The tools we employ in quiet zone surveys and soundscape analyses include noise measurements, noise calculation models, sound sample analyses and geographical information methods. To support these, we also pool from subjective soundscape experiences and first-hand observations. To establish the values of the target group (e.g. local residents or tourists), we use questionnaires and interviews.
There are no generic or statutory criteria for defining a quiet zone. We define each quiet zone on a case-by-case basis, together with the client, local enterprises or local residents. In addition to noise levels, it is important to assess the nature of the noise (source of noise, continuity, recurrence), the kinds of sounds that support the soundscape and the kinds that clash with it. In addition to the soundscape, it makes sense to take into account the other properties of the area (intended purpose, visual landscape, other values, development projections).
We also produce proposals for protecting and developing quiet zones and for making use of them in ecotourism or as regional image-building elements and attractions.
Examples of soundscape analyses and quiet zone surveys:
- Quiet zone surveys and proposals for actions on a municipal, regional or provincial level
- Soundscape analyses and development recommendations in urban or semi-urban small-scale places of interest (e.g. parks, nature conservation areas, cultural milieus)
