Physics Professor Discusses Rocket Launch Noise Research

Unlike standard commercial aircraft noise, heavy-lift rocket launches generate powerful, low-frequency sound energy that travels over vast distances. These low-frequency waves interact directly with residential structures, causing rumblings and physical vibrations in nearby homes and buildings. Traditional noise metrics used by the Federal Aviation Administration were originally established for overhead aircraft flight paths and fail to capture the distinct low-frequency acoustic profile produced by modern rockets.

To measure these complex acoustic dynamics, Coyle collaborates with undergraduate physics students at Rollins College. The research team deploys specialized instruments—including calibrated sound level meters, accelerometers, and ground vibration sensors—to collect comprehensive data. Their instruments measure both audible sound levels and imperceptible low-frequency components, evaluating specifically how structural elements such as windows and walls respond to launch energy.

Although residents along Florida’s Space Coast remain highly supportive of space exploration and local industry growth, community planners and regional agencies currently lack sufficient empirical data to evaluate the long-term impact of frequent launches. Coyle’s work seeks to fill this data gap by establishing a baseline for rocket-specific acoustic environments.

Ultimately, the research aims to help planners better understand structural responses in nearby buildings and determine how residents perceive and respond to launch noise over time. As global access to space rapidly expands, establishing a detailed understanding of these environmental and community factors will become essential for sustainable spaceport operations.
