How To Soundproof A Room On A Budget

 I have an office in my house. It is a spare bedroom turned into an office. It's not large but contains my desk, computers and books.

There is noise in the house. It comes from television, children, music, and general house activity.

When I am working I like quiet to think, write and create.

My office is way too noisy.

Sound travels through open spaces and thin walls and glass.

I can see that my door has a gap underneath. Sound will creep through there. The first port of call for sound proofing.

I also know the gap around the door is an avenue for sound to creep in. My second port of call for sound proofing.

I also have a window in the room. It is sealed but noise still travels through the thin pain of glass. My third port of call to sound proof.

The walls are brick and plaster so I don't think I will need anything for them.

The cost to sound proof the room professionally will be expensive. Way up there. It is not something I wish to do.

The alternative is DIY soundproofing.

Can I soundproof my office effectively with out spending more than say a few hundred dollars?

The answer is yes I can.  And, I can do it myself.


Lets tackle the door first.

I need a seal on the bottom of the door to 'fill the gap' There is no carpet on the floor, it is tiled.

There are a number of options I can choose but I don't want something that is going to scrape on the floor as the door is opened and closed. A brush seal or rubber seal at the bottom of the door will drag along the floor. It will leave unsightly marks.

What I need is a drop seal. It raises when the door is opened and drops when the door is closed. It will fill the gap and not leave unsightly marks on my floor.

As I am doing this my self I do not want to take the door off and have something routed into the bottom of the door. Nice but expensive.

What I have chosen is the Lorrient LAS8002si Auto Drop Seal which is a surface mounted drop seal. The seal is roughly 35mm high and 14mm thick so not too intrusive.

I will place the seal on the external side of the door as the door opens in. However, as the seal is made from an aluminium housing, I shall paint it to match the door finish.

This seal is screw fixed onto the door. Two screws and it's on. The end caps clip on and there is  a plate on the pin side that controls the up and down movement of the internal seal hitting the floor.

All I need do is cut it to the right length of the door and mount it at the right height on the bottom of the door so the seal connects with the floor.

Job done.


Now for the gap around the door.

There are some commercial style door seals that fit around the door frame which will be too expensive and I don't like the look.

The best affordable option I have to seal the gap around the door is to use what is called the Lorient LAS1212 Bat-Wing Seal. This seal sticks to the edge of the door frame where the door close into. The adhesive is strong so there is no thought of it coming adrift in the future.

This is a nylon type durable seal with wings, and easy to cut to length. I will attach this to the top of the door frame and down both sides of my door frame. 

This will ensure a firm fitting seal all round and with the bottom drop seal the sound will have difficulty penetrating this door.

Job done.


The Window

As to the window. It currently just has basic curtains which are light.

Time to invest in some blackout curtains which will help keep the sound out.  There are some good choices on the market and it pays to shop around to find what you are looking for.

I found a blackout curtain and with a little modification to hanging them, they are perfect. They are wider and longer than the window itself and I can fasten the curtain sides to the wall with a couple of hooks. 


Did it work?

OK that in a nut shell is how I soundproofed my office.

Has the sound decreased? Yes more than expected.

Of course there is a lot more one could do with acoustic foam but then the expenses would go up and up. Do I need to? No!

With the minor DIY fittings I have installed, the sound levels are way down to what they were and my office is quiet enough for me to carry on working without disruption from household noises.

Total cost: under $150.

Time: just a few hours for me to potter around doing things.

Is this the be all end all? No. You can do a lot more to soundproof your room or home. On a small budget this was more than acceptable. If you have greater funds then you can spend what you need to upgrade your soundproofing project.  

Worth it? Yes for me it was worth it. Might even do the kids rooms but don't tell them!
