Noise Cameras Quietly Expand Across US Cities to Curb Loud Vehicles

Noise cameras, a technology that combines microphones with cameras and software to pinpoint loud vehicles, are increasingly being deployed in cities across the United States. At least 10 jurisdictions have implemented or piloted these systems in recent years, with more communities considering similar programs. These cameras aim to address issues ranging from excessive engine and muffler noise to loud music and exhaust braking from trucks.

New York City has one of the more established enforcement programs. In 2025, its Department of Environmental Protection operated 12 cameras that recorded nearly 16,000 noise events and resulted in over 1,600 summonses. Penalties in New York can be substantial, with muffler violations carrying a minimum fine of $800 and a maximum of $2,625. The system used in New York is the SoundVue system from Intelligent Instruments Ltd., a UK-based company.

Intelligent Instruments' technology is also being used in other cities. Knoxville, Tennessee, has utilized the SoundVue system in a mobile noise camera program, though it currently issues warnings rather than automated citations. Miami Beach, Florida, tested the technology but was restricted by state law from issuing automated citations. The city has since shifted to a pilot program involving police officers.

Smaller communities are also adopting the technology. Avoca, Iowa, implemented a noise camera program along Highway 59 to address complaints about loud engine-compression braking from trucks. During a one-month pilot, the system recorded 183 violations involving 83 vehicles.

Some states are using noise cameras for data collection rather than immediate ticketing. Hawaii launched a two-year pilot program on Oʻahu to gather information on vehicle noise levels, which it plans to use to inform future legislation. Similarly, Kirkland, Washington, tested noise cameras to assess the system's ability to reliably identify specific noisy vehicles in traffic, without issuing citations.

Another key player in the market is Sorama, a Dutch company whose technology visualizes sound sources. Newport, Rhode Island, uses Sorama's mobile equipment and has reportedly begun issuing $250 citations for excessive noise. Albuquerque, New Mexico, conducted a six-month pilot program with Sorama cameras to collect noise data.

Santa Fe, New Mexico, has entered into a five-year contract with Jenoptik Smart Mobility Solutions for automated speed and noise enforcement. The city planned to use mobile enforcement devices, with a warning period before issuing citations.

Maryland has also seen the deployment of noise cameras, with University Park activating one in January 2026 as part of a county and state effort. West Haven, Connecticut, is preparing to install four noise-detection devices, with state law setting a threshold of 80 decibels for violations and a penalty structure that includes warnings and fines.

Discussions about noise camera programs are also underway in larger cities. Boston City Council approved a request to explore such a program in response to complaints about loud cars and street takeovers. Providence, Rhode Island, has issued a request for proposals for an acoustic-camera pilot program.

The accuracy of these systems can be a challenge. The California Highway Patrol evaluated systems from multiple vendors, including Intelligent Instruments, and found that while the technology could detect excessive exhaust noise, the evaluated systems were not always adequate as standalone enforcement tools. Factors like lighting, license plate visibility, and traffic conditions can affect evidence reliability, underscoring the importance of human review in many programs.

Privacy concerns are also a consideration, as these systems often capture license plate information. While some systems are designed to avoid recording vehicle interiors, the data collected and its retention policies vary by jurisdiction. As these cameras become more common, drivers are advised to understand what information is recorded and how it is used in their local areas.
