Short answer

Designers should actively manage the acoustic environment of urban parks, recognizing that specific sound pressure levels can either enhance or detract from user experience and emotional well-being.

Field: User-Centred Design
Source: Land (2024)
Method: Quantitative research with correlational analysis and model building.
Evidence: Strong effect

Designing urban parks with careful consideration of both visual elements and soundscapes, particularly by managing sound pressure levels, can significantly enhance user experience and emotional well-being. This user-centred design research insight is drawn from a 2024 study published in Land. Using Quantitative research with correlational analysis and model building., researchers explored how this design variable affects real-world outcomes. The key design takeaway: Designers should actively manage the acoustic environment of urban parks, recognizing that specific sound pressure levels can either enhance or detract from user experience and emotional well-being.

Key Findings

01Lawns, pavements, and sound pressure levels significantly impact behavioral vitality in urban parks.
02A sound pressure level of 77 dB was identified as a critical threshold for emotional perception.
03Distinct emotional prediction models can be developed for different sound pressure level zones.

Application

Design takeaway

Designers should actively manage the acoustic environment of urban parks, recognizing that specific sound pressure levels can either enhance or detract from user experience and emotional well-being.

How to apply

When designing or redesigning urban parks, measure or estimate the typical sound pressure levels in different zones and use this data to inform material choices, planting strategies, and the placement of amenities to create zones optimized for different emotional responses.

Project actions

01When researching user needs for a park or public space, include questions about sound preferences and experiences.
02Consider using sound-measuring apps or devices to gather data on existing noise levels in your design context.

Method & Evidence

AimHow do visual and auditory elements in urban parks influence user behavior and emotional responses, and can these relationships be modeled to optimize sensory design?

MethodQuantitative research with correlational analysis and model building.

ProcedureResearchers evaluated a wetland park by measuring visual perception, soundscape perception, sound source perception, and behavioral vitality. They then constructed emotional assessment models based on the quantified relationships between audiovisual characteristics, behavioral vitality, and emotional feedback.

ContextUrban park design, landscape architecture, environmental psychology.

Variables

IV["Visual elements (lawns, pavements)","Sound pressure levels","Sound source perception"]

DV["Behavioral vitality","Emotional responses"]

CV["Park type (wetland park)","Location (Chengdu's ring ecological zone)"]

Strengths & Limitations

Strengths

+Quantifies relationships between sensory inputs and user responses.
+Develops predictive models for emotional perception.

Limitations

It can be challenging to isolate the effect of sound from other environmental factors (e.g., weather, visual complexity) in a real-world park setting.

Reliability & validity

The study's validity is supported by the construction of emotional assessment models. Reliability could be enhanced by replicating the study across diverse park types and participant demographics.

Think critically

How might the ideal sound pressure level threshold differ for various types of urban spaces (e.g., a busy plaza versus a quiet garden)?

Design Principles

"Multisensory design: Integrate auditory and visual elements to create holistic and responsive user experiences."

Traditional urban park design often prioritizes visual aesthetics, neglecting the crucial role of auditory environments. Understanding how sound levels influence user emotions and behavior allows designers to create more immersive and restorative spaces that cater to a broader range of human sensory needs.

What This Means for Your Design

Parks aren't just about how they look; how they sound matters too! Too much noise can make people feel bad, but the right sounds can make them feel good. There's a 'sweet spot' for noise levels that designers should aim for.

How to use in your project

1.Reference this study when discussing the importance of considering the auditory environment in your design proposal, especially if your project involves public or outdoor spaces.

Paragraph starter

This research highlights the critical role of the auditory environment in urban park design, demonstrating that sound pressure levels significantly influence user vitality and emotional perception. Specifically, a threshold of 77 dB was identified, suggesting that designers must consider acoustic planning alongside visual aesthetics to optimize user experience and create more restorative and engaging public spaces.
