Noise Levels at Social Events in Kumasi, Ghana

Noise levels at social events in the Kumasi Metropolis of Ghana consistently exceed safe limits, with pubs, churches, weddings, and funerals all producing mean levels from 70 dB to over 110 dB. This data comes from a new study led by Lyndon N.A. Sackey and colleagues at Kwame Nkrumah University of Science and Technology, which measured environmental noise and surveyed public attitudes [DOI: 10.1038/s41598-026-61794-y]. The findings highlight a widespread public health concern where cultural celebration collides with hearing health.

How the Study Measured Urban Noise

To capture a complete picture of noise from social gatherings, the research team conducted measurements across five sub-metros in Kumasi: Nhyiaeso, Bantama, Subin, Manhyia North, and Manhyia South. They targeted four common types of events: church services, pubs or drinking spots, wedding receptions, and funeral ceremonies. At each location, they used sound level meters to record noise levels. The team also collected data on environmental variables, including temperature, humidity, and elevation, to see if these factors influenced how sound traveled. Alongside the physical measurements, the researchers administered surveys to local residents to assess their awareness of noise pollution, their perception of its health impacts, and their attitudes toward potential regulations.

Events Exceed Safe Limits by a Wide Margin

The results were clear and consistent. Every type of social event created noise levels that breached the Ghana Environmental Protection Agency’s (EPA) recommended daytime limit of 55 decibels for residential areas. The mean noise levels ranged from 70 dB, comparable to the sound of a vacuum cleaner, to over 110 dB, which is similar to the noise from a rock concert or a chainsaw. Pubs were identified as the most consistent sources of high noise. Churches and funerals produced variable but still highly elevated levels, often featuring sudden, loud peaks from music and public address systems.

The analysis also revealed that climate played a role. The study found a negative correlation between temperature and noise level, and a positive correlation with humidity. This suggests that on hotter or more humid days, the way sound propagates through the urban environment changes, which could affect how far disruptive noise travels into surrounding neighborhoods.

High Public Awareness Meets Cultural and Enforcement Barriers

Perhaps the most telling part of the study was the survey of public opinion. A significant majority of respondents—90.5%—stated they were aware of noise pollution and its associated health risks. An even larger portion, 94.3%, expressed support for stronger regulations to control noise from social events. This shows a community that is broadly informed and in favor of change.

However, this support for regulation exists in tension with deep-seated cultural norms. Social and religious gatherings are central to community life in Ghana, and loud music and celebration are often seen as essential elements. The researchers noted that this cultural context, combined with limited enforcement of the existing EPA standards, creates a major obstacle to practical change. People may want quieter surroundings, but not at the perceived cost of diminishing important cultural expressions.

Practical Implications for Hearing Health

Chronic exposure to noise levels above 70 dB can lead to noise-induced hearing loss, tinnitus, and hyperacusis. For individuals already living with conditions like misophonia, where specific sounds trigger intense emotional reactions, this constant background of event noise can significantly worsen stress and reduce quality of life. The study’s findings move this from a theoretical risk to a documented, ongoing exposure for urban residents.

The authors recommend a multi-faceted approach to manage the issue. They propose strengthening public education campaigns that connect cultural practices directly to health outcomes. They also suggest integrating community-based monitoring and regulation, which could be more sensitive to local context than top-down enforcement. Ultimately, enhancing the practical application of the EPA’s noise standards is necessary to translate high public awareness into tangible reductions in noise exposure.

A Model for Global Urban Hearing Health

While focused on Kumasi, this research highlights a challenge common to many rapidly urbanizing areas worldwide. Social noise is a pervasive environmental stressor with direct consequences for auditory and mental health. The link between environmental stress and hearing disorders is complex; for instance, research has explored shared pathways between PTSD and tinnitus, indicating how external stressors can affect neurological processing of sound.

Addressing noise pollution requires balancing public health with cultural integrity. The work by Sackey and colleagues provides a evidence-based starting point for this conversation, showing that the problem is measurable, the public is aware, and the need for integrated solutions is urgent.
