SURFACE
OBJECTIVE:
To diverge an intervention for acoustic performances, by using the development of surfaces for the design.
DESCRIPTION:
Create Surfaces that occupy a space without interrupting the existing program and maintain an area for performances.
Arch like panels transform from vertical positions to a horizontal overhead positions creating an acoustic condition in the center of the transition.
ACOUSTIC PERFORMANCE
The transforming transition made by the arching panels create an area where acoustics perform best. The transition from vertical panels to horizontal over head panels create a unique roofscape that of a concert hall. The panels begin to transform from vertical to horizontal while also acting like acoustic reflective panels helping focus sound waves to the audience. The nature of the panels at the ends of the market are used as barriers blocking unwanted sounds from outside.
SURFACE CONSTRUCTION WITH REFERENCE TO PIANO STRING DYNAMICS
Initial direction equal in both directions
Physically, the string motion can be described in the following way. As the hammer strikes the string, the string is deformed at the point of collision. The result is two waves on the string, travelling out in both directions from the striking point The wavefronts enclose a pulse, or hump, which gradually gets broader.
Direction of wave is one dimensional after wave collision
However, as the string is struck close to its termination at the agraffe, one of the wavefronts soon reaches this end and is reflected. The reflection at a rigid support makes the wave turn upside down. This inverted wave starts out to the right and restores the string displacement to its equilibrium level.
