- Rocket Noise: Is Space Expansion About to Boom in Your Backyard? A Conversation with Acoustic Expert Dr. Aris Thorne
Imagine your house shaking not from a passing truck, but from a rocket launching miles away. as space travel becomes increasingly frequent, the noise pollution from rocket launches and landings is emerging as a meaningful concern, demanding urgent attention and innovative solutions.
The Rising Tide of Rocket Launches
SpaceX, led by elon Musk, is launching Falcon 9 rockets at an unprecedented rate from Florida and California. Jeff Bezos’ Blue origin and other companies are also ramping up their space programs.This increased activity means more noise, and not just the roar of liftoff. The sonic booms from returning boosters are rattling windows and foundations.
The Sonic Landscape is Changing
It’s not just about the volume; it’s about the *type* of noise. These aren’t your grandfather’s occasional rocket launches. We’re talking about frequent sonic booms that can disrupt daily life. Are current noise regulations,designed for airports and concerts,sufficient to handle this new reality?
The Science of Sonic Disruption
Kent Gee, a physics and astronomy professor at Brigham Young University (BYU), is one of the few scientists studying the acoustics of space flights. He emphasizes a critical gap in our understanding: “We don’t know what people consider acceptable.” This lack of data makes it arduous to establish effective noise regulations.
Decoding the rocket’s Roar
Gee’s research delves into why Falcon 9 boosters create a unique “triple manicum” sonic boom upon returning to Earth. His team has also discovered that launch sites matter. For example, launches from Vandenberg Space Force Base in California can generate sonic booms heard over 100 miles away due to the area’s topography.
Starship: The Next Level of noise?
The Starship, SpaceX’s massive rocket designed for mars missions, is poised to be the loudest rocket ever built. SpaceX recently received approval for up to 25 annual Starship launches from its Texas Starbase, with hopes for more from Florida. this raises serious concerns about the potential impact on nearby communities.
Monitoring the Soundscape
Cabo Canaveral, Florida, has already hired scientists to monitor sound levels, vibrations, and air quality during launches. This data will serve as a baseline for future Starship launches, helping to assess their environmental impact.
The BYU Research Team: On the Front Lines of Sound
gee and his team are meticulously recording and analyzing rocket noise. Their equipment, deployed near launch sites, captures a wide range of frequencies, including those below human hearing. They collect data at an remarkable rate of over 100,000 times per second.
Unraveling the Mysteries of Sonic Booms
BYU physicist Grant Hart emphasizes the difficulty of accurately recording rocket noise. The team’s research has debunked myths, such as the claim that saturn V rockets melted concrete. They estimated Saturn V generated 203 decibels,which would heat the air by only 4 degrees Celsius – not enough to melt concrete.
Community Impact: Shock Waves and car Alarms
During a Starship test flight, shock waves triggered car alarms in South Padre Island, Texas. Student Noah Pulsipher, who witnessed multiple launches, noted that the noise levels varied significantly. These anecdotal observations highlight the unpredictable nature of rocket noise and its potential to disrupt daily life.
The Crackling Sound of Space
Gee explains that the “crackling” sound frequently enough heard during rocket launches is caused by different parts of the sound wave traveling at varying speeds. This phenomenon occurs because the intense sound compresses and heats air molecules, causing them to accelerate, then slow down as the air expands and cools.
The Future of Rocket Noise: A Call to Action
as Starship launches potentially increase in Florida, communities like Titusville and Cocoa Beach could face significant noise impacts. Gee stresses the importance of data and conversation: “We are here to provide data and comparisons, and I feel it helps to create a conversation.”
balancing Progress and Preservation
the challenge lies in balancing the advancement of space exploration with the need to protect communities from excessive noise pollution. Early action is crucial. As Gee warns, “If we wait ten years, it will be too late.”
What Can Be Done?
Potential Solutions
Several strategies can be implemented to mitigate rocket noise:
- Quieter Rocket Designs: Similar to advancements in aircraft noise reduction,future rocket designs can incorporate technologies to minimize sonic booms and overall noise levels.
- Launch Scheduling: Adjusting launch times to minimize disruption during sensitive hours (e.g., nighttime) can definitely help reduce community impact.
- Noise Barriers: Constructing physical barriers around launch sites can help deflect and absorb sound waves,reducing their reach.
- Community Engagement: Open communication and collaboration with affected communities can foster understanding and support for space programs.
The future of space exploration hinges on our ability to address the challenges of rocket noise. By investing in research, implementing mitigation strategies, and fostering open dialog, we can ensure that the benefits of space travel are shared by all, without compromising the quality of life for those living near launch sites.

Time.news: Welcome, Dr. Thorne. space exploration is booming, but so is the noise. Our recent article highlighted the growing concern about rocket noise and its impact on communities. Can you give us a brief overview of the problem?
Dr.Aris Thorne: Absolutely. we’re entering an era of frequent space launches, and with that comes a notable increase in noise pollution, especially from sonic booms generated by returning boosters and the sheer roar of liftoff. We’re not talking about the occasional rocket launch anymore; we’re looking at perhaps disruptive, repeated sonic booms that can rattle homes and disturb daily life.
Time.news: The article mentioned SpaceX’s Starship and its potential for intense noise levels. What makes Starship concerning from an acoustic perspective?
Dr. Aris Thorne: Starship is, simply put, massive. Its sheer size and the power required for launch translate to an unprecedented amount of noise. The article rightfully points out that even a test flight generated significant sonic booms felt kilometers away. Increased Starship launches, as planned by SpaceX from Texas and possibly Florida, pose a real risk of dramatically increasing noise exposure for nearby communities.
Time.news: The article also referenced Professor Kent Gee and his team at BYU. Their research seems crucial. What’s so important about understanding the science behind rocket noise?
Dr. Aris Thorne: Professor Kent Gee’s work at Brigham Young University (BYU) is invaluable. We need a complete understanding of the acoustic research behind rocket noise to effectively mitigate its impact. His team is meticulously documenting the sound profiles of these launches, even capturing frequencies below what humans can hear.
