The Story

I am artist who works with sound. About a year ago I thought it would be cool to make a sound piece based on the acoustics of the Tour Eiffel. Well, it is now a year later and I have just come back from my trip to Paris where I recorded the Eiffel Tower!

The organization in charge of running the Tower gave me access to the monument to document it's ambient acoustics and vibrations - the intrinsic sounds of 7300 tons of 2,500,000 rivets and 18,038 pieces of steel moving in the wind and in response to environmental changes, as well as the sonic environment of the 30,000 people who visit it daily as they move from the ground to the pinnacle. With the enormous help of the onsite consultant and Chief Technical Officer, Seth Horowitz, PhD., who headed the technical team, we succeeded in not only recorded from the publicly accessible regions, but our guide, Olivier Picard, took us to the machine room, home of the enormous 100 year old gears and motors that carry the visitors up and down the tower and the security stairwell just under the top level from which we found sound and vibrations from the elevators and the wind against the structure.

The scientific technology used to record the structure was a combination of in-ear binaural microphones and custom designed seismic microphones.  The recordings that we captured are indeed fascinating as they represent both the physical nature of the structure as well as the human experience. With these resources I have been able to documented the sound of the wind against the surfaces of the steel, the intermittent rumbles as the elevators moved up and down as well as the vibrations from people walking. With the binaural in-ear microphones I captured the ambient soundscape. One great moment was in the machine room. There I was able to record the situation when one of the elevators briefly broke down! In that segment you can hear the alarm go off and the men rushing to the scene! (Seth said I broke the Tour Eiffel!!) On the top of the tower you can hear the comments eg: holy crum!

France Languérand was able to make some exquisite photographs of the project over all and Cyril Lecomte-Languérand, made the video (I am currently waiting for rushes). Some of the images are unique because no one has ever been allowed in these areas before.

Ground level, in front of the Jules Verne Restaurant.

We recorded in two methods, one with binaural microphones. These microphones fit into the ear and capture the acoustics from the viewpoint of the person recording. The other method is with geophone microphones which record the vibrations of structures. In this case we recorded the vibrations of the elevator by placing them on the steel of the structure.

In the Machine Room

In the machine room we found the sounds of the chariot moving on the piston as it pulls the cables of the elevators and we were fortunate to capture an emergency stop of the equipment. Seth said I broke the Tour Eiffel! :-)

On the Summit and in the stairwell just below the summit.

Two recordings were done in this area. One on the Summit (right) over looking the Champs de Mars (center)and the other in the stairwell directly under the top level (left). The geophone (center) captured the vibrations created by the wind agains the structure.
