A sounding NO!!
This is just government wanting to install some device to shut off the sound on your TV, at their will and control. They could then regulate which channels in the world you can watch or not hear what is going on.
Paranoid? NO. When I was in Vietnam government did their damnedest to control what we could listen to. It elicited an entire underground radio network run off of PRC radios, who could pump acid rock to the troops.
BESIDES, they already have a device for your TV if you want it installed.

Uh...no.
It requires the provider (Comcast, DirectTV, etc.) to put a Limiter on the maximum volume on the content they deliver..
In professional audio, Compressor/Limiters are used. They are overly used on FM radio stations. It takes very quiet passages and raises the volume (compression) while bringing down the loudest passages to a lower ceiling (limiting).
I've been wanting television manufacturers to install a simple Limiter in the circuitry for years. I think a few of them have. But on the whole, private industry has not done the job on this. The government (the people) own the airwaves, and we do not need to be aurally abused in our own homes every time there is a commercial break.
I, of course, voted yay.
