Dear Mr Der
I came across your
interesting site while looking for information about how
to create an audiology room. I have a few crucial
questions and I would be grateful for any answers you
could give me.
I am setting up a private
ENT practice in what has until now been a residential
appartment. I have selected a room which I intend
to insulate as best as I can and also acoustically treat
to reduce reverberation. I intend to use it for
paediatric audiology testing, such as distraction
testing and VRA. I will create an observation
window in order to stay outside the room while
performing VRA.
Are there any minimum
numbers or set ratios for the length, width and height of
the room or any size would do for as long as it is
calibrated?
Are there any materials
which you could propose that are relatively thin yet
effective for sound insulation and/or acoustic
treatment?
Is it a realistic effort to
acoustically insulate a room with standard brickwalls by
lining the walls, ceiling and floor with insulating
material or do I really have to rebuild the walls in
order to make any difference? If the latter is the case,
will it make any difference to do this on the two walls
that I can (I cannot bring down the other four sides of
the room) or would this make no essential difference?
Do I have to keep the size
of the observation window to a minimum or does it not
really matter a lot for as long as it is specially made
for sound insulation?
Many thanks for taking the
time to read my e-mail! If there is anything else
you might think that I need to know, I would be grateful
for your advice.
Kind regards
