Put sound back on Siri, it's dangerous

I know Siri doesn't beep anymore and it's not a bug. I consider this a dangerous change. If you're in the car, you can feel the button and hold it and hear that Siri is listening. Without sound, you must look to see the light moving to make sure it is engaged. Dangerous to take your eyes off the road. Let's convince Apple to put the sound back on.
