Am I the only one who listened to the video and didn't have anything happen with my tensor tympani? I can voluntarily control mine ("ear rumbling") so I know what it would feel /sound like.

Unless you played it pretty loud, nothing should happen. What speakers did you play it through, and at what volume?

I played it at max volume on my P30 Pro next to my ears and didn't hear anything... I'll try a more scientific test with an actual loudness measurement later.

Earlier quoted context omitted.

I mean, the actual implementation of this feature could have been a few hours work... Let the media center detect airbag deployment on CAN bus, then play a pre-saved quarter second audio sample at a fixed volume. There might be complexities if the audio system is turned off and needs to boot up, but my guess is on all modern cars, the audio amplifier etc. is always turned on, even if the radio appears 'off'.

> the actual implementation of this feature could have been a few hours work... Yeah, but nothing in the car world is that easy. First you need to fit this to all cars. Then you need to test it (not that cheap), document it extensively (safety level, failure states, activation conditions, ...), check that it actually does what it's supposed to do instead of for example worsening it and then you need to get it certifi…

Still feels like it could be an OTA update in a Tesla. The "car world" needs to change and change has begun.

I wish fire alarms did this for half a second before blasting your tympanic membrane with an ear-splitting noise. Residential ones are bad enough, but the ones in offices are the worst.

That's a good idea! I bet if someone were to develop a residential smoke detector that did that it would sell well. (Especially if it had other compelling features like a 10-year battery.)

US fire codes require smoke alarms to be replaced every 7 years.
