Before spending money, consider a solution instead of a band-aid. None of those solutions may work all the way. And a gravity drain should be silent-running all by itself.
Anecdote: My work desk is next to my tank, so the gurgling most folks seem to tolerate OK wasn't cutting it. My drain boxes came with maggies, I built my own, I built a durso...at best they helped "a little". Of course, YMMV...
It may be the case that you are running too much flow through your drain and that is the cause of the noise.
Find a way to measure the flow through the drain.
For example:
In most cases, your needed flow rate can be calulated as:
I've done x5 in some cases, but more than that is usually just wasteful....and annoying. 
It's helpful to know what your actual flow rate is anyway, so you might wanna measure regardless of what you do with the drain/noise.
(Note, pump and drain flow-ratings are not the same as what I'm talking about.)

Find a way to measure the flow through the drain.
For example:
- Use a container of known volume placed under the drain or return.
- Time how long to fill.
- Convert volume of container and time to gallons and hours.
- See if you're beyond the needed flow rate for your sump applications.
In most cases, your needed flow rate can be calulated as:
[Display Volume] x2 = [Actual Flow Rate Thru Sump]
...or up to x4
...or up to x4
