hEAR is an experimental headset that integrates binaural microphones and stereo headphones into a pair of sound isolating ear muffs. As a platform for acoustic sensorial intervention, hEAR provides the means to manipulate how an environment is heard. As such, the headset can be used to formulate and test research questions involving how hearing impacts one’s relationship to an environment.
This first iteration of hEAR was developed during an undergraduate degree in Computation Arts at Concordia University in Montréal, Canada. The software application Max by Cycling ’74 was used to experiment with signal processing techniques including audio delay, pitch shift, and spatialization. The results were profound with respect to the ability to maniuplate, control, and shift an individual’s perception of their environment.
hEAR was installed as part of a residency in Concordia’s Black Box, P.A.R.E., which was hosted by the Topological Media Lab. A control surface was developed using Mira, an iOS controller for Max MSP, providing other researchers with the ability to experiment with the potential of the headset.
