Hi everyone, Dennis Foley from Acoustic Fields. I get a lot of calls and emails from people
say Dennis I just don't have budget to treat my room but I know my room has a lot of problems
so what can I do. What we're going to do a series of videos here 1,000 2,000 3,000 what
do you have in treatment. Now you’ve got to realize for this kind of money that you're
going to have to have a carpentry skill set, you're going to have to build things yourself
and save the labor costs because acoustic treatment is all about type amount and position.
So you’ve got to build the right type, you’ve got to have the right amount and you got to
put it in the right spot. That all takes a lot of units, I mean treatment costs in professional
Studios can run fifty to a hundred thousand dollars. Some of our projects are two three
hundred thousand with treatment. So what can we do in our small rooms on a limited budget?
So let's say we have two thousand dollars, well we know our two areas of concern are
pressure and reflection, now with two thousand dollars we're not going to be able to address
all the issues so we have to break it apart. Low frequency issues are the worst, they're
the most expensive to treat, they take the most amount of product and cover the most
surface area so the bottom line is we’ve got to address that first so pressure is going
to be our first priority. With pressure we have the low frequency issue and then we have
all the harmonics so we may have a 40 cycle problem and then we got 80, 120, 160, 200…
so we got all that going on, type, amount, position…
So what are our options for low frequency? We know that it's membrane, Helmholtz and
diaphragmatic. Helmholtz is difficult to build, frequency specific, need a lot of units got
to put them in a lot of places in the room. Membrane and diaphragmatic are broadband but
diaphragmatic has the most horsepower of the two and then with our carbon technology you
can get a lot of horsepower in a small amount of space. So what are we going to do with
$2000? How are we going to dress this? Well we're going to focus on the low frequency
pressure first and then we're going to have to build the unit's ourselves and you know
from our website that we offer a whole series of DIY build units and in this particular
case we're going to build the unit that's called the BDA and it's in the DIY section
of our website, just go to shop under the DIY section. Now the thing about the BDA is
the units are 2 foot x 4 foot, you can make them bigger depending on what your skill set
is and what kind of shop you have to build them. You do need a carpentry skill set to
build them, you need to be able to run a table saw. So what are we going to do with $2000?
Let's just walk through an example of how this would work, the build materials in most
areas per unit is about $150, it's mostly 1 inch MDF, ½ inch MDF, 3/8 inch MDF okay.
The carbon technology which we can license and sell to you runs about $350 a units so
for $500 a unit and your labor you can have four units for $2000 alright. So if you want
to stretch a little bit then we can add foam to the face of each unit to then start to
manage the reflections. So if we have $2,000 you know we can build four units and we could
get enough horsepower in terms of square footage to do something so break your room requirements
down in the low-frequency issues and reflection and let's treat the low frequency issues first.
Is 4units in most small room going to be enough? No but it'll be a start and you can phase
it in especially when you have a limited budget. Thank you
