Biology Series - 2: Aeroacoustics & Hearing orb
This is an amazing post from Siemens on Aeroacoustic Engineering and discusses day-to-day aeroacoustics engineering from human hearing to fans, car vent fans, and car side mirrors.
I am impressed by the article on the details and also simplicity of the language. I have worked on same to similar projects and my friends worked full level on such engineering work, and this kind of article in this industry or subject with simple English and informative video is very very rare.
When I learned this topic 10+ years ago, there weren't such pictorial books or articles, we have to break our heads with old textbooks with a bunch of math equations.
- Every part of an automobile is engineered for Aerodynamics or ergonomics including at what speed the cool or warm air from the vent has to hit the chest or face for a pleasurable experience, everything is engineered over hours and hours for a great car experience while driving or sleeping inside the car.
- Ever complained about why the hell, the side mirror is so small and needs to turn the neck to see the blind spot, it is for reduced aerodynamic drag and resultant noise. The very laborious task is to come up with the optimal design, weight, and size of the side mirror to withstand the wind speed, and noise, not break away and serve the function of viewing which the laity happily complains about how small. I don't blame them, even I have done that complained until I knew about this.
This article shows the acoustic side of things which is even more complex than handling pure fluids like air/ liquid. Great article, this has been around for a few decades in the Aerospace and Automotive industry as a niche subject, but it is getting more mainstream.
Acoustics is a tough subject, acoustics coupled with fluid & structural dynamics is even more complex. The videos let one appreciate the work that goes into it and gives a rare insight into how sound travels in these dynamics (this is ultra rare) and helps one to optimize oneself by seating arrangement or fan speed based on the movement of these sound waves. That actionable input from this video is important and one can find it easy to integrate.

Look at the psychic hearing orb at the right ear. The naad, the supernatural sound resonance does not use mechanical air/ sound waves to travel but it uses directly the psychic hearing orb to penetrate the human psyche or mind or subtle head.
