Resumo
O artigo aborda a problemática do ruído indesejado e seus efeitos negativos na qualidade de vida das pessoas. O ruído pode ser considerado uma forma de poluição sonora e pode ser gerado por várias fontes, como tráfego, construções e atividades humanas. O texto menciona diferentes tipos de ruído, incluindo contínuo, intermitente, impulsivo e de fundo. A exposição constante ao ruído pode causar danos à audição, além de perturbação, desconforto, prejuízo cognitivo, distúrbios do sono e doenças cardiovasculares. De acordo com dados da Associação Brasileira para a Qualidade Acústica, cerca de 10% da população mundial está exposta a níveis de ruído prejudiciais. A Organização Mundial da Saúde (OMS) destaca que a poluição sonora é o segundo maior agente poluidor ambiental, após a poluição do ar, e prevê um aumento na perda auditiva até 2050. O artigo menciona que medidas de controle de ruído são necessárias em diferentes níveis, desde o uso de protetores auriculares em nível individual até o estabelecimento de normas e regulamentos para limitar os níveis de ruído em atividades industriais, veículos e construções em nível comunitário. No contexto de ambientes internos, como salas de aula, hospitais e espaços de relaxamento, é importante garantir um nível adequado de silêncio ou baixo ruído para que as atividades sejam eficientes, seguras e propícias ao relaxamento. O artigo propõe uma solução de baixo custo baseada em um hardware projetado, programado e desenvolvido para monitorar em tempo real o nível de intensidade sonora no ambiente, e quando forem ultrapassados os limiares pré-estabelecidos por normas locais, geram-se sinais de alerta ou mecanismos de controle afim de contribuir com o protocolo de silêncio local. A metodologia utilizada no artigo inclui uma pesquisa bibliográfica para embasar teoricamente o tema do ruído e seus impactos, bem como normas técnicas e regulamentadoras. Além disso, houve a formulação do problema a ser abordado e a proposta de prototipagem como solução. A partir desse cenário, objetiva-se com esta pesquisa fornecer uma alternativa de baixo custo para o controle de ruídos indesejados em ambientes fechados, visando o bem-estar físico e psicológico das pessoas expostas diariamente a esses ambientes.
The article addresses the issue of unwanted noise and its negative effects on people's quality of life. Noise can be considered a form of sound pollution and can be generated by various sources such as traffic, construction, and human activities. The text mentions different types of noise, including continuous, intermittent, impulsive, and background noise. Constant exposure to noise can cause hearing damage as well as disturbance, discomfort, cognitive impairment, sleep disorders, and cardiovascular diseases. According to data from the Brazilian Association for Acoustic Quality, approximately 10% of the world's population is exposed to harmful noise levels. The World Health Organization (WHO) highlights that noise pollution is the second-largest environmental pollutant after air pollution and predicts an increase in hearing loss by 2050. The article mentions that noise control measures are necessary at different levels, from using ear protectors at an individual level to establishing standards and regulations to limit noise levels in industrial activities, vehicles, and community constructions. In the context of indoor environments such as classrooms, hospitals, and relaxation spaces, it is important to ensure an adequate level of silence or low noise for efficient, safe, and relaxing activities. The article proposes a low-cost solution based on a hardware designed, programmed, and developed to monitor real-time sound intensity levels in the environment. When the 2 pre-established thresholds set by local regulations are exceeded, alert signals or control mechanisms are generated to contribute to the local silence protocol. The methodology used in the article includes a literature review to theoretically support the topic of noise and its impacts, as well as technical and regulatory standards. Additionally, the problem to be addressed was formulated, and prototyping was proposed as a solution. Based on this scenario, the objective of this research is to provide a low-cost alternative for the control of unwanted noise in enclosed environments, aiming at the physical and psychological well-being of people exposed to these environments on a daily basis.
