This is the kind of door I have.
But I don't know what's an effective way to soundproof it.
As much as possible I don't wanna spend much money that could reach $20 and above.
I don't have that much budget

Suspend a heavy rolled-up quilt (get it from a flea market or discount re-seller) above the door. When you are inside, unfurl the quilt so it covers the entire door and frame. probably your best option for the money you are willing to spend.
Thin weather-stripping applied to the top & right side door stop moldings & to the left door jamb beside the door stop molding. Frost King's 3/8's Triple Rib self adhesive stuff works great. Sound transmission is largely stopped when air transmission is stopped.
