We silence the future of air mobility.
We want drones to coexist with cities: less noise, more social trust. We do for drones what active noise cancellation did for headphones: reduce perceived annoyance without stopping the music of innovation.
The idea that drives us
The urban sky will only be useful if it is habitable. Progress is not only measured in kilometers per hour, but in the quality of sound it leaves behind. Noise is not an unavoidable byproduct: it is a design, perception, and cultural challenge. Our purpose is to help drones sound like neighbors and service, not like an invasion.
Sound vs. Noise
Sound is information; noise is friction. In the city, the how and when matter just as much as the how much. Designing with this reality in mind changes the outcome.
Sensitive Environments
Hospitals, schools, residential areas, and heritage sites require specific criteria for acoustic coexistence and community communication.
Time and Acceptance
Less noise equals more time windows and agile permits. Social license and technical license walk hand in hand.
Acoustic Consulting for Drone Operations
We support administrations, vertiport managers, and operators in designing operations that are socially acceptable from an acoustic perspective.
Environment Diagnostics
- Acoustic sensitivity map by neighborhood and land use.
- Identification of time windows and constraints.
- Local regulatory review and institutional coordination.
- Social acceptance requirements document.
Route and Schedule Design
- Corridors and altitudes that are friendlier to the city.
- Scheduling that reduces perceived annoyance.
- Best practices for responsible acoustic operation.
- Technical justification for permits and public communication.
Pilots and Community Listening
- Field tests with clear methodology.
- Neighbor feedback channels and workshops with local stakeholders.
- Measurement and reporting before/during/after the pilot.
- Mitigation plan and success criteria.
Monitoring and Continuous Improvement
- Dashboards with perception indicators and incidents.
- Operational adjustments and periodic review.
- Executive reports for permits and institutional relations.
- Documentation transferrable to recurrent operations.
How We Work
1) Listen
Territory, stakeholders, and operation objectives. Engineering starts outside the lab.
2) Design
Routes, schedules, and mitigation measures based on common sense and technical foundations.
3) Test
Field pilot with monitoring and citizen feedback channels.
4) Adjust and Scale
Documented learning and responsible long-term operation.
Our Technological Vision
Just as headphones with Active Noise Cancellation (ANC) can reduce engine noise in airplanes, we seek to reduce the sound signature of transport and logistics drones in civil environments and protected natural areas. To this end, we are developing onboard technology capable of canceling the noise generated by rotors and decreasing the annoyance they cause.
We are in the initial stages of development and will be publishing our findings soon.
Programs and Ecosystem
Accelerated by BF AERO and RETECH, and connected with an international network of collaborators in aeroacoustics, engineering, and operations. We believe in responsible collaboration between institutions, industry, and the community.
Our Team
An international team based in Spain with collaborators in Europe. We come from engineering, operations, and public management with a common background on drone technology. We share a conviction: only quiet drones will be able to fly in cities.
Frequently Asked Questions
Can you guarantee "zero noise"?
No. We can reduce annoyance and design operations with better perception. The key is what sounds, when it sounds, and how it is communicated.
Do you publish technical data?
We disclose just enough and with caution. Our priority is the trust of cities and the confidentiality of our developments.
Do you work only with large operators?
No. We also work with local administrations and pilot projects that seek to do things right from the start.
Shall we talk about your operation and your city?
Let's schedule a diagnostic session to understand the challenge and propose an actionable acoustic plan.
