Is there an engineer type on here could explain that?

Sorry Tony. What your friend told you has only to do with terrestrial radio. Those stations you get on your wireless. We were required by the FCC to have a "modulation monitor". That is an audio compression (and expansion) device that keeps the modulation (audio level) constant from event to event. There are some pretty stiff fines for modulation over 100%.
Enter cable TV and Radio. All bets are off. No modulation monitor here. The audio of the commercials is at least 15% to 20% higher than the programming. It is possible that programming is being delivered at 80% modulation and the ads are 100%, but I don't think so.
I made my living for 40 years airing commercials. Now, I push the mute button when they come on.
