Measurements were taken in September, during daylight hours and on weekdays, at strategic points in this Cuban province, such as the Cuatro Caminos Roundabout, the Prado and the Boulevard, the hospital zone, parks, high-traffic avenues, and near traffic lights, according to CEAC specialist Zenaida Usagawa.

The study revealed that the average noise level was 65.6 A-weighted decibels (dBA), representing a decrease of seven dBA compared to measurements taken ten years ago.

In Marti Park, the levels do not affect people’s acoustic comfort. However, peak noise events increased by an average of 5.5 dBA, with internal combustion motorcycles and tricycles being among the main culprits.

New noise sources were also identified, linked to the growth of state and non-state commerce, as well as the use of electric generators installed on sidewalks.

During the surveys, the use of loudspeakers projected into public spaces was detected, with levels between 70 and 90 dBA, typical of work environments and capable of causing hearing loss and cardiovascular problems.

The researcher warns that, although the overall trend shows a reduction in noise pollution, prolonged and acute exposure to these noise levels constitutes a significant risk to the health and well-being of the population.

Therefore, she recommends that the use of loudspeakers and other sound sources in common areas be justified, planned, and monitored.
