Singing dunes is a phenomenon found exclusively in desert
environments. "The sounds are produced when grains drum against one
another; exciting elastic waves on the dune surface of the sand bed acts
like the membrane of a loudspeaker.”The sounds resemble the beating of a
drum or the noise of a low-flying jet. They can be heard up to 10 km
away.
The skyscraper was designed by Barbara Leonardi and Oliver Dibrova as part of Hani Rashid
Studio. The main inspiration was found in a phenomenon of singing
dunes. Hypothetically located in Dubai, the project is a hybrid space,
with diverse surfaces representing different programmatic conditions. A spiraled structure continues the public space and contains four plugged in hotel-units,
which can act independent from each other and are specialized on
diverse topics (business hotel, recreation hotel, sports hotel and city
hotel).
The final configuration of the building is set upon through an
experiment: a plate or drum is forced to vibrate historically with a
violin bow or with a speaker. A fine sand or powder is sprinkled on the
surface and allowed to settle. It sets at those non-vibrating parts of
the surface, namely the nodes of vibration. Using an equation for the
zeros of standing wave on square plate, different sound-files are
extracted and used as input. They’re translated into frequency and
amplitude, eventually generating a 3d structure.
