Sound Sketch

The second floor of the Gatewood Studio Arts Building is, overall designed with poor acoustic quality for an educational space. Most of the space is open with hard materials which do not absorb the sound reverberation, making the space loud and causing noise to echo throughout the entire space. The second floor is open to the first floor lobby space allowing for noise from the busy lobby area to echo throughout the second floor. The two spaces that are most acoustically sound are the lounge space and classroom 204. This is due to the use of softer materials throughout the space that provide high sound absorption. There are also acoustical panels hidden in the coffered ceiling however, the panels do not continue throughout all the coffered ceilings so they reduce very minimal sound throughout the space.

Today, acoustical panels are made of a variety of materials, textures, and colors. For example, the fabric acoustical panels located as the pin-up board on the 3^rd floor of Gatewood and also located in classroom 204 on the 2^nd floor. For the second floor of Gatewood building more pin-up fabric panels throughout the entire space would help reduce sound reverberation. Also, acoustical panels continuing throughout all the ceiling coffers would absorb noise echoing through the open lobby space. Maybe even some textured acoustical panels would be beneficial throughout the space while at the same time providing nice aesthetics because, we all are design students in this building and love nice aesthetics. Below I have provided some links to some acoustical panels provided by some well-known manufacturers.

Sound Paper 1

Places shape sounds as sound shapes places. Sound is not commonly thought of when first observing the architecture of a space but once one takes sound into consideration it is amazing to see how much sound is influenced/influences a space in relation to the type of architecture. I think, less often we use architecture to alter our sounds as people did previously. Now we manipulate sounds within spaces with acoustical panels and materials used more so than shaping a building or room to alter sound. From reading “Hearing Architecture”, is seems that architecture wasn’t originally shaped because of sounds but architecture shaped sound.

As many of us have read and experienced, the most common building material used in old Churches and buildings around was stone which is considered a hard material. Sounds reflect off of stone because hard materials do not absorb sounds just as it does not absorb light. It was really interesting to read in the article how people shaped sounds, sounds we relate to today, based off of the architecture within a building. As the article reads, “The walls were powerful instruments that people used play on.” When I was in Europe several years ago we traveled throughout Italy visiting many old churches and Cathedrals. When standing inside one of these vast churches I immediately felt in awe because of the architecture. I felt small and insignificant in the realm of this holy world. In several of the churches there was a priest reading a sermon but rather as the article says, singing, in different tones, a sermon. At the time I did not know this rhythmic way of speaking was in relation to the shape and design of the churches. I remember that the sounds that echoed throughout the church complemented the emotions felt from seeing the architecture and made me feel as if God himself was echoing throughout the space.

As people began to realize just how much they can manipulate ones experience within a building based on the architecture and shape of a building new materials were considered along with new architectural features and design shapes. The dome is a really interesting design that helps to trap and reverberate sounds throughout a located space. For example, at the Friendly Center movie theater there is a huge circular space as one enters the theater. This circular space has a huge dome overhead. This dome creates a space that when walking through when people speak their voices are echoed. This is a pretty cool feature within the theater that serves as a nice contrast to the actually theater space. This space is usually lined with cloth walls, carpet, and cloth chairs. This keeps the movie from echoing throughout the space so it is clear to hear what is going on. The carpet and other soft materials also absorb any sound made by people within the theater so the sound of the movie can be heard.

It is really interesting to see how sound and architecture correlates to give people certain experiences within spaces. Architecture serves as a good way to manipulate sounds within spaces. I believe, in previous times was more appealing the way sound was altered to give certain experiences within spaces. Now, as architecture has changed and become more contemporary, we look back at what our predecessors learned about materials, design, and sound and try to learn how we best can manipulate sound within spaces. Now we have technologies such as acoustical panels that help to direct and absorb the transfer of sound within spaces. It is interesting to see, with further research just how we can use sound and design to create experiences/ improve experiences within spaces.

Light Sketch 3: Material Observation

Light Sketch 2: Museum, Retail, Resturant

Museum Space- Lighting within this space was track lighting and spot lighting. This type of lighting is used within this space to draw people to exhibits and displays. The track lighting light up a defined path in which people are to walk and view. The spot lighting helps to draw attention to the exhibits and really visually enhance your experience when viewing.

Retail Space- The lighting used within this space are fluorescent lighting on the ceiling tiles and also track lighting throughout the space. Also, daylight floods into the space. The track lighting helps to put emphasis on items and displays. The fluorescent lighting helps to brighten up the space while the windows on the front of the store allow for warm daylight to flood in.

Restaurant Space- This restaurant has large open windows where tables are seated with track lighting above. This restaurant is located downtown Greensboro so the large windows during the day creates an environment and connect the customer with downtown. Also, at night the track lighting gives a more intimate feel. The lights are positioned to bounce of the walls and give the tables a dimmer setting. The night and day experience within this space is very different.

Observation Summary:

This window opens up to my living room and faces the South which allows for daylight to flood through the space during the day time. Early in September the sun was still higher in the sky because the autumn equinox had not occurred. During the earlier days of this sketch series you can see that the light floods into the space, lighting the floor and couch and casting shadows from objects. The shadows are longer and larger. As you flash through my sketches you can see in the days getting later into September there is less light illuminating the floor and more shadows throughout the space. Light now does not stretch across the space but is more direct and bright in areas closer to the window. Shadows become smaller and more direct behind objects (such as the lamp on the side table). On 9/30 I sketched the whole day varying around 2 hr intervals. This day you can see that when the light was the lowest in the mornings and afternoon more light flooded into the place. Shadows were cast further away from the window. When midday approached shadows became stretched but as the sun went down the shadows were smaller. The space is brighter in the afternoons than in the mornings and I think this is because the angle in which the sun hits the window as it goes down.
