Since 1996,\u00a0 International Noise Awareness Day\u00a0<\/a><\/strong> is commemorated on the last Wednesday of April. This global campaign aims to raise awareness of noise on the welfare and health of people.\u00a0 People are called upon to take part in a series of events with emphasis on protection of the acoustic environment and hearing,\u00a0 raising awareness on the annoyances and damages produced by noise, and educating on measures to avoid this harm to human health and well-being<\/strong>.<\/p>\n

According to the World Health Organization (WHO)<\/strong>, the harmful effects of noise<\/strong> begin to manifest themselves when we are exposed to levels above \u200b 65 dB. The greater the sound level, the more difficult it becomes to concentrate. If noise levels persist and increase, people exhibit stress, irritability and fatigue. Furthermore, exposure to more than 100 dB has a direct temporary effect on hearing<\/strong>. The severity of these effects are significantly greater with longer exposure time. For example, an overexposure above 65 dB causes deafness, stress, hypertension, heart problems and insomnia.<\/strong>
