What I am referring to is "damping", not reduced sound transmission. While the results may be similar, the mechanism is different. As I understand things, damping is preventing the re-transmission of sound --- either internally and externally. That's what I'm looking for data on.

No, the discussion here is not limited to the COST of one type of block over another. Read the title. It is about Pros and Cons.
FWIW, a porous / fibrous material between layers of mass doesn't do all that much for reducing sound transmission. Fiber board and fiber blankets work well to reduce the reverberation of sound within a space, but I'm not sure how important that is inside a residential wall.
However, I don't think it is about atomic bomb shelters.

It is difficult to sort of imagine one's way, acoustically speaking, through a breeze block wall. Each block is complex with 'chambers', 'walls' and 'connections'. But a double Superblock wall might have some significant advantages over a double breeze block wall.

Yes double or treble the cost.
You are beginning to sound like some of the artchitects

Hi,
Im trying to figure out why someone would spend say 25 to 30BHT on one of the lightwieght "breezeblock" type products versus for example
simple concrete blocks made by locals at 4bht a piece, also the small terracotta bricks that are mere Satangs a piece.
Has anyone done a compartive analysis of these 3 types of building materials to ascertain which one actually represents good value?

( " However, I don't think it is about atomic bomb shelters." ) Acoustically speaking there pretty good at it.
I am in the process of blocking in the garage door (this is a DIY job) had the breeze blocks delivered today,4 Baht each, and yes they are brittle, especially when wet after a nights rain, they are now drying off under cover.
So here are the questions what is the best thickness for the render? As I have seen that it varies so much.
What is the best rendering product/name and what is a good mix ratio?
I could get someone in to do the job but I tend to like hands on.
The photos are my last DIY job, all good for the waistline,
