The Eiger Is Quieter Than You Think: A Leap Forward in Drone Acoustics
Imagine a drone designed to be barely noticeable, even in environments sensitive to noise. Not just a vision for the future, it’s happening now. RigiTech’s latest acoustic tests reveal that the Eiger UAV is one of the quietest drones in its category, with noise levels lower than many common urban sounds. This breakthrough reinforces Eiger’s potential as a sustainable and community-friendly solution for medical logistics.
Extensive testing was conducted per FAA acoustic protocols, measuring sound exposure at various distances and under different flight conditions. The results show that during cruise flight, the longest phase of a delivery, the Eiger emits only 51 to 55 decibels when measured 135 meters from the flight path. That is quieter than a typical conversation.
Even during hover or vertical flight phases, where sound levels naturally rise, the Eiger remains within the range of everyday sounds. Only during takeoff and landing, brief and localised events, does the noise level approach that of household appliances like a blender or power tool.
A visual comparison with familiar sounds helps put these numbers into context. The Eiger in cruise flight is quieter than traffic, quieter than a vacuum cleaner, and even quieter than casual conversation in a busy office. This means Eiger can operate in populated areas without disturbing communities, a key factor for the large-scale adoption of drone logistics.
Why It Matters
Reducing drone noise is not just about performance. It directly affects how these technologies are accepted by the public and how easily they can be integrated into everyday environments.
Low noise levels are critical for operations in noise-sensitive areas, particularly for healthcare deliveries around hospitals and laboratories, where maintaining a quiet environment is essential.
This advancement supports RigiTech’s mission to enable reliable, sustainable and unobtrusive medical delivery networks. The Eiger now offers not only long-range performance and high payload capacity, but also the discretion and environmental consideration needed to operate in real-world conditions.
Every flight we make saves time. Sometimes, it saves lives. Now, it does so more quietly than ever.
