I originally planned to write this post about the difference in communication between human and technological means. Specifically, I was going to look at the use of the people’s mic and police bullhorns as exemplified by the events on October 1 at the Brooklyn Bridge. While the group had been using the people’s mic to amplify communication within itself and to outsiders, the police used a single bullhorn. In a letter on behalf of the people kettled that day, lawyers argue that the bullhorn was unintelligible.
However, events at Baruch College last night changed my planned post. A clearer example of the unintelligibility of technological amplification, when compared to human-centric distributed communication, occurred in the lobby of the Baruch College William and Anita Newman Vertical Campus Conference Center on the evening of November 21.

As this video shows, the security guard attempts to use a bullhorn within the Vertical Campus lobby. Sound waves are directed only toward part of the group he is addressing. The group above on the balcony or behind him past the turnstiles must rely on sound waves bouncing off walls in order to hear his transmission. Additionally, according to the Baruch website, the lobby consists of two “stacked atria, one rising from the ground floor to the fifth floor, with a glass curtain wall facing Baruch’s Information and Technology Building to the north, across Bernard Baruch Way; another, wider atrium rising above that, from the fifth to the eighth floor,” that provide much vertical space in which sound waves can get lost while reflecting off of the eight floors of glass. Since the security guard’s attempt to use directional technological amplification based on increased volume is insufficient to communicate his message to the students, one of the students must institute a people’s mic in order to ensure that the message is understood (see 00:13 in the above video). Distributed human communication succeeds where top-down technological communication fails.


A second incident from the Board of Trustees hearing that serves as an example of the failure of technological amplification comes from the first people’s mic check within the meeting itself. As this video shows, before the chair of the meeting Valerie Lancaster Beal requests, “Security, please eliminate the young lady,” (at around 1:30) her microphone cannot make her heard above the people’s mic.
Since this is a small room—only able to hold a fraction of the public who wished to attend—the issues of technological amplification are different from the bullhorn in the lobby. In this instance, a distribution of bodies throughout the room ensures that no individual—whether a part of the people’s mic or not—is very far from another person who is repeating the message. Valerie Lancaster Beal’s microphone and amplifying speakers are placed at the front on either side of the room. Therefore, her disembodied voice appears to come from three distinct locations, whereas the people’s mic emanates from a few dozen bodies throughout the whole room. This second approach not only allows listeners to hear words as spoken by human beings—rather than relayed through electrical wires—but gives an indication of how much support there is in the room for any relayed message. Just as in distributed network computing, if one of the people’s mic speakers is “eliminated” (to use Valerie Lancaster Beal’s word choice), in theory the message could be picked up by any other member of the group, thus ensuring instantaneous redundancy backup unavailable to the single-point-of-failure electrical microphone system. If the cable breaks or power is cut to an electrical microphone system, then the ability to continue transmission is interrupted.
The benefits of the human-centric people’s mic over a technological amplification system in these circumstances—whether bullhorn or electrical microphone—seem clear and come down to a division between “many-to-many” communication and “one-at-many” top-down transmission.
With technological amplification there is merely unidirectional speaking at a group with significant opportunities for miscommunication. By contrast, the people’s mic encourages a network of one-to-one communication which allows for instantaneous dialogic communication to clarify any points that were missed.
Technological amplification passively objectifies the recipients of the message—it is unconcerned with whether or not the group agrees with the statement being transmitted. The people’s mic, however, demands active participation by all of its subjects, even if they are in disagreement. While not the ideal way the people’s mic was designed to work, the choice can always be made not to relay a message if the matter becomes too disagreeable to the participants.
The means by which distance is overcome also differs between these two methods. With technological amplification, directed volume is employed. As the message gets further away from the specific direction that speaker is facing, sound waves dissipate and the message is lost. Increasing the volume on the technological device can improve the distance at which the device can be heard, but also increases the distortion, making the message unintelligible even to the listeners close to the device. With the people’s mic, sound radiates from the speaker through the crowd of the listeners’ collected bodies. Distortion is possible, as in the children’s game of telephone. However, since the number of repeating bodies is significantly lager than the single person in the children’s game—a whole group rather than one child whispering to their neighbor—redundancy is built into the system to make distortion very unlikely. There is also a chance to clarify anything unheard or misunderstood through an immediate side conversation.
