acoustic ventilation

Air conditioning, fans, and anything related to keeping it cool, such as insulation. This would include any posts generally discussing how to keep it cool, such as which types of blocks are better insulators.... ideal wall thickness for keeping an A/C house cool, etc.

Anyone used acoustic vents?

I have AAC cavity walls with a 10cm cavity, and I'm wondering about these if they are useful for keeping the cavity 'fresh' or if it's not important. Also whether they aid in cooling a building that is otherwise has no AC and is designed for low noise penetration from outside.

I too have cavity AAC walls. The noise comes from the windows and doors (glass) and nowhere else.

right, my point was whether these particular vent bricks are useful for ventilation/passive cooling, in the tropics.

Ventilated cavity? 10cm ? Acoustic vent having thermal properties?
I think you have a confused goal. For a start, a 10cm open cavity means you are only using one skin as a thermal and acoustic barrier. The outside skin is just acting as shade. The vent assumes a sealed cavity. It has no thermal properties per say.
An open cavity with aac blocks is so totally wrong application and missunderstanding of their properties. They are not cement or red bricks. They have different properties that we need to embrace. rather than as substitutes for normal bricks.
Sure they work ok as substitutes, but that is under utilising their unique properties.
