Earlids of the early 1900s (11/21/2024)

Earlids of the early 1900s (with image of an ear)

The question of earlids being on my mind, and the airport being boring so boring, I decided to troll around the historical corpus of writings and see what earlids meant to the world before R Murray Schafer brought them to our habits of modern thought. I have five examples for today’s post, each doing something different.

EDISON – EARLIDS AS CONCENTRATION
The first is an anecdote about Thomas Edison. Many of us remember that he had been made partially deaf by maltreatment – a box to the ears from which he never fully recovered.

In our “earlid” anecdote, the interviewer asks Edison about his deafness, and he (like my exam-taking sister of my earlier earlid post) finds the concentration that partial deafness affords to be a strength. He’s asked if he plans to take the surgery which medical wisdom of the day thought would provide a “cure.” His response? “What! And give up the great advantage I have over the rest of you fellows!”

The interviewer then opines: there is a strong need, he thinks, for earlids as well as eyelids in this world.

In this world, then, earlids provide a form of concentration. They’re akin to headphones, filtering out the irrelevant so one can think one’s thoughts in peace.

TELEPHONE – EARLIDS AS SHUTTERS
Another take comes from the same journal, responding to the new technology:

This telephone business brings out strongly another of those little defects in the design of the human body which are becoming apparent nowadays. The ear is an exceedingly intricate and generally satisfactory piece of apparatus, but it was its limitations. Occasion has been taken before to speak of the regrettable absence of earlids for the shutting out of unpleasant sounds. The man at the telephone to whom some one else is trying to speak at the same time suddenly discovers that although he has two ears they will not work separately. It looks like a waste of natural material for a man to have two ears and to be obliged to listen with both at once. How much better it would be if he could listen to the telephone with one and take in conversations in his immediate neighborhood with the other!

So, if earlids could shut out unwanted sounds, we could use them to mute the external world while we communed on the telephone. Of course, here a century later, that’s such a habit that it’s now practically invisible. The anonymous observer of the earlier 20th century had a better outcome in mind, though: wouldn’t it be better if we could listen to two conversations at once? (I suspect that our Gen-Z colleagues would think that under-ambitious! So much swiping! So many intersecting worlds! So many simultaneous windows open!)

GOSSIP – EARLIDS AS A MORAL TOOL
Medical doctor and essayist George Abbott, on the other hand, is thinking about earlids as a doctor’s tool – to handle preventative moral intervention. In a column devoted primarily to the glass dropper method of cleansing the ear with enzymol, he tells a story about earlids that he suggests be shared with the child patient. Two college co-eds were talking, and one asked the other, “would it not be fine if there were earlids as well as eyelids? Then when anyone said anything against one, they could shut their earlids.” Her interlocutor is having none of it: “yes, but who’d shut them?” We’re nosy, in other words, we want to know.  

Ah, Abbott encourages us, the skillful doctor could then use this story to reinforce the important moral lesson: the pus he’s cleaning out with the enzymol is not as poisonous as vile stories, and the caring doctor should thus tell the child: stay clean and pure; close your earlids against gossip. To him, pretending you have earlids is the moral choice. He wants his colleagues to share both story and lesson, because a doctor is like a godfather to the child. He’s bowing to Ovid’s discussion of rumor (Metamorphoses, Bk XII), of course, and for him, earlids (Ovid’s closed doors on the threshold) are about ignoring “vile stories” and tending only to good and moral thoughts.

BABIES AND THE ABSENCE OF EARLIDS (Saleeby’s theory of 1905) – EARLIDS AND URBAN NOISE, EARLIDS AND EVOLUTION
A surprisingly influential observation about the human absence of earlids was made by eugenicist and physician Caleb W. Saleeby. Two years before he helped to launch the Eugenics Education Society (yeah, ick), he had already developed a popular presence in the press with his medical opinings. One of them, that received quite a few follow-ups, was an essay that investigated (and I use that term loosely) why it is that humans lack earlids:

For sleep it is desirable to exclude light and sound: but whilst we have eyelids, no apparatus for closing the ears is known save, I believe, in certain animals which inhabit the sea, and whose ears are of small auditory importance. In these days, when barrel organs assail us with the “Ave Maria,” playing Bach’s accompaniment in G and Gounod’s air in somewhat more than G, and when the motor car makes night hideous, one sighs for earlids.

And I have even wondered why natural selection has not so endowed us: for it might seem an advantage to be able at will to protect one’s nervous system from sound as from light.But it occurred to me that I had not appreciated the significance of the “infant crying in the night, and with no language but a cry” – crying, however, not for the light but for its food. It would be a sorry business if a child had to rely for its nocturnal refreshment upon the willingness and ability of its mother to keep awake, or to waken spontaneously when wanted. This, perhaps, may partially explain our deprivation of earlids.

Crocodilian researchers would protest at the characterization of their field as “small auditory importance” since, as I’ve mentioned earlier, the excellence of hearing, its tracking ability which has proven to include directional hearing via pressure differential in the middle ear cavities – which is cool! A single alligator ear can tell direction! Wow! (Bierman et al. 2014).

But also, Saleeby gives us context. We want earlids because of urban noise, and that noise is defined in part in musical terms – the oppression of an out-of-tune barrel organ playing a too-popular hit – and then in technological ones, with the nighttime noise of that newfangled automobile a contributor to what we moderns might call noise rot – the ugly deterioration of a once pristine soundscape.

And why don’t we have them? Because mothers need to tend to crying babies. It’s an adaptive trait, he’s claiming, to not be able to shut out noise at night.

Of course, people pushed back on his claims of sleep; his notion that humans only indulged in surface sleep is easily debunked, and his gendering of the nighttime-listening claims are equally fraught. But one didn’t need evidence to be influential, and that influence even made its way across the channel into France.

PARIS 1907: EARLIDS, URBAN NOISE,  AND THE LUDDITE PERSPECTIVE
In a short column for The Musical Courier, an anonymous essayist picks up Saleeby’s complaints about urban noise. In doing so, he evokes “the agitation over here [Paris] on the noises of cities,” and claims that concern about these intruding noises “has reached a point of insisting upon official investigation.” We’re in crisis because, he points out, “The automobile and the motor-bus are not respecters of the public ear.” Once upon a time, the horse car ran with “a minimum of noise,” but now all those modern inventions are a hazard, “both as to dust and to noise.” The essayist notes that there’s been scientific investigation of the sanitary aspects of noise, and calls (sensibly) for tires that will minimize noise in the landscape, but he’s also quick to jump to the “nervous ailment” that is the result of all that newfangled stuff. Our health is at risk from all these infernal machines.

The author cites Saleeby by name (and preaches his brand of evolutionary thinking), but is perhaps a bit more nuanced (or more aware of others’ critiques about sleep) than was Saleeby himself. The Musical Courier correspondent reminds the reader that the noise “of the ‘bus, of the elevated, of the milk cart, of the rumbling coal cart, can be dismissed by the mother and will not affect her sleep, but only a movement, a change in the rhythm of the breath of the baby, and she is awake.”  We can tune out the systematic background noise, but the unexpected or the worrisome sound will intrude and poke us awake by way of our sense of hearing.

What the author does do that is important (and approved by OSHA, I’m sure!) is to consider the way in which urban noise might impact the musician. The delicacy of the musical ear, he claims, and especially its need to differentiate “infinitesimal tonal allusions,” is at risk by all this landscape noise. Even talking loudly can lead to the “corruption” of the listening faculty. How much more dangerous is that “havoc” from the technological noises descending “into the streets and roads every day.” This is at heart a Luddite perspective; the new technology is bad and damaging, and we should do what we can to shut it down. The early call in the essay for better tires (that would make less noise) gives way for an imagined future of air travel, the “only relief” that the writer can imagine.

(He’d clearly never yet heard an airplane’s roar! On the early development of flight in Europe, see https://applications.icao.int/postalhistory/aviation_history_early_developments_in_europe.htm. The air is imagined more as a hot-air balloon kind of space than one with motors and engines to clutter up the soundwaves. Oh, the irony of thinking about this in an airport context! Sooooo much noise!)

I spend time on the Musical Courier essay because it does raise the issue of soundscape in the context of the earlid theme that’s got my attention at the moment. This author positions the earlid as a kind of Luddite tool, one that could have blocked technological noises specifically, not just urban ones. He isn’t interested in blocking out “unwanted” noise, but rather the damaging noises that come from these newly invented tools that are overrunning the landscape. Motors cause noise and dust. The practical solution is to investigate and regulate them; the fantastical solution is to invent our way out of the damaging sound-moment in history. This isn’t pure Luddite --there’s perhaps a salvic capacity in technology of the far future – but it’s at the least a technology-resistant perspective. Motors here are all noise and no benefit, and their appeal is invisible. We are left to their noisy consequences.

CONCLUSION
These five glimpses of earlids from the first decade of the twentieth century are interesting to me for several reasons. 

First, the conceptual notion of the earlid is clearly in the early twentieth-century conversation; it’s coming up in engineering, in medicine, and in music. That cross-disciplinarity suggests the power of metaphor as meme, spreading and shaping thinking of the period. (Thank you Peter Bailey 1996 -- important legwork on how to think about such things in history!) 

Second, the multivalency of earlids is important too, for they are at once moral filters and anti-technology assessments, a screening tool or a focusing one. They – in their absence -- are even read as an evolutionary tool. The earlid as a point of reference shows the crossover of various strains of thought in a time of intellectual ferment. 

Third, these imagined earlids reflect early 20th-century anxieties about controlling soundscapes and are in a way a precursor to today’s focus on noise-canceling technologies. We have headphones and those little foam dispensaries in libraries and at construction sites; we practice mindfulness and build apps that let us move away mentally from noise and chaos to at least an inner stillness. They had words, and complaint processes, and regulations, and essays. But what is clear to me from the earlid discussions then and now is that we all share a concern about the soundscapes we inhabit.

I am (not) a crocodile: Earlids and the thinking person (11/15/24)

Image of a crocodile in lights from ZooLights at Lincoln Park Zoo

Earlids, or rather their absence, are a common trope of Soundscape literature. The idea is a stand-in for sound’s penetrative abilities; without earlids, the narrative goes, we cannot block noise.

The idea takes shape in its modern iteration from R Murray Schafer’s The Soundscape (1977/r1994, p. 11):

The sense of hearing cannot be closed off at will. There are no earlids. When we go to sleep, our perception of sound is the last door to close and it is also the first to open when we awaken. These facts have prompted McLuhan to write: “Terror is the normal state of any oral society for in it everything affects everything all the time.” The ear’s only protection is an elaborate psychological mechanism for filtering out undesirable sound in order to concentrate on what is desirable….

While it is Schafer who is most often quoted, McLuhan and Fiore had introduced the image a decade previous in The Medium is the Massage (1967/r2001 p. 111): “We can’t shut out sound automatically. We are simply not equipped with earlids.” (Emphasis mine).

Neither “willful” closing of the ear (Schafer) nor an “automatic” closing (McLuhan) being allowable by virtue of our biology as humans, we moderns must inevitably be bathed in the surround-sound of the world around us. Or so we have come to assert.

Well, crocodiles do have earlids. This somewhat (to me) astonishing revelation has been widely discussed since the mid-nineteenth century. Crocodiles, Wever determined in 1971 (PNAS), have excellent hearing, which is best in the midrange and drops off strongly in the lower register. The tympanic membrane or “round window membrane,” he points out, is protected by the earlids that shape out the crocodile’s head.  Likewise, Montefeltro, Andrade and Larsson in 2106 pursued a comparative study (J of Anatomy 2016) in multiple species in the crocodilian group in which they investigate the “Large meatal chamber concealed by a pair of muscular earlids that shape a large air-filled middle ear chamber.”

Earlids as muscular tools, protective of excellent hearing: I didn’t know that I secretly wanted to be a crocodile.

Or maybe I already am.

Let me back up. One of the other commonalities of the “earlid” discussion is the notion that the hearing-impaired might have the human equivalent in their hearing aid devices (for example, Myers 2000, p. 13). I know how that works from my sister (who is legally deaf). She used to talk about reaching up to click off all the classroom noise during exams. (She may also have confessed to clicking off a scolding or two as well, ahem.) She wound up valedictorian, so there might be some use to that strategy.

But I’m not that person. Rather, I have the Schafer form of “earlid,” that focused intensity that slams shut the world around us. I “go deaf to the world” when reading a particularly good novel, for instance (T. Kingfisher, George Eliot, Nicola Griffith, Kelly Barnhill, Casual Farmer, Jane Austen, S.A. Chakraborty…. And whatever else floats past my event horizon on the book front). The same zoning out practice happens when I pick up my scholarly projects. I have “come to” with (adult) children standing patiently in front of me holding paper signs saying “Mom?” (Okay, it was funny, but it happened more than once, eek).

The interesting thing about this kind of concentration is that I do obviously process sound at some level. “Were you talking to me?” and “Was that a siren?” and “Do we need to take cover from the storm?” are a few of the questions I’ve had on my lips as I’ve emerged from my stupor.

The sound was there. My brain took it in. But the slammed-down wall of concentration didn’t let any of those sounds penetrate my concentration. The earlids of the mind are clearly located somewhere between one’s ear drum and one’s consciousness, and they work even better than eyelids, which leak light. The time delay for even urgent sounds to penetrate can be 90 seconds or so -- all my sound questions are justifiably phrased in the past tense. A flash of lightning can grab me out of the concentration space; the rumble of thunder is less likely to do so.

This experience of closed earlids is, at least for me, separable from flow. Flow can happen with or without the earlids closed. I frequently encounter flow while on the trail, for instance, but part of that flow is processing the forest sounds and leaning into the acoustics of the landscape. Flow is also enjoyable in music – whether I’m listening to a recording or attending a concert, following a score or recreating the music in my head. There are lots of details of the work to which I am listening coming in on that emotional-analytical channel, but I can do it with earlids open or earlids closed. More often, music is an earlids open kind of experience for me; I am in the music but I am reachable (sometimes frustratingly so – sorry, family!).

But sometimes the music is earlids closed; only the music is in the brain’s consciousness, and it is all-consuming, fully occupying all attention and setting up for the delivery of those perfect moments that are the “reason” for the passage, the movement, the symphony as a whole; the coloratura run, the swell on the held note, the fade into ineffable beauty.

Earlids closed happens most naturally with music I know and love, but it can sometimes happen with music I am hearing for the first time, and even with music I don’t like. Working on developing an interpretive understanding of the music seems one trigger; following the “idiom” of the music as if it were another dialect and I was straining to follow its vocabulary is another. Both include an intellectual component, so maybe that’s part of the earlid mechanism – a left-brain kind of processing. And maybe there’s an intellectual component to loving that Brahms moment too: I am following the music in the moment, but also projecting the familiar music’s future, so that I am having a multi-temporal appreciation of the particular moment, and surely that must have a left-brain “understanding” component as well as the right-brain “O what beauty!” element.

Bringing it back to that book-reading, I suspect that there’s both an element of analytical and appreciative activity that plays into the earlid function. I follow the story, imagine its world, and revel in its revelations. Busy brain, busy brain, no room for distracting thing like conversations about what we should do for dinner or whether the computers should be unplugged in advance of the storm. The emergency isn’t here yet; my brain has its earlids tightly closed.

These three cases, then, seem to suggest that flow – that highest form of concentration – is distinct from the earlid function. Sometimes flow is *about* sound, either at large (hiking) or in selective part (music). Sometimes earlids are open (hiking and music) and sometimes they are closed (music and some of the best reading). I can read in a flow state that is interruptable (if with some irritation), or in a flow state that is not, except through touch or patience. The earlids are a different KIND of concentration from “flow,” I suspect, and bicameral in its function. (I’m betting it involves both left and right brain – and those both as cause of earlid clamping and as effect.)                       

What am I arguing? I believe that like a crocodile swimming in the ocean, or like my sister shutting off her devices, my brain can use its muscles to shut out the unnecessary distractions.

Whether my family agrees with my brain’s judgment about what qualifies as “unnecessary” (and thus when my earlids can be shut) is another question entirely!
