Noise is measured as exposure. Sound environments are lived more deeply than decibels can show: in attention, rest, bodily tension, affective-emotional tone, and the felt quality of place. Aesthetic Ecologies asks how noise, quiet, and acoustic atmosphere become part of lived environmental quality.
Environmental Noise: From Measured Exposure to Lived Exposure
The European Environment Agency’s Environmental noise in Europe 2025 report focuses on transport noise from road, rail, and aircraft. It places transport noise among Europe’s top three environmental health risks, after air pollution and temperature-related factors. Under the Environmental Noise Directive, more than one in five Europeans are exposed to harmful transport noise levels; against stricter WHO recommendations, this rises to more than 30%.
The report makes noise visible through exposure: sound pressure levels, thresholds, Lden and Lnight indicators, maps, health burdens, and policy targets. The report’s own categories — long-term high annoyance, severe sleep disturbance, highly annoyed, and chronically disturbed — already move exposure toward bodily and affective experience. Long-term exposure to transportation noise is estimated to result in nearly 17 million people experiencing high annoyance and more than 4.5 million suffering from severe sleep disturbances.
The report’s main assessment is built around long-term exposure indicators. It also notes that acute noise exposure can have immediate health consequences. Loud traffic events have been linked in studies to increased risks of cardiovascular hospitalisations and mortality, suicides, and medication intake.
For Aesthetic Ecologies, measured exposure opens onto lived exposure: the experiential dimension through which sound enters attention, rest, bodily tension, affective-emotional tone, and the felt quality of place. Sound environments are lived through intensities, durations, rhythms, interruptions, continuities, and sudden intrusions — from persistent background pressure to acute acoustic events.
Day–Evening–Night: Sound Exposure as Lived Time
The decisive issue is the threshold. END reporting thresholds are set at 55 dB for the day-evening-night period and 50 dB for the night period, while WHO recommendations are lower. The report further notes that negative health effects may occur below even the WHO recommendations, with studies indicating adverse effects from levels as low as 45 dB Lden.
The threshold is therefore not only technical. It marks a difficult translation between measurable exposure and bodily response.
The report’s own day-evening-night indicator also shows that exposure is temporal. Lden weights evening and night exposure; Lnight treats nighttime exposure separately. This matters experientially: the same sound level does not meet the same body at midday and at night. Working, resting, sleeping, recovering, attending, or withdrawing are different bodily states. Noise enters those states differently and can narrow attention, disturb rest, and change how place is felt.
The Body Under Noise
The EEA report describes environmental noise as a systemic health stressor. For Aesthetic Ecologies, this finding has experiential significance: when the body remains in arousal, vigilance, fatigue, or disrupted recovery, the medium of experience itself is altered.
This is where aesthetic vulnerability becomes relevant: under chronic acoustic pressure, exposure is not merely registered by the body; it alters the multidimensional field of experience through which rest, attention, openness, place, and relation remain available.
What appears as getting used to noise may also be a compensatory narrowing of experiential openness, while the body continues to carry exposure as stress, sleep fragmentation, or disrupted restoration. Sound environments therefore raise a future question: which bodily states, sensory capacities, and experiential qualities are being normalized under conditions of sustained acoustic pressure?
Quiet as an Experiential Condition
The EEA report gives quiet and green areas a central role in reducing noise annoyance and supporting restoration. It defines quiet areas with an explicit reference to experience: “Quiet areas can also be named as tranquil areas or calm areas as these terms relate closely to the experience of people using these areas.” Besides a “pleasant soundscape,” the report names further qualities of quiet areas: safety, cleanliness, a pleasant view, green space, and water.
For the urban-centre assessment, quiet green areas are identified as green spaces of at least 0.25 ha with road traffic noise below 55 dB Lden, accessible within a 400-metre walking distance. On this basis, only 34% of the population in the assessed urban centres can access areas that offer both green and quiet environments within this distance.

Noise and Plant Life: Beyond Human Hearing
The EEA report also points beyond human health. Environmental noise can affect biodiversity and ecosystem processes, including pollination, seed dispersal, plant reproduction, and marine habitats. It notes that increased background noise can interfere with animal orientation, predator-prey interactions, and foraging behaviour, and cites research suggesting that even aquatic plants may be affected by underwater noise. Laboratory studies on seagrass indicate changes in morphology and ultrastructure, with potential ecological consequences for seagrass meadows.
For Aesthetic Ecologies, this is decisive: noise reaches living bodies across species and forms of life. Plant bodies sharpen this point because embodiment and susceptibility begin before reflective human experience. They begin in living processes — cellular, organismic, rhythmic, sensory, and ecological. The report’s caution remains important: research is still limited. Yet the question it opens is central for sensory and aesthetic futures: sound environments may affect life at registers far outside ordinary human awareness.
Toward Sensory-Aesthetic Literacy
Silence, acoustic presence, natural sound, human activity, and noise form a living spectrum of sound environments. The decisive question is whether this spectrum still holds open the possibility of rest, attention, bodily recovery, relation, and depth.
When quiet allows experience to widen, remember, and relate, sound environments also shape environmental memory: the capacity to hold earlier acoustic-spatial atmospheres, place qualities, and remembered environmental histories as references for present orientation, self-relation, and environmental identity.
In this sense, quiet may be understood as one condition for depth: the capacity to remain with the multidimensionality of experience before it is reduced to exposure, nuisance, adaptation, or noise level. Sensory-aesthetic literacy begins where such depth can still be felt, remembered, described, and kept available for orientation.
