North Avenue: NOISE – Steve Bradley

North Avenue: NOISE was sound art composition that used the windows of the Windup Space as a large tympanum, picking up the vibrations from the street and transmitting the sounds through a series of multiple FM transmitters and receivers, creating a feedback loop. Through each transmitter this low power radio piece rebroadcasted the signal to the next transmitter at 4 different frequencies over the FM dial. The final transmission was remixed into the original sound from the street windows creating a slightly off synch or “double image.” Periodically, beat frequencies emerged from the broadcast airs depending on the amplitude from the streets. The final transmission saturated the airwaves on the corner of North Avenue and Charles Street, Baltimore, Maryland, with a checkerboard pattern.
