Back in the '80's I had a VU/RMS LED display that 'tracked' either with reasonable accuracy. Was 'bout 2"h.x9"w.x6"d. ....
VU was easy, a line input wherever you wanted to tap in.
RMS? Forget how that was accomplished, but 30+ years wipes some details away.... But it did illustrate that 1 watt (average) into a living room could be loud enough....
The 'peak' readings, however, could be pretty substantial. 150 peaks could drive one out of the room...
