Listening through a horn.

 

This is the last piece that belongs to my research on microphones and loudspeakers as musical instruments. I was invited by Jan Schacher to take part in the research project sonozones, a project that focused on the sonic characteristics of the German city Mülheim an der Ruhr. I wanted to try out what kind of effect a simple transformation would have on the sounds of the city. I tried three different concepts, a “mechanical”, “electric”, and “virtual” transformation and walked through the city with them to discover its changes in soundscape.

The “mechanical” transformation is done with horns, made from cardboard, plastic or aluminium. This transformation does not use any microphones or loudspeakers, but the horn itself is, of course, a predecessor of these devices, as I explained in chapter 1. By listening through this horn, sounds from the direction the horn is pointed at, are more clearly audible than the sounds coming from other directions. The main aspect of this performance is not in how much the soundscape itself changes, but in how our listening changes as soon as we consciously listen to something. Consequently, this becomes a performance by taking the horn and walking with the horn through the city. The audience member is, at the same time, the performer of the piece:

The soundscape of the city should be just slightly changed by the addition of a microphone and loudspeaker.

The “electric” transformation just picks up the sounds through a microphone and plays them back through headphones, while walking through the city. The soundscape of the city is slightly changed by the addition of a microphone and loudspeaker.

Listening through microphones and headphones.

 

The “virtual” transformation deliberately changes the soundscape. In the form of an iPhone App, the soundscape is picked up by the phone’s microphone, transformed with the use of live electronic processing (such as filtering and reverb), and heard through headphones.

The final presentation of this project will happen in Mülheim an der Ruhr on the 26th of October 2013.
