This is one example of an idea whose time has come. Today’s factory and aftermarket stereos are louder than ever and today’s vehicles are more sound insulated than ever. Those two things combine to make it virtually impossible to hear emergency vehicle sirens when listening to loud music. The most common devices being tested would sense the siren and either turn down the volume of the stereo, mute the stereo, or sound an alert type sound over the music. I’d question if a radio broadcast siren sound would fake out the sensor or is the sensor an external microphone?
If something like this is put into mass production which would you prefer; turn down volume, mute volume, sound an alert, or the option to select one of the three allowing the vehicle owner to select for themselves. I’ll create a poll after this post.
I initially said mute volume, but.. Think of a situation where you're driving to get out of the way of a tornado or similar, and you're listening to the radio for instructions while fire, police and rescue vehicles are all around you.
I'd prefer better risk avoidance training to instill some sense into the driver instead. Self-determination and all that. Not another mommy-state electronic system that can and will fail. If you can't hear what's going on outside your car at all, there's a problem. What about NOT designing the car to be so insulated? It can still be built to muffle road noise. Emergency response sirens aren't the only potentially hazardous things you need to stay aware of while operating a car. Still, no matter what "safety" features a car designer creates, it's owner can usually find a dumb way to disable it.

I say we just make cars that turn off as soon as EV is maybe 200 ft away. Let's make it 400, just for the sake of the children.
Also, I'd like to have a gizmo that points siren direction. Way too many times I am creeping into intersection without being able to tell, where the heck that noise is coming from. City muffles direction easily.
I regularly check my mirrors, so I know when an emergency vehicle is approaching and pull over well ahead of them trying to overtake me. I often witness other idiots pass me like I pulled off to the right and stopped for fun... I will blow the horn and they just keep on going like I was giving them a friendly "hello".
I don't anything will get through those folks thick skulls.

None of the above. I don't want any of the options. 98% of the time I see the flashing lights before I hear the sirens. The other 2% of the time I will see the flashing lights in time to yield. I don't need to hear the sirens at all. Sirens are just unnecessary noise.

So in heavy traffic all of the cars on the road will be disabled? How will the EV get through if all the lanes are blocked with disabled cars?
You could have sirens simulcast on a broadcast frequency, with all cars equipped to override the sound system. The louder you turn you speakers, the louder the siren becomes in your car..

That was my first thought, as well.
As if EV operators don't already have it bad enough trying to navigate through inattentive idiots who refuse to pull over when an EV is approaching.
