Atelectasis and vocal fremitus

Why does atelectasis cause decreased vocal fremitus? I mean, there is less air since the alveoli are collapsed, so i thought that the sound should increase.

Sounds like a potential typo to me. Maybe they meant increased?

Tactile fremitus is decreased (or absent) in atelectasis.

There is more space between the lung tissue and the chest wall, since as alveoli collapse, the lung area shrinks. Similar reasoning to a pneumothorax but on a smaller scale. Open space does not transmit sound very well.

Thanks a lot!!

Increased vocal fremitus= Consolidating Pneumonia , thats all you need to know unless you are into Pulmonology..

why is there dullness on percussion then?

Is it not air in this space? or is it vaccum?
