I am a total beginner to playing bass and when I press down on the strings to fret it makes an undesired noise as the string comes into contact with the frets. Is there a way to prevent this? Thanks
It's probably fret buzz. Take it to a guitar shop and see if they'll fix it for you.
so your doing an unintentional hammer on???

more experienced you get the more youll be able to control this, either by palm muting or by become gentler with your fretting hand, as for now try turning the gain down.
