He's calculated the ceiling insulation without taking into account the ventilation ducts which are now fitted. To wrap all of these ducts will be a considerably larger quantity of insulation, whereas the drop ceiling is completely flat. I think I am going to allow him to do this, with conditions. | |

| Jun 14, 2012 at 13:32 | comment | added | BMitch | @mark, fair point, I should do a better job at answering the question you asked. I've updated my answer. Short version: I can see the possibility of slightly better sound insulation in ideal conditions, but I can also see a long list of issues. | |

| Jun 14, 2012 at 13:03 | comment | added | mark | Thanks again. For sure these are considerations but really my concern at this moment is this issue with having the sound insulation laid on top of the drop ceiling, rather than attached to the ceiling a short distance above. I suspect this is the easy path for the builder and that the echo as justification is a falsehood. | |
| Jun 14, 2012 at 12:51 | comment | added | BMitch | I should avoid words like "only" since there can be some echo of sound off the floor above, but I don't believe it will be the majority of your problem, especially the high pitched sounds from children. Focus on the solid unobstructed surfaces in the room for the best benefits, e.g. solid walls and hard floors. | |
| Jun 14, 2012 at 12:08 | comment | added | mark | Thanks for your reply. I must say though that this conflicts with what I've read elsewhere, that unless a suspended ceiling absorbs all sound then it will hit the actual ceiling and reflect. While our drop ceiling tiles have acoustic properties they by no means insulate the space above to any great extent. | |
