Tesla Active Noise Reduction 12 14 21 HD 720p

This a test of Tesla active noise reduction (definitely not cancellation at this point) in software update audio settings. The drive was in our 2021 Model S Long range with 19“ wheels Conti pro contact all season tires. The road is a rough chip seal road that is quite noisy so thought it would be a good place to test the feature. Sorry the camera didn’t catch the phone screen when trying to measure noise level because I was trying to get it close to the headrests since the setting said it is most effective there.
