Your listening room

Strange as this may sound, the room itself will have a profound affect 
on how your audio system responds.   In fact, many experts consider 

the room to be as important to the sound as any other component in 
your system!  

Did   you   ever   notice   how   it’s   difficult   to   talk   in   some   restaurants 
because   you  can’t   hear   each   other   over  all   the   other   conversations 

going   on   around   you?     Yet   another   similarly   sized   restaurant   is 
perfectly suited to intimate romantic murmuring.  The difference lies in 

the surfaces around you.  Here is a simple test – go into your bathroom 
and   clap   your   hands;   then   clap   them   again   in   a   room   with   carpet, 

curtains and other soft furnishings.   Notice the difference?   In a room 
with many hard reflective surfaces sound waves bounce around a lot 

before dying out.  Not even the most expensive stereo in the world is 
capable of sounding good in such a challenging acoustic environment.

When   it   comes   to   your   listening   room   the   same   principles   apply. 
Wooden   floorboards,   polished   concrete   and   slate   tiles   are   all   highly 

reflective surfaces.  In a room without curtains or other wall furnishings 
the sound may be overly ‘bright’ or aggressive.

Similarly, it is possible for a room to be too ‘damped’ or absorptive. 
Where   there   are   no   reflective   surfaces   at   all   the   sound   may   seem 

‘dead’ or lacking in energy and excitement.

Luckily for us, most  household rooms  are a combination  of the two. 

And, generally speaking, a combination of the two will bring about the 
best results.

Too many hard surfaces?

If your room is too ‘bright’, try placing a large rug on the floor between 
your   listening   position   and   the   speakers.     Or   hang   some   soft 

furnishings from the walls.

Too many soft surfaces?

If your room is too damped, try removing some of the soft furnishings 

from the walls or rugs from the floor.

Managing the bass

Sometimes, low frequency waves can also bounce around and cause 

problems in a listening environment.    This may be the result of the 
shape   of   the   room,   or   the   materials   it   is   constructed   from.     Large 

pieces of furniture in a room can often help to break up these ‘standing 
waves’.

While few of us will feel the need to totally redesign a room to improve 

its sonic properties, sometimes a small change, like placing a rug on 
the floor, can make a big improvement to the sound.
