From Local Interfaces to Global Challenges: Auditing Digital Noise on University Websites in Poland

University website research to date tends to focus on conformity with technical standards. It rarely analyses the systemic nature of digital noise and its cognitive impacts. The study measures the intensity of digital noise on public websites of Polish universities (n = 65) and identifies its most common sources. The author investigates five dimensions: Distraction Intensity, Content Overload, Readability, Visual Balance, and Signal-to-Noise Ratio. The results are aggregated into a synthetic Noise Level Score (NLS) and analysed statistically. Four categories of digital noise have emerged from the observations: obligatory, compensated, ornamental, and habitual. This categorisation indicates that digital noise is not always random. It can be a supervised or even intentionally designed phenomenon when specific elements (such as disclaimers, system alerts, or consent layers) are not only expected but required by the user or the law. The study reveals a highly homogeneous sample and strong convergence of the results, indicating a systemic problem. Over 47% of the websites exhibited high NLS, while only 9% scored low. This means that content, visual, and interaction overloads are not incidental. Instead, it follows from the institutional and technological constraints on Polish higher education. The results ought to be interpreted in the context of the institutional communication imperative, defined as a constant pressure from legal obligations, standards, PR, market, and organisational factors towards constant publishing for multiple audiences through multiple channels.
