My interest in the militarisation of vision is longstanding, but it’s important not to exaggerate the salience of an increasingly ‘optical war’.  Through ‘The natures of war’ project (see DOWNLOADS tab) I’ve also been drawn to the importance of sound in conducting, surviving and even accounting for military violence (see, for example, here, here, and here).  And, as Martin Daughtry‘s remarkable Listening to war (2015) shows, sound continues to be significant in later modern war too.

Even its absence is significant, sometimes performative: think of all those video feeds from Predators and Reapers that, as Nasser Hussain so brilliantly reminded us, are silent movies – apart from the remote commentary from pilots and sensor operators:

‘The lack of synchronic sound renders it a ghostly world in which the figures seem unalive, even before they are killed. The gaze hovers above in silence. The detachment that critics of drone operations worry about comes partially from the silence of the footage.

The contemporary militarisation (or weaponisation) of sound is double-edged, and I mean that in several sense.

First, Mary Roach has a revealing chapter in Grunt: the curious science of humans at war (2016) on what she calls ‘Fighting by ear: the conundrum of noise’.  It turns out that 50 – 60 per cent of situational awareness comes from hearing – and yet the sound of war can be literally deafening.  The damage is often permanent, but in the heat of battle hearing loss makes it difficult to parse the torrent of noise – to distinguish offensive and defensive fires, to detect direction and range, and to send and receive vital communications.  Mary explains:

For decades, earplugs and other passive hearing protection have been the main ammunition of military hearing conservation programs. There are those who would like this to change, who believe that the cost can be a great deal higher. That an earplug can be as lethal as a bullet. Most earplugs reduce noise by 30-some decibels. This is helpful with a steady, grinding background din — a Bradley Fighting Vehicle clattering over asphalt (130 decibels), or the thrum of a Black Hawk helicopter (106 decibels). Thirty decibels is more significant than it sounds. Every 3-decibel increase in a loud noise cuts in half the amount of time one can be exposed without risking hearing damage. An unprotected human ear can spend eight hours a day exposed to 85 decibels (freeway noise, crowded restaurant) without incurring a hearing loss. At 115 decibels (chainsaw, mosh pit), safe exposure time falls to half a minute. The 187-decibel boom of an AT4 anti-tank weapon lasts a second, but even that ultrabrief exposure would, to an unprotected ear, mean a permanent downtick in hearing. Earplugs are less helpful when the sounds they’re dampening include a human voice yelling to get down, say, or the charging handle of an opponent’s rifle. A soldier with an average hearing loss of 30 decibels may need a waiver to go back out and do his job; depending on what that job is, he may be a danger to himself and his unit. “What are we doing when we give them a pair of foam earplugs?” says Eric Fallon, who runs a training simulation for military audiologists a few times a year at Camp Pendleton. “We’re degrading their hearing to the point where, if this were a natural hearing loss, we’d be questioning whether they’re still deployable. If that’s not insanity, I don’t know what is.”

For that reason the US military has been experimenting with what it calls ‘Tactical Communication and Protective Systems‘ (‘Tee-caps’, shown above): ear protectors that incorporate radio communications.  They are a response both to the cacophony and the geometry of war:

No one, in the heat of a firefight, is going to pause to take off her helmet, pull back her ear, insert the plug, and repeat the whole process on the other side, and then restrap the helmet. There’s time for this on a firing range, and there might have been time on a Civil War battlefield, where soldiers got into formation before the call to charge…  You knew when the mayhem was about to start, and you had time to prepare, whether that meant affixing bayonets or messing with foamies. There’s no linear battlefield any more. The front line is everywhere. IEDs go off and things go kinetic with no warning. To protect your hearing using earplugs, you’d have to leave them in for entire thirteen-hour patrols where, 95 percent of the time, nothing loud is happening. No one does that.

Second, sounds can intimidate – sometimes deliberately so – but they can also be reverse-engineered to reveal the geometry of violence.  One obvious example is the use of sound-ranging to locate artillery batteries on the Western Front in the First World War; but less obvious, and of critical importance, soundscaping can form an important part of a forensic investigation into crimes of war. This brings me to yet another mesmerising project from Eyal Weizman‘s Forensic Architecture agency. Eyal explains:

In 2016 Forensic Architecture was commissioned by Amnesty International to help reconstruct the architecture of Saydnaya – a secret Syrian detention center – from the memory of several of its survivors, now refugees in Turkey.

Since the beginning of the Syrian crisis in 2011, tens of thousands of Syrians, including protestors, students, bloggers, university professors, lawyers, doctors, journalists and others suspected of opposing the regime, have disappeared into a secret network of prisons and detention centers run by the Assad government. Saydnaya, located some 25 kilometers north of Damascus in an East German-designed building dating from the 1970s, is one of the most notoriously brutal of these places.

Torture has become routinised there – and not as a weapon in the grotesque arsenal of ‘enhanced interrogation’ (which, for any Trump fans who have stumbled into this site in error, has been demonstrated countless times not to work anyway).  Amnesty could not be clearer:

There are no interrogations at Saydnaya. Torture isn’t used to obtain information, but seemingly as a way to degrade, punish and humiliate. Prisoners are targeted relentlessly, unable to “confess” to save themselves from further beatings. Survivors say they dreaded family visits as they were always followed by extensive beatings.

Eyal continues:

As there are no recent photographs of its interior spaces, the memories of Saydnaya survivors are the only resource with which to recreate the spaces, conditions of incarceration and incidents that take place inside.

In April 2016, a team of Amnesty International and Forensic Architecture researchers travelled to Turkey to meet a group of survivors who have come forward because they wanted to let the world know about Saydnaya.

To understand the role of sound in the investigation, what Eyal calls ‘ear-witnessing’, here is Oliver Wainwright writing about the project in the Guardian:

“Architecture is a conduit to memory,” says Weizman, describing how an Arabic-speaking architect [Hania Jamal] built a digital model on screen as detainees described specific memories and events. “As they experienced the virtual environment of their cells at eye level, the witnesses had some flashes of recollection of events otherwise obscured by violence and trauma.”

Inmates were constantly blindfolded or forced to kneel and cover their eyes when guards entered their cells, so sound became the key sense by which they navigated and measured their environment – and therefore one of the chief tools with which the Forensic team could reconstruct the prison layout. Using a technique of “echo profiling”, sound artist Lawrence Abu Hamdan was able to determine the size of cells, stairwells and corridors by playing different reverberations and asking witnesses to match them with sounds they remembered hearing in the prison.

“Like a form of sonar, the sounds of the beatings illuminated the spaces around them,” says Abu Hamdan. “The prison is really an echo chamber: one person being tortured is like everyone being tortured, because the sound circulates throughout the space, through air vents and water pipes. You cannot escape it.”

Oliver continues:

Saydnaya detainees developed an acute aural sensitivity, able to identify the different sounds of belts, electrical cables or broomsticks on flesh, and the difference between bodies being punched, kicked or beaten against the wall.
“You try to build an image based on the sounds you hear,” says Salam Othman, a former Saydnaya detainee, in a video interview. “You know the person by the sound of his footsteps. You can tell the food times by the sound of the bowl. If you hear screaming, you know newcomers have arrived. When there is no screaming, we know they are accustomed to Saydnaya.”

Documenting what is happening provides an essential platform for political and eventually legal action against those responsible.  You can joint Amnesty’s campaign here (scroll down).  Please do.
