Replace sections that have low volume with silence in Adobe Audition

Question

I'm annoyed by certain sections of my long audio file that involve breathing and other mouth noises. I want to silence (not delete) these sections automatically. How can I do this?

So for example, sections like this (highlighted):

Ideally I can set the maximum volume a section is allowed to contain, and everything below that is silenced. Sort of like a reverse hard limiter.

I don't know Audition, but most DAWs come with a noise gate. Use one with a filter to more accurately hone in on the right frequencies.

Alternatively, for something much 'smarter' you could use something like Waves DeBreath, specifically designed for the task.
