What is Noise Pollution?
Noise pollution is an environmental disturbance caused by loud or unwanted sounds that can disrupt harmony and comfort in society or damage the balance of the environment. Air pollution is often overlooked for the benefit of a particular group, for example, in the recent hotly debated case of "sound horeg." Unlike air or water pollution, which can be seen and measured visually, noise pollution is invisible but has very real impacts.
Sources of noise pollution can come from various human activities such as motor vehicles, industry, construction, loudspeakers, and even household activities such as high-volume television or music. Although it may seem trivial, noise pollution has serious impacts on human health and the environment.
Impacts of Noise Pollution
1. Physical and Mental Health
Long-term exposure to noise can cause permanent hearing loss, high blood pressure, sleep disturbances, stress, and an increased risk of heart disease. Continuous noise can even affect the central nervous system and hormones.
2. Disruption of Concentration and Productivity
In work or educational environments, noise can disrupt concentration, reduce productivity, and increase errors.
3. Disruption to Wildlife
Noise pollution also impacts animals, especially species that rely on sound for communication or hunting. For example, ocean noise from ships can confuse whales and dolphins.
Regulations Governing Noise Pollution in Indonesia
To control noise pollution, the Indonesian government has issued several regulations governing noise limits, noise zones, and sanctions for violations.
1. Law Number 32 of 2009 concerning Environmental Protection and Management
This law is the primary legal umbrella for environmental protection, including noise pollution. In this law, environmental pollution is defined as the entry of pollutants, such as noise, that can disrupt the balance of the ecosystem.
2. Regulation of the Minister of Environment (Permen LH) No. 48 of 1996 concerning Noise Level Standards
This regulation sets maximum noise level limits in various zones, such as:
Residential: 55 dB (daytime), 45 dB (nighttime)
Offices: 65 dB
Industry: 70–85 dB
Hospitals and schools: 45–50 dB
3. Regional Regulations (Perda)
Many regions in Indonesia have established regional regulations regarding noise. For example, DKI Jakarta has Perda No. 2 of 2005 concerning Noise Pollution Control, which regulates the use of loudspeakers in public places and their operating hours.
4. Traffic and Road Transportation Law No. 22 of 2009
Article 285 states that the use of non-standard exhausts that produce noise is subject to sanctions, including fines and vehicle impoundment.
Noise Pollution Management and Control
Although regulations exist, implementation and control in the field still face many challenges. However, several steps can be taken, and have already been taken, by the government, the community, and individuals.
1. Spatial Planning and Zoning
Industry, schools, hospitals, and housing should be separated according to noise level zones. Creating buffer zones such as parks, trees, or sound-absorbing structures is also very effective.
2. Use of Sound-Reducing Technology
Industrial and buildings in densely populated areas should be equipped with sound-reducing devices, such as acoustic walls, soundproof windows, and special ventilation systems. Public and private vehicles can also be incentivized to use sound-reducing technology.
3. Public Education and Awareness
Public awareness of the importance of maintaining the acoustic environment is still minimal. Public awareness about the effects of noise pollution and how to prevent it is crucial, such as avoiding honking indiscriminately, using standard exhaust pipes, and avoiding loud music at night.
4. Consistent Law Enforcement
Sanctions against noise regulation violators need to be consistently enforced. Without firm enforcement, regulations will become mere formalities. Operations to check noisy exhausts, restrictions on the operating hours of entertainment venues, and controls on construction projects are concrete steps that need to be strengthened.
5. The Role of Communities and Non-Governmental Organizations
NGOs and environmental communities can be driving forces for education and advocacy. They can help report violations, provide training, and encourage policy change.
Noise pollution is a form of pollution that should not be underestimated. Its impact on human health and environmental sustainability is very serious, especially in large cities with high noise levels. Although regulations exist, implementation and public awareness remain major challenges. Solutions to noise pollution require a multidisciplinary approach: clear regulations enforced by relevant authorities, supporting technology, and active community participation. With collective action and long-term commitment, we can create a quieter, healthier, and more comfortable environment for all living things.
