Listening room setup + library


Hey there, 
I am thinking of remodeling a room. It should have two functions: listening / TV room and storing a lot of books. I think books are usually beneficial in a room since they can have positive effects on the sound so I hope this is possible. I made a first draft of what I would suggest. The room is rather small (3,45 x 4,75m or 11ft x 14ft). Without going into too much detail, do you think this is a good idea or are there big problems that are hard to solve? My first idea is to stuff the shelves with books, place some base traps in the front corners and put a big couch in the back with additional absorption above on the back wall. There is also the idea to integrate a window in the roof. Could this be a problem? Note that the shelves are in a U-shape and one side is not shown so the view is free. 

Thanks a lot for ideas and comments.

This could be a very interesting thread.

I don’t think 14 x 11 is particularly small but it is very sensible to gather as much advice beforehand.

I tend to prefer a live sound and would be wary of overdoing the absorption.

Alan Shaw of Harbeth once revealed that before listening to any speakers he prefers to walk around the room and listen for echoes/anomalies whilst clapping.

He also suggested the use of bookshelves, even going as far as to file them with the spine facing away if extra absorption was needed.

I just happen to have a bookcase to the left of my speakers but I prefer to be able to read the titles!

Maybe that’s the starting point, working out just how ’dead’ you want the room to sound in terms of reverb. Somewhere between a long cave and an anechoic chamber maybe? 

As for bass issues, a lot will depend upon your speakers/setup. I've never owned any speakers/subs that could get low enough to cause any issues.

I’d definitely want the window in the ceiling, it just feels much better, but it’s got to be well fitted/soundproofed.

As for general soundproofing, I’ve often said that if we were to move house I’d never want to be near a main road again.

Sure the whoosh of the traffic noise might well be inaudible when the music is playing, but it’s still there isn’t it?

My preference is that the quieter the room is, the better. There might be times when you just prefer to sit in near silence.
@millercarbon,

’Most of the noise will come in through the door. (And a surprising amount will come in through the window, even when closed.) But mostly the door. Ideally you would replace the normal hollow core indoor door with a solid core outer door and use weather stripping same as if it was an entry door. At the very least do a good job weather stripping your door.

You’ll be shocked how much noise comes in from even a small crack or gap.’



Yes, it is surprising just how much does come from the door. As you say, a fair bit from the window too - even a double glazed one.

Once you start listening for background sounds it soon becomes apparent that silence is remarkably difficult to attain.

Or even near silence if you need to need to hear the door, family members calling for attention etc.

Your advice might just be one of the cheapest and simplest upgrades anyone could make.
