The Loudness War: Sound and Control in Civil Protests

The use of sound as a weapon, whether physical or psychological, is by no means a novel concept. In World War II, German scientists experimented with a ‘sonic cannon’ that emitted a sub-bass frequency believed powerful enough to cause nausea, organ compression and death within a minute. During the Vietnam War, American helicopters were fitted with a loudspeaker dubbed ‘The Curdler’, which unleashed the sonic equivalent of a premonition of ceaseless purgatory on enemy troops below:

Long Range Acoustic Devices (LRADs) are arguably the latest in this line of sonic technology. Originally marketed as long distance communication carriers by their manufacturers American Technology Corporation, they are capable of delivering a shrill 145dB tone over hundreds of metres. They most often serve as deterrents, defending coastlines and cargo ships against pirates or repelling birds from commercial and military airfields.

LRADs are also being adopted for other, more confrontational purposes, such as the ongoing military conflicts in Iraq and Afghanistan. Perhaps more troublingly, recent years have seen a greater use of LRADs in instances of civil unrest.

While LRADs were part of the NYPD’s policing strategy for the 2004 Republican National Convention, the first operational deployment on US soil was at the G20 summit in Pittsburgh in September 2009 to disperse crowds of protesters (see below). They have since been used in the Occupy Wall Street movement (2011), the NATO summit in Chicago (2012) and during the racially charged unrest that followed the killings of Michael Brown (Ferguson, Missouri) and Eric Garner (New York) by police officers in 2014.

These events and others like them appear to signify a marked shift in tone and emphasis in the discourse relating to maintaining public order. What does the rise in the use of sound as a means of control say about attitudes to political dissent, public spaces and sound itself?

In the case of Pittsburgh, government-allocated protest permits and free speech zones – ideally used to strike a balance between freedom and public safety – were strategically issued (or refused outright) so that protests were confined to areas well away from the summit itself. These sites were then policed in an at times hostile manner that meant demonstrators stood a far greater chance of criminalisation (Sery 2013). By the time the LRAD was activated, the very act of protest had already been constructed as a menace to the public.

De Bartolo (2008) argues that this reframing of social spaces as ‘sites of danger’ began in the post 9/11 discourse of police knowledge (i.e. knowledge acquired through experiences of similar events), where invocations of threat and terror increasingly informed the way in which non-violent protest movements were viewed and handled. As this internally circulated NYPD Situation & Threat Assessment from the aforementioned Republican National Convention illustrates, these perceptions are constructed as reality through the advice and profiles issued to the police force:

Currently there are no specific threats against the RNC. However, political conventions and elections are potential terrorist targets. The vehicle borne improvised explosive device remains one of the most readily available and frequently used tactics by terrorists worldwide. The use of hazardous materials, including chemical and biological weapons, poses a significant threat as well.

Additionally, it is anticipated that New York City will see a volume of protest activity not seen in decades. Organizers from United for Peace and Justice predict that 250,000 people will participate in their march and rally scheduled for August 29th.

While the vast majority of the participants will be peaceful, the sheer size of this event will place a tremendous strain on the department’s resources and severely impact vehicular and pedestrian flow in midtown.

Open source information indicates that there will be some individuals and groups, who advocate violence in opposition to the government, seeking to engage in criminal conduct that could significantly endanger public safety.

NYPD Executive Summary in De Bartolo (2008) (emphasis added)

By shrouding neutral information in redolent terrorist discourse, the document de-legitimises and vilifies protesters and paves the way for more extreme ‘command and control’ policing including devices such as the LRAD. Incidentally, no dangerous devices were found during the event and despite over 1800 arrests of activists and bystanders less than 10% were charged, mostly for minor offences.

This categorisation of protestors doesn’t simply entail making allusions to terrorism. Looking at the instances where LRADs were used against demonstrators, it is not difficult to see how bodies charged with maintaining social control can typecast those involved: the poor or disadvantaged, ethnic minorities, other races or nationalities (outsiders), the morally aberrant, political agitators.

Whether any of these labels are grounded is immaterial. Firstly, the authority and autonomy afforded to the police force creates an imbalanced power dynamic that is self-sustaining; it defines itself and shapes the roles and identities of the social actors around it. Secondly, language – that of danger, deviance and the unknown – is a powerful means of generating consensus for solving social problems (Maneri and ter Wal 2005).

The use of LRADs continues to draw criticism from human rights organisations who deem them ‘less lethal’ rather than ‘non lethal’ weapons (Lewer and Davison 2005). Unlike with tear gas and bullets, the immediate effects of sound are largely invisible, but they can still be irreversible. Journalists and activists exposed to LRAD at an Eric Garner protest in New York recently sued the police for civil rights violations, citing the use of excessive force. The City of Pittsburgh paid a $72,000 settlement to a professor who suffered permanent hearing damage at the G20 summit protest.

Though there is still an ambivalent attitude towards the weaponisation of sound to maintain public order, there are some important reasons why LRADs have gained such rapid acceptance among law enforcement agencies. Under the constant gaze of international media, the use of LRADs is rendered exceptional: it gains legitimacy by existing outside of society’s conventional understanding of policing and violence.

Zuazu (2015) sees the ready adoption by authorities as a cynical attempt to ‘humanise and distinguish’ these powerful acoustic devices from the most extreme forms of sound torture*, even though they both appear to operate outside of any accountability. Consider that the initial definition of LRADs as loudhailers exempted them from the same rigorous legal and governmental scrutiny faced by manufacturers of state-endorsed lethal weapons. In addition, over a decade since their introduction there is still no official police policy for their use.

Driven by a one-sided, fear-based discourse, the movement away from democratic forms of policing towards paramilitary ones is having a discernible effect on the way protests and activists are being assessed, enabled/disabled and portrayed. LRADs occupy an ambiguous position, both in the arsenal of police strategies and in the public consciousness. However, what is clear is how the aggressive use of sound to control public spaces and secure compliance with authorities is indicative of a decreasingly interpersonal approach to policing and public relations. Perhaps this aspect of the ideological shift is the most worrying of all: that LRADs may be part of a wider erosion of public safety, the right to assemble and to exercise free speech.

* Note: For the purposes of this article, the use of LRADs in mass protest is viewed as distinct from other forms of sound torture, such as those used on individual prisoners in the detention camps at Guantanamo Bay after the 9/11 terrorist attacks.

Sonically (Re)imagining China: Fatima Al Qadiri’s ‘Asiatisch’

Asiatisch (German for ‘Asia’), the 2014 debut of Senegal-born, Kuwait-raised musician Fatima Al Qadiri, is described on her website as a simulated road trip through an imagined China. I am intrigued by the idea of sonically imagining a country that you’ve never visited using only the cultural, political and social reference points laid down by other cultures which, of themselves, are not necessarily concerned about replicating the place with any degree of faithfulness.

This album appears to be contributing to a discourse that explores Western popular culture’s appropriation of Asia. Consider the status of martial arts movies in post-war American youth culture; the extolling of ‘traditional’ practices and ancient wisdom (as found in fortune cookies?); anime and comic book fetishism; largely negative/Communist screen roles (from Cheng Zhi in 24 and Lau in The Dark Knight to the tropes that litter Disney movies – although this does appear to be changing as China in particular becomes a more lucrative market).

Al Qadiri makes a good point about what for many Western children is their first exposure to East Asian music/culture, the piano piece ‘Chopsticks’:

“I feel like my first engagement with Chinese culture was either through Looney Tunes or a Disney cartoon, one of the two. Musically, I wanna say probably (laughing) ‘Chopsticks’. You know, I feel like ‘Chopsticks’ is like the consummate imagined Chinese piece of music. Even the title!”

Cliff (2015)

Asiatisch’s overarching aesthetic takes familiar symbols of China – flickers of zither, pentatonic scales, ethereal pipes and percussion – and weaves these into a stark, synthetic vision of a country: a vision that’s cold to the touch. I hear it as a sound that simultaneously invites and distances, that professes authenticity and a spiritual connection with its source material, but then coats every surface with an almost plasticated sheen, the equivalent of an ‘ethnic’ craft shop housed in a sleek, ultra-modern chrome-and-glass shopping mall.

The juxtaposition of expression and remoteness can be heard in the twitchy, robotic/not robotic interjections throughout ‘Wudang’, and most notably on the cover of Prince’s ‘Nothing Compares 2 U’. A deeply affecting vocal in its most well-known form, Helen Feng delivers it in a Mandarin-flavoured gibberish. It’s worth noting that the title of this version (‘Shanzhai’) literally translates as ‘fake goods‘.

As alien as the music often sounds, it seems natural that the sonic palette for much of the album is derived from sino-grime. A muscular South/East London sub-genre of dance music from the early 2000s, it yielded some great instrumentals by transferring uninformed notions of Eastern mysticism, motifs and instrumentation onto experiments with mutant bass and sparse, glacial synths. On Asiatisch the listener is clearly being ushered into a fantasy-realm of music, but one that asks questions of the West in our handling of China’s cultural assets, our perception of its value.

When I was a music teacher in the UK some years ago, I remember the sharply contrasting attitudes towards the canon of Western classical music – a definitive, sacred, ever-relevant oeuvre – and the facsimiles of Chinese and African music that were all too often presented as the ‘other’: exotic, rudimentary, fossilized. Thompson (2002) expounds on this idea, asserting that:

[the canon represents] a selective and exclusive tradition that embodies certain values, notably Western ideals and standards of truth and beauty. Afforded authority and status over time, it reflects the interests of the dominant groups in society… In contrast, the ‘other’ is a category traditionally associated with limited position and power.

Thompson (2002)

Upon reflection, I now view those experiences of classroom ‘world music’ as an artificial construct, sometimes watered down to the point of near irrelevance. As Al Qadiri puts it, ‘a projection of a dominant culture onto another marginal one’. Yet, even as the music reimagined the countries it represented, to my students perhaps it was unquestionably authentic. This is what draws me to Asiatisch; a place where it’s possible to hear the sound of a cultural and musical identity being appraised and renegotiated from outside of its borders.

Listen to Asiatisch here.
