped with state-of-the-art weaponry becomes dysfunctional, and all they can rely on is the green glow of the Motion Tracker and its electronic “beep, beep” sound. This sound functions as an “artificial heartbeat” in the dark, and when the target approaches and the tempo accelerates, it signifies the acceleration of human despair and panic.

Faced with the absolute fact that invisible death is approaching from all directions, the sight of humans—who boast advanced technology—simply cowering and falling into a panic at the high-pitched electronic warnings cruelly depicts the moment human reason collapses before the wildness of the Perfect Organism.

Religious Nihilism and the Elegy of the Flesh — Elliot Goldenthal

In Alien 3, Elliot Goldenthal constructed a religious and liturgical acoustic space on the penal planet Fiorina ‘Fury’ 161.

In the opening track “Agnus Dei” (Lamb of God), a boy soprano sings a Latin hymn solo in an innocent voice amidst chilling dissonance. The contrast between this angelic voice and the metallic, violent percussion symbolizing the tragedy of the Xenomorph elevates the binary opposition of the fragility of the flesh and the violence of the absolute predator into a theological tragedy.

On a planet of prisoners clinging to an eschatological religion, the Xenomorph is given the resonance of an “Angel of Death” purifying sinful humans, and there is absolutely no heroism to be found. And in the finale, during the scene of Ellen Ripley’s messianic sacrifice as she throws herself into the furnace, a tragic theme called “Adagio” resounds, serving as a requiem for her, who defended human dignity to the very end.

The Sensuality of Crossbreeding and the Madness of Creation — From Frizzell to Kurzel

In Alien Resurrection, where Ripley is revived as a clone, John Frizzell inherited the sonic DNA while injecting a heavy, lingering eroticism. By sensually resonating strings while using heavy brass instruments and synthesizers, he brilliantly expresses the “grotesque beauty” of crossbreeding, where the boundary between human and alien has collapsed. Particularly noteworthy is the cry of the Newborn; the resonance, a mixture of a human baby’s cry and a wild beast’s roar, expresses the despair of a life that should never have been born and the poignancy of seeking its mother, filling the screen with the acoustic culmination of bioethics gone wrong.

On the other hand, in Prometheus and Alien: Covenant, it transforms into an orchestration that depicts the “mystery of creation” and its desecration. Jed Kurzel, in particular, quoted Goldsmith’s glorious main theme while dismantling it into an extremely ominous and cold resonance. This musically expresses the process of rebellion against God, where the mad AI David usurps the technology of the Creators to create the Perfect Organism. The soundscape ruthlessly declares that the birth of life is the product of malicious, artificial manipulation.

Analog Fluctuation and the “Violence of Silence” — Return to Romulus

And in the latest installment, Alien: Romulus, Benjamin Wallfisch and the sound team inherited the past mythology while returning the soundscape to its origins. The analog futuristic feel of the 1970s and 80s is meticulously transplanted into the latest spatial audio; system operating sounds and synthetic voices are passed through old tape delay devices, given the “fluctuation” and distortion unique to degraded analog audio. This “fluctuation” acoustically represents the sense of entrapment of the youths exploited by the corporation and the fragility of life in a rusted universe.

Additionally, a noteworthy acoustic direction in this work is the violent use of “absolute silence.” By completely shutting out sound in outer space and zero-gravity states, it forces the audience into a state of extreme tension where they cannot help but be conscious of even their own breathing. When it suddenly shifts from there and the rushing sound of a Facehugger or the roar of the Offspring explosively resounds, silence functions as the ultimate instrument of violence. It expresses the cold truth that silence is the true nature of the universe, and those who make a sound are immediately devoured by the darkness.

A Requiem for Imperfect Humans

The genealogy of the soundscapes running through all seven Alien films is a psychoanalytic clinical record proving how humans are foreign bodies in the universe, imperfect and fragile beings.

The Xenomorph possesses no language and makes no unnecessary sounds to show itself off. For them, as the Perfect Organism, the silence that assimilates with the darkness is the very proof of the perfection of their existence.

On the other hand, imperfect humans tremble in fear, breathe heavily, have their hearts race, and scream. That raw and fragile “sound of life” becomes the fatal signal that summons the malice lurking in the dark. However, as long as that faint rhythm of life continues to resist the silence of the universe and the fear of death, this magnificent symphony of the philosophy of life will continue to resonate eternally in the depths of our unconscious as the audience.

In the next chapter, finally, as the summary of this thesis, we will draw a final conclusion about the true value of life in this universe from the contrast between the “Perfect Organism” and “imperfect humans.”
