What we need for SoundScape and where do we need SoundScape

The investigations of the attributes describing a soundscape have become
more and more important during the last years. Since one year a
new ISO standardization working group (ISO/TC 43/SC 1/WG 54) has
started to standardize tools and methods related to the description of
soundscapes. The objective is to provide definitions, methods, measurement
and reporting requirements and to develop a common basis for
questionnaire studies.
For a technical description of a soundscape new, additional technologies
are needed such as binaural recording, psycho-acoustical analyses, simulation
and auralisation tools allowing for the prediction of perceived
sound quality. The application of adequate tools is not only considered
to analyze existing soundscapes, but also to regard these methods for
improving soundscapes of planned new places right from the beginning.

Transitions in Soundscape from Theory to Practice
G.W. Siebein

Case studies of analysis and design interventions in urban and natural
areas are used to illustrate a practical method to implement soundscape
theories in actual planning and design projects. The ambient sound
is conceptualized as a combination of specific acoustic events that can
be measured, modeled, designed and simulated in a given environment.
The specific acoustic events are used to form a taxonomy of sounds
and programs along acoustical itineraries between acoustic ”rooms” in
indoor and outdoor situations. Soundwalks are taken at multiple times of
day and night to gain a qualitative and quantitative understanding of the
rhythm and tempi of the environment. Combinations of short term detailed
acoustical measurements and calibrated recordings are made of the
specific acoustic events that comprise the ambient. Long term acoustical
measurements at fixed locations are used to define an acoustic calendar
of sounds and events. Focus group meetings with stakeholders in each
situation are used to identify specific acoustical concerns and interests.
Acoustical design palettes for urban and natural settings have been developed
to prioritize environmental intervention strategies. Sophisticated
acoustical modeling and simulations are used to present the results of
the design process to the focus groups for review and development.
