ENVIRONMENTAL COMFORT
Global comfort can be defined as a particular condition of well-being in a space (indoor or open space),
according to the sensorial perceptions determined by several factors as temperature, humidity, acoustics
and brightness.

TEMPORAL DESIGN AND SOUDNSCAPE APPROACH
In the specific context of acoustic comfort, the Temporal Design aims to create an environment on a
human scale, dominated by the laws of harmony, using a mathematical model based on processing
signals received by both the left and the right ear through operations of auto-correlation and crosscorrelation.
S = [S2 + S3]Left + [S1 + S4]Right
THESE PARAMETERS SHOWS THEIR EVIDENCE IN THE PROPOSED STUDY

TEMPORAL DESIGN AND SOUDNSCAPE APPROACH
On the other hand, the soundscape approach also allows designers to consider human perception as a
contribution. These two theories can be well integrated in the requalification of a indoor or confined
outdoor place such as urban quiet areas.

The common feature between the Temporal Design and the Soundscape Approach is precisely the
concept of "wellness" contextualized within the different phases of architectural design and urban
planning.

EU LIFE+ HUSH PROJECT
The project moves from the evidence that harmonization of noise action planning methods is needed not
only in Italy but also in all the European countries where a former Legislation about noise planning was
present at the moment of END Directive adoption.

H omogeneous action plans
THE GENERAL OBJECTIVE: harmonizing the national noise
management standards with European Directive 49/2002
to obtain homogeneous noise Action Plans, contributing
to the more general need of transposing, implementing
and enforcing a common or harmonized environmental
legislation among EU countries.

HUSH PROJECT: Don Minzoni school in Florence
The collection of subjective data has been directly used by designers, without reducing the level of
originality and creativity of the children, taking care of selecting the most appropriate materials and
solutions and taking into account the regulatory constraints for school buildings. The project for the garden
of the school combines noise mitigation goals with the needs emerged in subjective survey.

At the end, this project involved:
- the building of a non intrusive barrier, for reducing noise in a visually pleasant way, well integrated with the space and,
above all, enjoyed by the children during playtime;
- the provision of games with educational purposes;
-a wooden mobile amphitheatre to give lesson in the garden.
The location of different functions is closely related to the noise climate sub-areas of the garden.

HUSH PROJECT: area BrozziBrozzi-Quaracchi in Florence
The area of Brozzi-Quaracchi includes the historical quarters of Brozzi and Quaracchi, in the north-west of Florence.
The area is delimited by two major roads: Via Pratese and Via Pistoiese Road. This is an area with high density of
population and presence of a community deeply rooted in its territory. Noise annoyance to the population, is mainly
caused by the flow of vehicles crossing the area between the two main roads using local streets rather than the road
system outside the quarter.

Inspired by lyrics from Fabrizio De André, a famous Italian songwriter that used to mention flowers,
trees and elements of landscape in his songs and ballades
La guerra di Piero:
“Dormi sepolto in un campo di grano
tulipano
“ ...ma come tutte le più belle cose non è la rosa non è il tulipano...”
(BARLEYCORN, TULIPS)
vivesti solo un giorno
come le rose...”

La canzone di Marinella:
La canzone dell’amore perduto:
“Ricordi sbocciavan le viole
con le nostre parole...”

Un medico:
“Da bambino volevo guarire i ciliegi
quando rossi di frutti li credevo feriti...”
(CHERRIES)
5th International Symposium on Temporal Design
CONCLUSIONS
Participative design of urban areas can be a method for the acoustic
requalification of urban territory.
Global comfort should be one of the objectives of urban design
Introduction in some green areas, of pleasant sounds, like music,
composed soundscapes as a mix of natural and artificial sounds, can
make these areas more interesting and attractive for example creating a
path among flowers and music.
In some different choice of urban design the principles of Temporal
Design can be applied as far as possible.
