Last night, after the last faculty and staff had left the building, Mike Wittgraf and I also with two graduate students set up some speakers and recording equipment in Merrifield Hall in the University of North Dakota’s campus to see whether we could capture some of the building’s distinctive sound.
This project is a bit of a passion project for me. I started my career at UND in Merrifield Hall and spent many happy hours in the North Dakota Quarterly office and my various academic office’s in the building. As part of that, I often found myself immersed in the building’s distinctive soundscape. From the reverberation of footsteps down it’s long, terrazzo paved hallways to the whirring and clunking of the building’s various pumps and lifters, the building’s sounds have long offered a kind of familiar backdrop to late nights and early mornings on campus.
Next year, the building will undergo some serious (and much needed) renovations and I suspect some of the characteristics that made it so endearing to me will be lost. My students in a my English graduate class on things have likewise recognized that Merrifield’s century old design and layout will give way to something more contemporary. They are working on a series of papers that consider the history and, perhaps more importantly, the feeling and experience of Merrifield Hall.
Our efforts to record the sound of the building are part of this larger effort. Last night began by running a series of long tones from a 1000 watt JBL subwoofer.
It has just enough power for us to discover that a tone of 44 hz would produce a standing wave in Merrifield’s basement hallway. We could walk through the wave and find nodes where it was almost inaudible and then walk a few feet further and find places where the sound was almost deafening. These tone tests also revealed when various features of the building would resonate with various frequencies and rattle windows in offices. You can hear some of those moments at the end of the video above.
We then set up a pair of powered fuller-range speakers to complement the subwoofer and to play with a wider range of frequencies.
We marveled at the how clearly we could hear the notes linger and decay in the hallway. At times we could literally hear the pulse tone racing back and forth up and down the long corridor. For me, these reverberations echoed some of the sounds I remembered fondly from my time in Merrifield and I got pretty exciting that we were not only producing new kind of sonic situations (poetry?) in the building, but that it was also so deeply rooted in my own experiences there.
Finally, we set up a microphone on the fourth floor landing at the opposite corner of the building from our speakers. There’s a lot of a concrete, steel, brick and glass between the speakers and the microphone, but we hoped that we could not only record the time that the sound too to traverse the building, but also show how the building itself amplified, distorted, and conjured sounds through its fabric.
We connected this microphone to a laptop which could be time synced with the computer responsible for producing the sounds. This should allow us to measure the time it takes for sound to traverse the building. We also anticipate that it’ll create some interesting sonic features as the microphone also captured the various background sounds that are so characteristic of Merrifield Hall.
The end result of this work is a bit hard to know right now and I suspect we’ll come back over the summer to do more recording and play around with how things sound, but we have a start.
