Sound insulation is primarily about mass. Ytong is bad in this regard, but I could imagine that they might even be better in longitudinal sound than unfilled bricks. However, I do not know this! You will find many posts from dissatisfied homeowners with these bricks. Also, in my circle of acquaintances, there are many complaints. I myself am not that dissatisfied, but overall I would still go for filled ones next time.

To those who also have aerated concrete interior walls. Which type of block did you use?

The differences in the sound values are not insignificant.

Example 175mm block:
Ytong PP 2-0.35 0.09 39.0dB
Ytong PP 4-0.50 0.12 43.6dB
Ytong PP 6-0.65 0.18 46.3dB

btw. Ytong has once again increased prices for 2020 by the typical 8-9%...
