If you live near Cape Canaveral and swear rocket launches rattle your windows more than any noise meter seems to justify, science is now on your side. Researchers from Rollins College in Winter Park set up acoustic sensors at five locations inside Cape Canaveral city limits and tracked 34 launches and booster landings between October 2025 and May 2026 — producing an 85-page report that confirms what residents have long sensed: standard decibel readings miss a big part of the picture.
Physics department chair Whitney Coyle explained that most of a launch's acoustic energy sits in deep, low-frequency bass that human ears barely register on a traditional scale. On paper, a SpaceX Falcon 9 launch reads about as loud as a normal conversation, and a Blue Origin New Glenn rocket is comparable to a busy road. In practice, that low-end energy travels straight through walls and sets large sliding-glass doors rattling far more than smaller windowpanes. Air-quality particulate levels stayed within federal limits throughout the study period, and no structural damage assessments were made.
A few specific launches stood out in the data. New Glenn produced the highest peak sound-pressure level during ascent, while NASA's Artemis II registered notable total acoustic energy despite launching from Kennedy Space Center's pad 39B — a full 16.8 miles from Cape Canaveral City Hall. The single loudest acoustic spike in the entire dataset came not from a liftoff at all, but from a sonic boom generated by a descending SpaceX Falcon Heavy side booster touching down after launch.
The timing of the study is deliberate. SpaceX is actively building Starship infrastructure at both Launch Complex 37 at Cape Canaveral Space Force Station and pad 39A at Kennedy Space Center. A federal environmental impact statement already determined that sonic booms from descending Super Heavy boosters will create "significant impact" on community annoyance across Cape Canaveral, Cocoa Beach, Titusville, and Merritt Island — and predicted nighttime booms from LC-37 missions could wake roughly 54% of sleeping residents on average. Cape Canaveral City Hall commissioned the Rollins study to establish an independent acoustic baseline before those larger rockets begin flying locally, a step officials say is rare among launch-adjacent communities.
The city paid $13,000 for the research; Rollins College estimated that in-kind personnel and resources brought the project's total value close to $90,000. The full reports and raw data are posted on the Cape Canaveral City Hall website under the Safety section. No decision has yet been made on whether the data-collection program will continue.
