Buzzing Air Taxis are Coming. The Race to Design Quieter eVTOLs is on

The future of rideshare could be airborne — if designers can mitigate the noise these aircraft produce. Many air taxis are eVTOL (electric vertical takeoff and landing) aircraft, which use multiple small rotors operating at lower speeds. Rather than producing a single dominant sound, these rotors generate overlapping frequencies, resulting in a more complex, perceptible noise profile. While they are generally quieter than helicopters, the sound of multiple rotors whirring is widely considered more annoying to the human ear. The…

A Letter from Anna

Welcome to the Build Better –what started as a work in progress Handbook documenting what I've learned from admired leaders, my experiences, and observations from over 100 NPIs, has now become a hub for sharing manufacturing lessons.

When Samuel Weiss and I founded Instrumental in 2015, we aimed to eliminate inefficiencies in electronics manufacturing. Starting with a bold idea, minimal funding, and professional credibility, we sought to create tools to build the best products. Today, our mission is broader: empowering engineering and operations teams to excel.

Through years of industry experience, I've seen that challenges aren't just technical but cultural. Leaders learn best from peers, and Build Better aims to share their insights and frameworks. Divided by product lifecycle stages, it includes leadership lessons, tactics, and practical content for daily operators. We cover news, create video content, and host our Annual Summit every fall.
