The Acoustic Sponge of White Noise

While some sources of ambient noise can’t be stopped, communicators seeking the ideal environment will do what they can to minimize it.

Sound produced by a person is as fragile as a feather.  As a slight disturbance of air pressure it exists only in the moment, decaying almost instantly.  And at normal levels it is often no match for the environmental noise we accept as the price of living in hives of activity.  Humans produce sound as speech over a frequency range of roughly 100 to 5000 cycles per second.  That’s a fairly narrow range in comparison to what the ear is capable of sensing.  Moreover, the relative volume of our speech is modest. We need to be in a small room and in good voice to generate sufficient loudness to be easily heard, somewhere in the neighborhood of perhaps 60 decibels (db).  But this measure of sound pressure increases logarithmically, so that continuous exposure to noise above 95db is sufficiently risky to be recognized as a workplace problem by OSHA.

Our ability to be the primary source of another’s attention is easily swamped   by a passing ambulance with its siren on (about 110 db), the shrieks of a child on a bus or a railway coach (95 db), or even the nearly constant drone of background music or others talking in the same general area (perhaps 40 db).

Most of the background sound in our lives is this kind of noise. Unless we are in the unlikely space of a anechoic chamber that is built to exclude all external noise (and where the only sound heard would be our own heart pumping),  we pass our days in a constant circus of external noise.  We are often not conscious of it.  Indeed, our brain is pretty good at tuning it out.  Awake from a deep sleep, and you can actually hear the ambient noise of a room quickly being “turned on” by the brain.

But here’s the challenge.  We use our voices to do a lot of important work.  We need to be heard often and clearly. Sometimes our livelihood depends on it (as in teaching, face to face sales, conducting meetings and interviews, and so on.  At other times the din of constant noise destroys the chances for making an impression, or for a family to function as a family. The requirement to compete with other “convenience” devices in our lives—dishwashers, televisions, air conditioning, another’s constant chatter—can leave us exhausted.  Nothing is more fragile than the attention of another person.

The most common source of this fatigue is “white noise:” a collection of many sounds thrown together in the environment.  Because it contains many different frequencies, white noise is a sponge soaking up whatever else is existing in the same space.  And because it does not necessarily seem loud to us, we overlook the fact that it is blocking our ability to connect with others.  Here’s a sample with its video counterpart:

The ambient sounds in your life will often be more subtle, but still disruptive of the ability to easily dominate another’s attention.  The major culprits: air handling systems in buildings, others talking at the same time, transportation traffic on the ground or in the air, even wind filtering around buildings and other natural objects.

While some sources of this ambient noise can’t be stopped, a savvy communicator seeking the ideal environment for reaching others will do what they can to minimize it.  Shutting doors and windows can help. Turning off air conditioners is sometimes possible (and a common decision in location filming when the sound crew realizes the problem).  It also makes sense to ask others in the same space to carry their conversations outside.

We use public address systems to increase the loudness of a voice.  But the better solution with a smaller group is to seek out a small room, or at least to arrange seating so that each person is just a few feet from others in the group.  Part of being successful as a communicator thus means also being at least an amateur acoustician.  As a person who lives by presenting ideas orally, I always check out the space in advance, doing what I can to make it easier to be heard.  A few months ago that meant asking a group to stand by while I ran out of the building to wave off two gardeners with noisy leaf blowers strapped to their backs.  Gas-powered motors are monster sponges that can sabotage anyone’s best efforts.

The Impoverished language of Communication Description

In communication analysis, personal dispositions are often mistakenly converted into an ersatz psychology of the other.  

One of the ongoing challenges of talking about communication is that the language we use to describe effects and outcomes is hopelessly narrow.  Unlike other disciplines that have the obvious advantage of describing the material world, the language of rhetorical description seems relatively static and impoverished.  If we believe someone had a strong reaction to something said to them, we talk about the message’s “emotional” power, as if we were saying something important and decisive. But there’s rarely been a more useless word invoked as an ostensibly meaningful term of description.  Aristotle awkwardly used the idea 2500 years ago in one of the first rhetoric texts, and it still hangs around like an unwanted guest.

I’m as guilty as the next.  For over forty year, my own works of communication analysis have been filled with words like “expressive,” “media,” “interactions,” and “feelings,” as if these ideas were precise or even proximate units of meaningful exchange.  At best, such terms are mostly empty placeholders, begging for refinement and at least some operational detail.

We clearly need a richer lexicon that more thoroughly suggests the many nuanced responses that messages can elicit from receivers. Perhaps this is an essential function that is better carried by narrative film and literature. Poetry, the novel, and even music may often give us more precise pictures of the inner mental states we produce when we address others.  Even the standard “reaction shot” that a film director chooses when one character delivers bad news to another more clearly communicates authentic effects.  A face can register what our sometimes hackneyed language misses.

For example, take the challenge of naming intentions: a subject vital to understanding what individuals can possibly mean by their actions and words.  As I noted in The Rhetoric of Intention, the resources of ordinary English language seem inadequate to address the uncertainties and possibilities of reasons behind acts. There can be no question that we possess a rich vocabulary of feelings and affective states (“upset,”  “annoyed,” “excited,” and the like).  But we have no similar linguistic depth that would give us a lexicon of rhetorical intent.  We describe another’s likely reasons in an endless variety of available verb forms (i.e., “asserted,” “argued,” “pleaded”); but there are no exact counterparts for what should be the complementary “whys” of motivation. Instead attributions are made mostly by inserting imprecise qualifiers in front of clumsy and inexact interpretations of attitude. For instance:  “He may want her to make the first move,” “She doesn’t seem to be motivated by the money,” “Maybe he’s depressed,” and so on.

It’s not difficult to explain this mismatch between an important communication principle and its paltry vocabulary. This deficit is partly a consequence of the natural human compulsion to think deterministically. In our hardened presumption to find a language of first causes that can match the sciences, we mostly fall back on the inadequate language of psychological disposition.  The lexicons of psychology function as ill-fitting surrogates used to label all sorts of personal attitudes.  It’s as if every clinical word of description—common terms like “paranoid,” “depressed,” or “anxious” –is its own self-defining effect. The idea of jealousy, for example, is explained when we conclude that it springs from “envy,” or perhaps a “sublimation” of some sort arising from within. Personal dispositions are thus mistakenly converted into an ersatz psychology of the other.  In the process, we hardly notice that the rhetoric behind these labels remains mostly unnamed.

In practical terms, we could reform our usage by promising ourselves to depend less on empty but popular fallback terms of communication description, among them: “emotion,” “media” “feelings,” “rational,” and so on.  In their place there might be better terms that incrementally move us a little closer to naming the processes of communication with more precision.  My own preference is for a lexicon that would favor terms like “meaning” and “understanding:”  what is our best estimate of what we think receivers took away from a message?—“empathy” and “acknowledgement:” can we make a judgment about whether the needs of receivers were understood by the sender?—and was the message functionally “dialogical?”—meaning that we want to know if its source strived to make the receiver a true partner in the exchange. These attempts at greater precision are small steps, to be sure.  But they are a useful start.
