Need help removing sound below a certain dB

… Is there any way to basically delete any sound below a certain dB? In this case I think below -50dB…

Noise Gate

And just to make sure, will this remove the noise, or just reduce the volume/dB…

It’s called a noise gate, but it does not know what noise is, it just attenuates any audio below user-specified threshold.
