Article: A New Listening Room Part One

[Ralf11]

Agree - the length is the first thing that struck me.  A nice wall to allow access behind the electronics??

 

OTOH, the ceiling is not flat so conv. room size calcs. need to be adjusted...

[Ralf11]

yup - time for some ray tracing, followed by a light shower of diffusers 

[Ralf11]

imagining that each surface is a mirror works well for high freq.s - not at all for low freq.s - you can have someone hold a real mirror and slide it along the wall too

 

acoustics IS a science, but in practice, it is a very complex science - there are lots and lots of things you should take account of - compare with the practice of medicine: also a science, but you have to first gather signs/symptoms, then work backwards along the chain of physiology to what could be causing them (it takes more than a few years to learn that)

 

you need a way to parse your problem... that is really what expert #3 should be doing for you

[Ralf11]

3 ft. will be fine

 

or closer and use room tmts. behind your seat

 

Master Handbook of Acoustics by F. Alton Everest  (Author), Ken Pohlmann (Author) should be your bible

 

Springer has a tome out also

 

this is not rocket surgery

it's all absorption foam - no tube traps or diffusers?
