If you want to turn one of your rooms in the home into a home studio, bass noise is often a problem that can be expensive to address so this article explains how you can do this with minimal outlay and using generally available materials.  This article is being written for people that are used to doing home DIY or are able to utilise someone that is used to using hand tools.

 Bass noise is lower frequency noise created by some drums or deep sounding wind instruments such as the tuba and these sounds build up in right angled corners thus amplifying the sound and making it more easily heard in other parts of the building.  So to eliminate these right angled corners, here is what you need. 12.5mm ordinary plasterboard in sheets 1.2m x 2.4m (4ft x 8ft)50 x 25mm battenFixing screwsLoft insulation type mineral wool 

These instructions are assuming the room to be treated has a normal ceiling height of 2.3m because the plasterboard is only available in a length of 2.4m.  The following is what to do.

diagram of reducing bass noise by fitting angled plasterboard to a wall


1.  Place the bottom edge of a sheet of plasterboard against the bottom of the wall with the top edge tight to the ceiling.  The plasterboard should now be at an angle as shown in the diagram.  If too long, cut down to the required length.

2.  Mark the position of the top edge on the ceiling by drawing a line.

3.  Remove the plasterboard then make another mark on the ceiling 12.5mm towards the wall from the original line drawn.

4.  Cut to the required length the batten and screw it to the ceiling.  Plasterboard plugs may be required for the screws.

5.  Fit into the void behind the batten the loft insulation.  (It may be necessary to glue it to ensure it stays in place.

6.  Now replace the plasterboard and screw it to the ceiling batten which should secure it in position.

7.  Treat the two opposite walls in the same way then the two remaining walls.  With these it will be necessary to trim the edge of the plasterboard nearest to each corner to allow for the angle now formed on the adjoining wall.

That’s it.  Job done.  The room is now acoustically treated to stop bass noise build up along with standing waves and all that is left is to carpet the floor and install adequate sound absorption such as our EggBox type sound absorbing foam on the walls and ceiling to help absorb reverberation and tune the room to your exact requirements.
