Problem With Trying To Take Out The Low Pitch of The Background Noises Without Taking Out The Low Pitch of The Speaker

A few days ago I edited three podcasts. I am blogging about one thing I wish I knew how to do: take out a background noise that is the same pitch as the main noise. As an example, I was editing the second podcast. It was for my dad's business: 10k To Talent (http://10ktotalent.com/), and my mom and dad were talking. they were at the lake club (a public place for people to come and have fun and stuff) on the deck of the clubhouse that was looking out on the lake. That night the clubhouse was having a karaoke night so you could hear singing and people talking in the background through the hole podcast. When I was editing it, I couldn't get out the background noises because they were in the low pitch, so if I took it out, it would take out the low pitch of my mom and dad. 

Here is a part of the podcast:

Hopefully, I can find a solution to this problem on the program "Adobe Audition."
