Emerging from the fifth floor of the Clough Undergraduate Learning Commons, the terrace garden provides asylum to those wishing to escape the serious, and studios environment of the floors below. The arching trees carpeted by sedums and tall grasses form an oasis, perfect for intimate conversations, or gathering ones thoughts. This oasis is complemented by the sound scape’s perceptual fidelity.
The air conditioners on the roofs of Van Leer and Bunger-Henry buildings produce a ceaseless hum that defines the keynote of the terrace. The two air conditioners are distinct with one being smooth, and high pitched, and the other being dull and mechanical. The hum is quickly forgotten but its importance is crucial in overpowering other sounds that compete to reach the ear. It is also isolates different sections of the terrace allowing for a feeling of confidentiality to coexist with the terrace’s open layout and expansive views.
As a result many groups can be talking simultaneously on different parts of the terrace and it is only possible for each group to here that another group is speaking, but not the actual content. Intelligibility of the sound and semantic listing is only possible between two parties, with intimacy.
Listen for yourself!
In addition to the air conditioner’s hum the background sound is also composed of organic sounds such as the chirp of crickets and the wind rustling through the grasses and the trees. At dusk the thermal mass of the concrete radiates heat causing the crickets on the terrace to produce higher pitched and faster paced chirping then the crickets that can be heard in the grassy areas below. These organic sounds aid in the peacefulness of the terrace.
Listen for yourself!
Every so often a honk of horn, a train blowing its whistle, or a group of students bursting out into laughter on the side walks below, will cut through the background sound. Due to the infrequency of these other sounds, they tend not to detract from the intimacy. They rather prevent the feeling of complete isolation, by forming a moment of connection to others outside of the terraces immediate space.
The intimacy of the terrace relies heavily upon the role perceptual fidelity plays in the space. Perceptual fidelity is what causes the background sound to be the dominant factor in deciding how the space works. Perceptual fidelity reduces the ability of unique sounds to distract due to the distance between the source and point of audition. Perceptual fidelity also explains the terraces ability to use the background sound to split the terrace into sections of confidentiality.
The 4th floor of the Clough Undergraduate Learning Commons is a study location frequented by many Tech students. The space is always “buzzing” with a white noise that provides the ideal backdrop for finalizing a lab report due to the 5th floor at noon or reviewing for that calculus quiz in Skiles at 3:05. Many noises contribute to this soundscape—the ding of elevators, the clamor of feet ambling up and down the central staircase—but the babbling of voices is the keynote sound that makes the Clough a perfect place to study.
Though conventional wisdom preaches utter silence as the best promoter of productivity, the noise of the Clough offers something that silence cannot—stability. In a sparsely populated soundscape, such as the Library, the squeak of a chair can radically alter the entire soundscape, shattering concentration like a pane of glass. In contrast, the chatter of the Clough creates a soundscape that is difficult to alter, discouraging selective hearing and promoting sound as an aid to productivity. Voices from all levels of the building bounce from concrete face to concrete face, mixing and mingling to create an unintelligible hum of conversation. The constituent signals comprising this hum have been blended so thoroughly that decoding any information regarding their original content or source is near impossible. It is a uniform and indistinct sound that does not lend itself to semantic or causal listening and allows the brain to focus fully on comprehending a text or composing a paper.
Yet, the amalgam of human voice that is the soundmark of the Clough is not entirely void of meaning. It retains a bustling timbre that is insidious. It chants “there are things to be done.” It energizes on the subconscious level and provides the vigor necessary to accomplish the tasks at hand. The next time you are getting ready to crank out a big paper, skip the Library and employ the excited hum of the Clough as the backdrop for your toils.
Selective listening is the key to using the garden at the top of the Clough successfully. The noise pollution that comes with being in Atlanta can be drowned out by the ambient sounds of the micro-park on the roof. Strategic placement of this space allows for a constant breeze that whistles around everyone’s ears. A high-pitched continual whistle from the wind blowing by the listener’s ears quick drowns out the busy noises of a city. An added feature to the breeze is the rustling of the leaves from the trees that are strategically placed on the top of the roof for a point of audition. The most calming sound of all, however, is the soft, yet noticeable hum of the crickets that hide in the bushes. If the listener is lucky enough to have birds in the trees, listening with intelligibility, the sound of the birds melodic calls releases the tensions of the day as the listener appreciates the simplicity of nature. The stresses of the day slowly drift away, because the distinct noises of this space lets the listener know that he is away from the hectic world around him.
When the listener needs to complete homework or study for a test, he can casually listen to the sounds of nature; the relaxing and rhythmic sounds can cause him to be more productive. While the listener won’t be completely focused on each individual sound that he hears, while he is doing homework and concentrating on a problem, he can still hear the calm sounds in the background. That allows him to instantly be brought to a state of comfort, which allows him to continue doing his work, with less stress than he had before.
