I have a question about Destroyers and Depth charging

That is true. The destroyer is blind for minutes after the attack run. I remember listening to some audio clip from tests how depthcharge affects hydrophone and some of the explosions could last as long as 60 seconds.

Here's a great site with lots of audio clips (I think the clip I mentioned is somewhere there) from hydrophone training and some from real attacks:
