Short answer
When designing interventions that rely on understanding a user's acoustic environment, aim for a one-week sampling period that includes data from various days of the week and times of day, rather than focusing on specific seasons or longer durations.

A single week of continuous sound level monitoring, balanced across days and times, is sufficient to characterize an individual's acoustic environment for personalized hearing health interventions. This human factors research insight is drawn from a 2025 study published in The Journal of the Acoustical Society of America. Using Longitudinal observational study, researchers explored how this design variable affects real-world outcomes. The key design takeaway: When designing interventions that rely on understanding a user's acoustic environment, aim for a one-week sampling period that includes data from various days of the week and times of day, rather than focusing on specific seasons or longer durations.
One-week sound exposure sampling captures acoustic environment diversity for personalized interventions.

Key Findings
- 01Acoustic environment demand and diversity showed minimal variation across seasons and weeks.
- 02Significant variations in acoustic environment demand and diversity were observed between days of the week and across different times of the day.
- 03A single one-week sampling period, with balanced sampling across days and times, can adequately capture an individual's acoustic environment.
Application
Design takeaway
When designing interventions that rely on understanding a user's acoustic environment, aim for a one-week sampling period that includes data from various days of the week and times of day, rather than focusing on specific seasons or longer durations.
How to apply
When designing a wearable device that monitors environmental sound for personalized feedback or intervention, implement a data logging strategy that captures at least one full week of data, ensuring coverage across different weekdays and times of day.
Project actions
- 01When planning user research involving environmental monitoring, consider the temporal variations (daily, weekly) that might impact your findings.
- 02Justify your sampling duration and frequency based on the expected variability of the environmental factor you are measuring.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Utilized real-world data collection with body-worn dosimeters.
- +Examined sound levels across multiple temporal scales.
- +Focused on metrics relevant to intervention design.
Limitations
The study participants might have altered their behavior because they knew they were being monitored. The specific types of environments sampled might not represent all possible user contexts.
Reliability & validity
Reliability is supported by the consistent findings across different sampling periods within the week. Validity is supported by the focus on objective sound level measurements and their relevance to intervention outcomes.
Think critically
How might the findings change if the intervention was for a specific occupational noise exposure rather than general daily life?
Design Principles
"Representative sampling of user environments can be achieved efficiently by considering diurnal and weekly variations over a single, well-structured sampling period."
Understanding a user's typical sound exposure is crucial for designing effective interventions, particularly in audiology and hearing health. This research provides a practical guideline for data collection, ensuring that valuable insights can be gained without excessive or overly complex sampling strategies.
What This Means for Your Design
If you need to know about the noise levels someone is exposed to for a design project, you only need to measure it for one week. Just make sure you measure at different times on different days of that week.

Paragraph starter
The methodology for assessing user environments can be streamlined based on findings such as those by Jorgensen et al. (2025), which suggest that a single one-week sampling period, balanced across days of the week and times of day, is sufficient to characterize acoustic environments. This approach captures significant diurnal and weekly variations without the need for extended or season-spanning data collection, making it efficient for informing personalized interventions.
