Domenico Stanzial received his laurea
degree in Physics from the University of Ferrara,
Italy, in 1984 with a thesis on Anharmonic
Oscillators under the supervision of professor Giuliano
Schiffrer.
He was a post-graduate student at the Physics
Institute of the University
of Ferrara when, in 1986,
he joined the Italian Research Council (CNR) as a contract researcher expert in
system management and numerical optimization.
In 1988 and 1991 he attended two international
advanced courses of "Applied Digital Signal Processing" and
"Active Control of Sound and Vibration" at Purdue
University, West
Lafayette, Indiana (US) and in Denver (Colorado) with a
favorable award from the ISVR (University of Southampton,
UK) and the Department of
Aeronautics and Astronautics of M.I.T. (Cambridge,
US).
From 1991 until 2001 he was contract scientist at
the Imamoter-CNR Institute working on the development
of new applications of sound intensimetry.
He was director of the Interuniversity Centre for
Acoustics and Musical Research (CIARM) from 1998 to 2001.
Since 2001 until now is Researcher on the staff of
the Italian Research Council.
He was director of the Musical and Architectural
Acoustics Laboratory of the St. George School Foundation in Venice
(Italy)
from 2001 until 2008.
Domenico
Stanzial
contributed to various research activities and has been the person in charge of
the work for several projects funded by the European Union: RACINE-S
(IST-2001-3717) and IP-RACINE (IST-2-511316-IP) to developing new multichannel
audio technologies for digital cinema.
Since 2005 he is the scientific responsible for CNR
of the Acoustics Laboratory of the Physics Department of University of Ferrara.
Since 2008 he became a member of the teaching body
of Doctorate Program in Physics of the University of Ferrara
for the curriculum in Acoustics supervising the work of Ph.D. candidates.
The scientific activity of Domenico Stanzial is
documented with many refereed publications, patents and technical reports, and
can be framed, for the time being, in the following research lines:
1) Sound
Energetics
Domenico
Stanzial began
to develop this original branch of research since 1990 in a joint effort with
Giuliano
Schiffrer of the Physics Department
of the University
of Ferrara, following a
measurements campaign at the Ferrara Opera House based on advanced
intensimetric techniques. The research program, initially focused on the
critical review of the standard partition of sound intensity into the active
and reactive parts, came to the end with the proposal of splitting sound energy
fluxes into the radiant and oscillating parts based on the
discovery of the polarization property of sound intensity. In the
following years, this research led to the definition of a new physical concept:
the sound energy velocity based on the decomposition of air particle
acoustic velocity into two Hilbert-orthogonal components. The new concept of
energy velocity resulted in framing Linear Acoustics within the 4-dimensional
formalism of space-time so understanding the pressure of radiation as an
intrinsic property of any sound field. On this rigorous basis Domenico Stanzial
invented the "Acoustic Quadraphony" the unique physical audio
meta-format for exchanging acoustical information to recreating virtual
acoustic reality.
The last milestone of this research is the
demonstration of the tight connection existing between the mechanical
properties of energy velocity fields and the reverberation time in Acoustics.
2) Development
of advanced intensimetric techniques with applications to musical and
architectural heritage
a. Sound Intensity monitoring of organ pipes with
special attention to the phenomenon of the frequency pushing (mitnahme effekt).
b. Sound Intensity monitoring of architectural
environments (Opera Houses, St. Mark's and St. George's
Basilica in Venice, Baptistry
of St. John in the Piazza dei Miracoli
in Pisa, Conclave Room in Venice, etc.).
c. Measurement of the spatial differential properties
of energy velocity field (hyper-intensimetry) for reverberation time
evaluation.
d. Full bandwidth fine calibration of p-v
intensimetric probes by means of a progressive plane wave reference field
(acoustic wave guide of the Larix Laboratory at the
Physics Department of Ferrara University).
3) Identification,
Recording and Control of sound events for multimedia applications.
Domenico
Stanzial
studied also some problems related to the active control of sound fields by
making the field identification through the true propagator of sound field: the
4-impulse response (1 IR for pressure and 3 IRs for
air particle velocity fields). This technology has been developed and tested
within two research projects (Racine-s and IP-Racine) funded by the European
Commission in the Digital Cinema area. The playback process has been obtained
until now by means of standard multichannel configuration of loudspeakers so
demonstrating the compatibility with Dolby or DTS systems. The true
quad-playback process based on fine calibration of p-v probes is now under
development in a joint effort with the Italian Research Council at the
Acoustics Laboratory of the Physics Department of University of Ferrara.
