you need to get a DC pump with SINE technology...... cheapest one is Jebao DCP pump, cheap and good. You can opt for the DCP5000 or 6500 for your 4ft tank which is less then $150

Using a DCP5000. Works great so far.

Very often, hard plumbing increase sound as the vibration cannot be dissipated.

You can place the pump on a rubber mat if it does not come with rubber feet.

Else, connect to the pipes with a silicon hose. Sample pic from internet.

 

If its not a new pump, the sound could be coming from worn out bushings or unbalanced impeller.
