As a researcher in landscape architecture, I have mostly been in contact with noise in relation to the planning and design of outdoor environments. In this context, noise is generally regarded as an unwanted disturbance, exposure to which is measured in sound pressure levels (EU 2002) and associated with adverse negative health effects, like stress, hypertension and cardiovascular disease (WHO 2018). The most established means to deal with noise is through environmental noise management, which largely relies on a quantitative understanding of sound (Brown 2010; Bild et al. 2016). In my research, I have sought to expand environmental noise management by adding qualitative perspectives that better comply with established design processes used in landscape architecture. In my doctoral thesis (Cerwén 2017), I proposed ‘soundscape actions’ as a tool for landscape architects and urban designers to consider in noise-exposed situations (see also Cerwén et al. 2017; Cerwén 2019, 2020). Based on three main categories (localisation of functions, reduction of unwanted sounds and introduction of wanted sounds), the tool merges knowledge from several fields. For future work, I have identified five noise challenges that I find significant for research relating to the planning and design of outdoor environments.
