You can listen to a related recording “The Cafe, Mudd, 1:05pm on Monday” here.
This soundscape sample was recorded at The Cafe in Shanahan Center at Harvey Mudd College. It was around 2:35, and because many classes in the Shanahan building that began at 1:15 end at 2:30, we can expect a huge influx of people in the cafe. I was holding the recording device with its two mics facing toward the counter and people lined up.
Unlike the recording done at the same place about an hour ago (where there weren’t as many people), the background music is almost inaudible because of all the sound generated from the people around the location. Near the end of the recording, as some people move away from the location (or exit the room), the music becomes a lot more noticeable. We still hear the same steam noise and some metallic clangs which comes from either the coffee machine or other various kitchen tools. However, now all these noises are more or less blended together and less prominent that they were in the earlier recording (The Cafe, Mudd, 1:05pm on Monday). These background noises aren’t constant throughout the recording, however, and it is hard to decide whether these noises can be considered as keynote of the soundscape. On the other hand, we hear at least a couple conversations among several students pretty clearly, at least compared to the muffled conversation we hear in the earlier recording. This is mostly because the students were quite close to the recording device. Nonetheless, the Cafe was pretty crowded at the time so even if I tried picking a different spot within the room, I probably would have ended up with at least one person near me and the recording device. I consider these conversations as a signal. They are exchanging information in the form of questions and answers (“He has.” “He did?” “Did you take a picture of it?” “Do you have class?”).
