On September 21, 2026, a study from Rollins College revealed that rocket launches at Cape Canaveral produce low-frequency sound energy that can feel louder than traditional decibel readings suggest. The research evaluated sound and vibrations from 34 rocket launches and landings within the city limits between October 2025 and May 2026.

The study utilized sensors at five locations in Cape Canaveral to gather comprehensive data on acoustic energy, structural vibrations, and outdoor air quality. Whitney Coyle, chair of the physics department at Rollins College, emphasized that conventional decibel levels do not fully capture the rumbling effects, primarily due to deep bass sounds that residents can experience but may not hear as clearly.

Among the findings, the highest peak sound pressure was recorded during the ascent of a Blue Origin New Glenn rocket. NASA's Artemis II launch also produced significant acoustic energy due to its powerful engines. Notably, the loudest moment during a Falcon Heavy mission was identified as the sonic boom from a booster landing, rather than the launch itself.

While launches were generally not perceived as excessively loud within the city, Coyle explained that the intense low-frequency sounds can cause rattling in large windows compared to smaller panes. The air quality remained within acceptable limits during all observed launches.

Looking forward, SpaceX is preparing for the 14th test flight of its 407-foot Starship, set to launch on September 28, 2026. This mission aims to send a Starship into orbit for the first time and deploy 26 Starlink satellites.

Infrastructure enhancements are underway on Florida's Space Coast to facilitate future Starship launches at Launch Complex 37 and NASA's Kennedy Space Center. An Air Force environmental impact statement has highlighted that sonic booms from Super Heavy boosters could significantly disturb residents in the area, especially at night.

To mitigate noise, SpaceX plans to employ sound suppression systems and maintain communication with the community regarding upcoming launches. In 2025, Cape Canaveral City Council approved a separate launch impact study, which was later withdrawn by the contracted university due to its limited scope. Rollins College stepped in to conduct an extensive analysis, valued at approximately $90,000, after the withdrawal.
