Why is noise pollution a problem that needs solving?

The soundscape of urban life is an unseen threat that – depending on individual living and work circumstances – comes at us from all sides: The neighbours next door, underground trains, construction, aircraft, and many traffic sounds from honking cars to wailing sirens. Various studies on noise pollution show:

• 64% correlation between loss of hearing and noise pollution, according to the Worldwide Hearing Index.
• People living in the loudest cities have the hearing capabilities of someone 10-20 years older.
• Long-term exposure to day-evening-night traffic noise levels affects an estimated 113 million Europeans.
• Mental health effects include an increased sensitivity to stress, intensified irritability and frustration, anxiety, and a significant impact on people’s mood and ability to concentrate due to a reduced depth and quality of sleep.
• Other than Noise Induced Hearing Loss (NIHL), harmful noise exposure can exacerbate cardiovascular disease, type 2 diabetes, memory impairment, and low birth weight.

The impact of noise pollution is equally dire for animal species that depend on sound for survival – to navigate during migration, defend their territory, communicate underwater, or find a mate. In cities, noise pollution affects animals as profoundly as it does humans:

• Communication disruption: Acoustic pollution interferes with mating calls, warning signals, and the ability to navigate.
• Stress and behavioural changes: Continued exposure to chronic noise can lead to changes in behaviour, such as increased aggression, reduced feeding, and altered migration patterns.
• Impact on predator-prey relationships: Noise makes it harder for predators to hunt and for prey to detect and avoid predators. This can lead to ecosystem imbalances and affect certain species’ survival rates.
• Habitat avoidance, e.g., birds abandoning nesting sites, leads to reduced breeding success and population decline.

Away from urban spaces, ships, oil drills, sonar devices, pleasure cruises, and seismic devices have made the once tranquil marine environment loud and chaotic. For sound-sensitive animals like dolphins and whales, this is particularly problematic:

• Consistent sonic disruption interferes with echolocation that marine mammals depend on to communicate, navigate, coordinate hunts, find each other, and warn others about predators.
• Causes heightened stress responses, contributing to population decline.
• High-intensity and loud sounds underwater (e.g., military sonar and seismic air guns) send animals into a panic, causing them to ascend too quickly, resulting in decompression sickness, lesions and skin damage, hearing loss, and even death.
• It drives them out of important feeding or breeding grounds and forces them to change migration routes, putting them at risk of getting trapped in unfamiliar territory (e.g., ice floats) and encountering new predators.
• Forces some species to use a higher pitch to be heard above the noise. These new vocalisations make it harder for members of the same pod/species to recognise each other and find mates.

What noise reduction solutions can IoT technologies provide?

The Internet of Things (IoT) refers to a network of “smart” devices that communicate and share data over the internet. Devices like sensors and monitors collect information (e.g., peak decibel readings) and respond to specific conditions in real time, making them highly effective for managing noise pollution. By continuously tracking noise levels, IoT-powered noise reduction solutions can help reduce the harmful effects of excess noise on human health and the environment.

Urban Noise Monitoring Networks

IoT-enabled sensors can be deployed across cities to monitor noise levels continuously. This data helps identify noise hotspots, guiding regulatory actions, urban planning, and zoning to reduce public exposure to harmful noise.

Example Solution: An IoT network that identifies peak noise areas in a city, enabling municipal authorities to take action, such as introducing quieter public transport options, making informed decisions on placing green spaces where they’re most needed, adjusting traffic patterns, and creating more pedestrian-friendly zones with less noise.

Smart Barriers and Noise-Canceling Technologies

Noise-canceling IoT technologies actively reduce noise levels in designated areas, creating quieter urban spaces for people and animals alike. Intelligent barriers equipped with noise-cancelling devices can adapt in real-time based on sensor noise data.

Case Study: REEDuce, an Austrian startup, designs ecological barriers to reduce noise pollution from roads and other sources. It constructs these barriers using renewable materials like reed, thermowood, and clay. These components mitigate noise and contribute positively to the environment by acting as carbon sinks and promoting air quality. This product caters to the need for noise barriers in residential areas near busy roads or highways and industrial sites.

Marine Acoustic Monitoring and Deterrent Systems

IoT sensors and acoustic deterrent devices (ADD) can monitor and control underwater noise, helping reduce harmful exposure for marine wildlife. These systems can alert ships to reduce speeds in sensitive areas or use deterrents to guide wildlife away from high-traffic zones gently.

Example Solution: An IoT system that tracks marine noise levels near a coral reef triggers automated alerts for vessels to reduce their speed or reroute. In addition, ADD can be used to discourage marine mammals from approaching an area where anthropogenic noise (e.g., drilling) could cause auditory damage or result in getting caught in fishing nets.

Smart Windows with Noise Reduction Capabilities

Some smart windows now come equipped with noise-cancelling technology that actively reduces external noise entering a home or office. These windows can detect noise frequencies from outside, like traffic or construction sounds, and counteract them with sound waves, creating a quieter indoor environment.

Example Solution: An intelligent window system that uses IoT sensors to detect external noise levels and automatically activates noise-cancelling technology to reduce disruptive sounds, ideal for urban apartments or home offices.

Wearable Noise Reduction Devices

Wearable IoT devices, designed as small earpieces or around-neck devices, can offer selective noise-cancelling features without covering the entire ear. They are particularly useful for individuals who need to stay aware of certain sounds (e.g., conversations or cars) but want to minimise other background noise.

Example Solution: A wearable noise reduction device that automatically adjusts noise cancellation based on location and time of day is perfect for open-office spaces or people on the go who want flexibility in their noise environment.

Smart Home Noise Monitoring and Control Systems

IoT-enabled noise monitors work within smart home systems to detect and reduce ambient noise in shared spaces. These systems can be programmed to send alerts when noise exceeds a set threshold, allowing homeowners to respond proactively (e.g., turning down music or managing noise sources). Additionally, they can work with other smart devices, like sound-absorbing panels, to actively reduce sound.

Example Solution: A home monitoring system that alerts parents if children’s rooms get too loud or activate sound-absorbing panels in shared spaces to ensure a quiet environment.
