What is a soundscape intervention?
The term “soundscape”, as it has been established in the area of acoustic ecology, characterizes “acoustic environment as perceived or experienced and/or understood by a person or people, in context”.1 A soundscape intervention is a site-specific design to preserve or improve a soundscape. There is a broad variety of interventions conceivable to design soundscapes, ranging from micro-scale actions in specific locations like a park, to interventions on a large-scale, referring to a whole city quarter. Soundscape interventions are related among other things to a reduction of unwanted noise, to the introduction of pleasant sounds for masking purposes or to the preservation of soundmarks that embody a local identity.
What makes a soundscape intervention unique from a noise control measure is that it goes beyond reducing noise levels, to instead promoting or improving the quality of a soundscape as a whole. At the end, a combination of different types of soundscape interventions are frequently applied to achieve a significant impact on residents and soundscape visitors.

SEA ORGAN IN ZADAR, CROATIA
The sea organ in Zadar, Croatia was implemented in April 2005. Promoted by local authorities and businesses, it is a permanent installation, attracting residents and tourists on a regular basis.
In the audio example you can hear the sounds created by the pipes of the Sea Organ.
This mechanical installation with musical features is built into the seaside promenade. The sea waves drive air into a system of pipes similar to a mouth harp, producing the never-ending exchange of C major and G major chords. The project was conceived within the wider effort to revitalise the neglected part of the historical city centre, next to the new cruise ships pear on the top of the peninsula. Noise complaints from the nearby residential building apparently have no influence on the management of the installation.
