A Framework of Soundscape Design Potentials
J. Kang
University of Sheffield, School of Architecture
Whilst much work has been carried out in terms of soundscape description
and evaluation, it is important to put soundscape into the intentional
design process comparable to landscape, and to introduce the theories
of soundscape into the design process. In this paper a framework of soundscape
design potentials is explored by considering four key factors,
namely sound sources, space, environment and people, with a particular
attention to urban open public spaces. In terms of sound sources, both
active and passive sounds are discussed, relating to the sounds from
the activities of users such as group dancing, and the sounds from the
landscape elements such as fountains, respectively. Designable factors
include sound level, spectrum, as well as temporal and spatial dynamic
process. In terms of spaces, effects of architectural changes and urban
design options on the sound field are studied based on parametric
studies using a series of computer simulation. In terms of environment,
multi-sensory interactions are discussed. In terms of people, since different
users may have rather different soundscape preferences, a space
should be designed accordingly.

Soundscape Approach in Urban Renewal: Parks and Areas of
Acoustic Quality
L. Maffei

Although considerable efforts in the application of noise control policies
and techniques, the noise in urban sites is not decreasing and, in some
cases, a resignation feeling towards noise annoyance is growing among
population and city management. The Soundscape approach, which emphasis
the role of sound in the perceived environment and involves more
actors and disciplines, can overturn this tendency complementing the
noise control engineering and acting more effectively in the urban space
design processes. In this paper is presented a new interdisciplinary approach
applied to the historical centre of the city of Naples (Italy) which,
as Unesco Patrimony, will be during the next years under a complex
urban renewal project. The approach, connecting cultural heritage disciplines,
visual and audio perceptions and studies on local population’s
and tourists’ attitude and expectations , has permitted the identification
of urban areas which already have the potentiality of ”restoration parks”
and/or ”areas of acoustic quality” or that can achieve easily this classification.
Immersive audio-visual virtual reality tools have been used to
validate new projects of urban design in these areas.
