Body Sonic / Coronavirus Surroundsound

There’s a great moment in a recent article by Jace Clayton, who reviews an installation by DJ and musician Carl Craig for Artforum, where Clayton talks about music’s relationship to empty space.

There is something of “a sonic axiom,” Clayton writes: “Amplified music sounds terrible in empty rooms. The less stuff there is in any given space, the more sound waves will bounce around the walls and ceiling and glass, losing definition as they both interrupt and double themselves. The resulting audio is smeary, muffled, and diffuse. However, when the same space fills with bodies moving around, those waves are absorbed, dampening those irksome reflections and allowing us to hear the sound more powerfully and in far greater detail.”

The effect is such that “the only thing that could make [music] sound better is people.” Bodies make music better—a second sonic axiom, as well as an optimist’s call for more social listening. In other words, your music will sound better the more people you experience it with. Hang out with others. Be bodies. Share.

In any case, Clayton’s piece went online a couple weeks ago but I find myself thinking about it almost daily, as the acoustic effects of the coronavirus lockdown become clear in cities around the world.

“As the pandemic brought much of the crush of daily life to a halt,” the New York Times reported, “microphones listening to cities around the world have captured human-made environments suddenly stripped of human sounds.” To put this in Clayton’s terms, cities are now spaces without bodies.

Think, for example, of Francesca Marciano describing “the new silences of Rome” in an age of coronavirus, or the New York Times itself pointing out how, in Manhattan, “the usual chaos of sounds—car horns, idle chatter and the rumble of subways passing frequently below—[has] been replaced by the low hum of wind and birds. Sound levels there fell by about five decibels, enough to make daytime sound more like a quiet night.”

There is an interesting paradox at work here, though, in terms of a widely reported belief that birds appear to be singing louder than ever before: birds are actually quieting down now, as they have less competition to out-sing. As the NYT writes, this is “because they no longer have to sing louder to be heard over the racket of the city, a behavior, known as the Lombard effect, that has been observed in other animals, too.”

I’ve written at length about sound and the city elsewhere, but one of my favorite pieces on this was a short profile of acoustic engineer Neill Woodger, then-head of Arup’s SoundLab, published in Dwell way back in June 2008.

There, Woodger made the point that, as we transition to electric vehicles, which will remove the sound of the internal combustion engine from our cities, we are being given a seemingly once-in-a-lifetime acoustic opportunity: to redesign urban space for sound, highlighting noises we might want to hear—birdsong, bells, distant train whistles—and helping to excise those we do not.

The coronavirus, it seems, has inadvertently set the stage for another such sonic opportunity. Our global urban lockdowns have all but stripped our cities of “bodies moving around,” in Clayton’s words, such that our streets now sound quite eerie, as if replaced by uncanny muted versions of themselves, or what Marciano calls “an atmosphere of peaceful suspension, as when it snows and everything is wrapped in cotton wool.”

Much has been made of how temporary design interventions in response to COVID-19—things like wider sidewalks, outdoor cafes, streets liberated from cars and opened up to children, families, and the elderly—might become permanent.

In this context, what permanent acoustic shifts might we hear coming from all this, as well?

Have Clock, Will Travel

There’s a line in The Hunt For Red October where a submarine navigator jokes, “Give me a stopwatch and a map, and I’ll fly the Alps in a plane with no windows.” I was reminded of that comment by reports of a new atomic clock that will allegedly enable “futuristic navigation schemes”:

“Every single spacecraft exploring deep space today relies on navigation that’s performed back here at Earth,” said [Jill] Seubert, who’s based at NASA’s Jet Propulsion Laboratory in Pasadena, Calif. Earth-based antennas send signals to spacecraft, which the spacecraft echo back. By measuring a signal’s round-trip time within a billionth of a second, ground-based atomic clocks in the Deep Space Network help pinpoint the spacecraft’s location.

With the new Deep Space Atomic Clock, “we can transition to what we call one-way tracking,” Seubert said. A spaceship would use such a clock onboard to measure the time it takes for a tracking signal to arrive from Earth, without having to send that signal back for measurement with ground-based atomic clocks. That would allow a spacecraft to judge its own trajectory.

One might say that the ship is navigating time as much as it is traveling through space—steering through the time between things rather than simply following the lines that connect one celestial object to another.

The general problem of ship orientation and navigation in deep space is a fascinating one, and it has led to ideas like using “dead stars” as fixed directional beacons, a kind of thanato-stellar GPS. This is “the long-sought technology known as pulsar navigation,” Nature reported last year. “For decades, aerospace engineers have dreamed of using these consistently repeating signals for navigation, just as they use the regular ticking of atomic clocks on satellites for GPS.” You head toward something that’s only consistent because it’s dead.

There is something really interesting here, where human navigators and their far-flung machines are confronted with a landscape so vast it is all but devoid of local landmarks. Imagine the cognitive skills necessary for early humans to wander forth, on foot, across colossal and empty steppes, long before modern navigational tools, or picture autonomous, near-frozen hard-drives falling endlessly outward toward stars they might never reach: these scenarios lend themselves to metaphor just as much as they present real-world cartographic problems masked as an encounter with landscapes impossibly huge.

A landscape so big it becomes time, and only a clock can conquer it; or a space so empty, its only fixed points are long dead.
