It provides no hearing protection and results in both pilots yelling into each other’s most hearing damaged ear.

they’ve done studies, even in “quiet” aircraft like the Airbus pilots hearing in their open ear is generally worse than the one protected by the ear dic.

Every single communication related snafu I have had here has been with pilots using the ear dic. Every single one. I am not a soft talker either.

It needs to get added to the FSAP form and ALPA needs to start taking hearing loss/communication seriously.
