> This is a major reason that people pay for premium lounge access, it is not the food, nor the booze but the quiet that is the true luxury.

Not true for middle-class lounges such as Centurion, Priority Pass, and most airline lounges (Polaris, Flagship, Senator, Singapore, etc).

Most go for food or drinks. The lounges are often crowded and loud with silverware, plates, kids, and TVs.

For elite lounges such as the Private Suite, Lufthansa and Emirates First Terminal, yes, quietness is a big selling point. But at this point, you’re on the vector to flying private domestically.
