Cabin noisefor the "works in noise" demo

Use a real cabin recording instead

Generated noise is used until you load a file. The file stays on this laptop.

How to run the noise demo

1. Play this page through a speaker next to the passenger phone.
2. Measure the level where the phone is with any sound-meter app, and show the number to the jury. Real cabins are often quoted at roughly 75–85 dB(A) in cruise; treat that as a guide, not a measurement.
3. Speak the request on the passenger screen. Show the result on Under the hood: the silence filter, the guesses, and the match despite the noise.
