Ideal Room Dimensions: Is the golden ratio really that good? - AcousticsInsider.com
Summary
TLDRJessica de Acousticsinsider.com explora si la proporción áurea es efectiva para las dimensiones de una sala en tratamiento acústico. Comparte su investigación sobre la relación entre la altura, ancho y longitud de una sala usando la proporción áurea y otros métodos modernos. Muestra que, aunque la proporción áurea es teóricamente interesante, puede no ser la mejor opción para evitar modos de sala y sugiere que no se obsesione con la perfección en la optimización de la sala.
Takeaways
- 🎚️ El vídeo trata sobre la relación entre la proporción áurea y las proporciones de las salas y si es realmente buena para las proporciones de la sala.
- 🏠 Se menciona que la proporción áurea sigue siendo popular y se desea probar esta teoría con estándares más modernos.
- 📏 Se explica que las proporciones de la sala se calculan a partir de la altura de la sala, considerando la altura como la unidad base y multiplicando por un factor específico para obtener las proporciones.
- 📐 Se proporciona un ejemplo de cómo se vería una sala pequeña siguiendo la proporción áurea con una altura de techo de aproximadamente 8 pies.
- 📏 Se comparan la proporción áurea con otras proporciones de salas recomendadas por expertos en acústica.
- ⚠️ Se advierte que la optimización perfecta de la sala no es necesaria y que estas proporciones solo funcionan en salas cuadradas.
- 📊 Se utiliza el Amarok Room Mode Calculator para calcular las frecuencias en las que ocurren los modos principales de la sala y se visualiza la distribución de los modos.
- 📊 Se menciona que la optimización de las dimensiones de la sala no evita los picos y valles en la baja frecuencia, sino que proporciona una base para un bajo frecuencia más uniforme.
- 📊 Se discute la importancia de que el número de modos de sala en cada tercio de octava de frecuencia aumente gradualmente o al menos se mantenga constante, según la teoría de Bonello.
- 📊 Se evalúan varias proporciones de salas, incluyendo la proporción áurea, y se observan sus resultados en términos de área de bola y gráfico de Bonello.
- 🔨 Se enfatiza que no se debe obsesionar con estas proporciones teóricas, ya que la distribución real de los modos de sala en la práctica puede desviarse mucho de estos cálculos.
Q & A
¿Qué es AcousticsInsider.com y qué enseña Jessica?
-AcousticsInsider.com es un sitio web donde Jessica enseña técnicas de tratamiento acústico para profesionales de audio, pero sin la complejidad que a menudo acompaña a este tema.
¿Cuál es el tema principal del vídeo?
-El tema principal del vídeo es discutir las proporciones de las habitaciones y, en particular, la relación con la razón áurea, para determinar si es realmente buena cuando se trata de las proporciones de las habitaciones.
¿Qué es la razón áurea y por qué es importante en la acústica de las salas?
-La razón áurea es un concepto matemático que se considera esteético y armónico, y se ha utilizado históricamente en la arquitectura y el diseño. En la acústica de las salas, se cree que las proporciones que siguen la razón áurea pueden mejorar la calidad del sonido.
¿Cómo se calcula la razón áurea para las proporciones de una habitación?
-Se toma la altura de la habitación como la unidad de altura (1) y se multiplica por ciertos factores para obtener las proporciones de ancho y largo, que son 1.6 y 2.56 veces la altura respectivamente.
¿Qué otros métodos se mencionan para determinar las proporciones de las habitaciones además de la razón áurea?
-Se mencionan otros métodos como los de Seppmeyer, Loudon, Forkman y Boner, que son alternativas para determinar las proporciones de las habitaciones.
¿Qué es el cálculo de la moda de la habitación y por qué es importante?
-El cálculo de la moda de la habitación es un método para predecir las frecuencias en las que ocurrirán los modos de resonancia en una habitación. Es importante para entender cómo se distribuirán estos modos y cómo afectarán el sonido en la sala.
¿Qué es el gráfico de Bonello y cómo ayuda a evaluar las proporciones de las habitaciones?
-El gráfico de Bonello es una herramienta utilizada para predecir cómo buenas son las proporciones de una habitación. Muestra cómo se distribuyen los modos de la habitación a lo largo del espectro y si hay acumulaciones de modos en ciertas frecuencias.
¿Qué es el área de Bolt y cómo se relaciona con las proporciones de las habitaciones?
-El área de Bolt es una representación gráfica que se utiliza para evaluar si las proporciones de una habitación son buenas o no. Si el punto resultante de las proporciones de la habitación se encuentra dentro del área de Bolt, se considera que tiene una buena distribución de modos.
¿Por qué no se debe obsesionar con obtener las proporciones perfectas de la habitación?
-No se debe obsesionar con obtener las proporciones perfectas porque las habitaciones reales suelen desviarse de las proporciones teóricas debido a factores como la presencia de puertas, ventanas, la construcción de las paredes y el piso, lo que hace que los cálculos teóricos sean menos relevantes.
¿Qué es el marco de tratamiento de estudio de casa de Jessica y cómo puede ayudar a los usuarios?
-El marco de tratamiento de estudio de casa de Jessica es un conjunto de cinco pasos que guía a los usuarios en el proceso de tratar su estudio de grabación. Ayuda a asegurar que se realicen las tareas correctas en el momento adecuado para mejorar la acústica de la sala.

🎵 Análisis de la Razón Áurea en Acústica de Estudios
Jessica, de acousticsinsider.com, vuelve a explorar la relación entre la razón áurea y las proporciones de las salas de grabación. Ella desafía la idea de que la razón áurea es la mejor opción para las dimensiones de una sala, y decide probar esta teoría con estándares más modernos. Presenta una comparación entre la razón áurea y otras recomendaciones de proporciones de salas, como las de Seppmeyer, Forkman y Boner. Jessica explica cómo se calculan estas proporciones, teniendo en cuenta la altura de la sala como la unidad de referencia y multiplicando por ciertos factores para obtener las dimensiones. Además, menciona que estos cálculos solo son teóricos y aplicables a salas cuadradas, ya que cualquier desviación de la forma cuadrada afectaría los modos de resonancia de la sala.
📏 Optimización de Dimensiones de Sala y Modos de Resonancia
Jessica explica que la optimización de las dimensiones de una sala no es un medio para eliminar los modos de resonancia, sino para distribuirlos uniformemente y evitar que se superpongan. La distribución uniforme proporciona una base para un buen bajo extremo una vez que se empieza a tratar la sala. Se utiliza el cálculo de la razón áurea como ejemplo, mostrando que hay un gran vacío en la distribución de modos, lo que no es ideal. Luego, compara esta con otras proporciones, como las de Seppmeyer, que parecen tener una distribución más uniforme y sin acumulaciones de modos en las frecuencias más bajas. Jessica enfatiza que aunque estos cálculos son útiles, en la práctica las dimensiones reales de una sala pueden variar mucho y que no se debe obsesionar con ellos.
🏠 Conclusiones sobre Razones de Salas y Tratamiento de Estudios
Jessica concluye que, al menos en este ejemplo, la razón áurea no es la mejor opción para las dimensiones de una sala de grabación según los estándares modernos. Ella sugiere que otros métodos, como los proporcionados por Seppmeyer o Loudon, podrían ser mejores opciones. Jessica recuerda que estos cálculos son teóricos y que la realidad de la sala puede desviarse de ellos debido a factores como puertas, ventanas, materiales de construcción y más. Finalmente, anima a los espectadores a descargar su marco de trabajo de tratamiento de estudio en casa, que les guiará a través de los diferentes pasos para tratar su sala de manera efectiva.

Transcripts
hey what's up it's jessica again from
acousticsinsider.com where i teach home
studio acoustic treatment techniques for
audio professionals but without all the
voodoo i want to revisit a topic uh that
comes up often and a very specific
question about this topic let's talk
about room ratios again but in
particular the golden ratio
because obviously that comes up a lot
still does is the golden ratio really
that good
when it comes to room ratios when
picking dimensions for your room
i thought i'd
test this theory a little bit by kind of
the more more modern standards and see
what that gives us
let's dig in so what i've got here are a
few of the sort of typical room ratio
recommendations
on the left
which i got mainly from
the master handbook of acoustics and on
top is the the golden ratio as well i've
added an example for each right because
the way this works
is that we always start with kind of the
room height
as the beginning of our calculation we
consider that as
sort of the unit height one and then we
multiply that
that number that actual number by a
certain factor
to get the ratios right so in the terms
of the golden ratio for example we start
with a room room height of one and then
a width of 1.6 times that height and
then 2.56
times the height to get the length of
the room right so i got an example here
of what that might look like for a
typical small room a typical home studio
with kind of a
about an eight-foot ceiling i'm doing
this in metric because it's just much
easier to kind of add the numbers into
the calculator uh in metric than
imperial um so just bear with me but
like basically this is eight feet and
the same concepts apply i just don't
want to work with fractions why why why
these stupid fractions with feet anyway
so we got the golden ratio
and then we've got a bunch of other ones
here we've got sep maya loudon and then
forkman and boner
boner yes i watch a lot of family guy um
so um
and i kind of picked out i calculated a
few examples that i just want to show
you there are a bunch of others but i
just want to give you an overview of how
the golden ratio compares to some of
these others by the most modern
standards or the most kind of recent
standards that we've got the recent
models that we've got okay
uh quick disclaimer obviously follow you
guys out there who are now thinking oh
god i have to optimize perfectly
optimize my room down to the fraction of
an inch
no you don't obviously this only works
in
square rooms
right the more your room deviates from a
perfect square the less this will work
okay so even slight angles will change
the actual frequencies at which you will
actually find room modes um the way the
room is constructed will change the
frequency and the the intensity the
amplitude at to which degree room was
actually built up right so all of this
is very very theoretical just keep that
in mind and that it only really applies
to
square rooms
when you don't have a square room
none of this really matters
okay so just keep that in mind so on the
right we've got our amarok room mode
calculator which you've seen me use
quite a few times already and i'll link
it in in the description as well it
basically takes
these actual
numbers so the actual dimensions you put
them in here and it calculates at which
frequencies you end up with the main
types of modes all right it does a few
things on top of that obviously it shows
us where these modes sit at which
frequency okay and it also gives us a
kind of a visual description
of what that room mode looks like in
that square room there's also
a
cross that it plots in terms of the bolt
area which maybe you've seen me talk
about in
my kind of very practical tutorial on
how to actually use this calculator to
size the dimensions of your particular
room i'll link it in the card
and then it gives us
this bonello graph which i'll talk about
more because it's kind of the most
recent i guess the most accurate
way to kind of predict
um how good ratios are
part of this
so the other part that you really need
to understand is that
optimizing room dimensions no matter
what
what
ratio you go for what kind of metric you
go by it doesn't stop you from having
big peaks and dips in the low end in an
untreated room right this just says
where the room modes sit yeah and if
they overlap for example but it doesn't
tell us uh or it doesn't it doesn't keep
these room modes from happening okay so
this is not a
optimizing room dimensions is not a way
to get rid of room modes optimizing room
dimensions is a way to ideally spread
them out evenly evenly make them not sit
on top of each other or have huge holes
and you get that even spread and
basically the way to think about it is
that it gives you a foundation
for good potentially good low end when
you go through the treatment process all
right that's that's all it is yeah
optimizing room dimensions is building
the a good foundation for a an even low
end okay
so
now let's let's dig in and look at some
of these ratios obviously the question
is
if we if we try and answer how good a
certain ratio is
what metric do we use
good by whose standards right
and so that's not an easy question to
answer yeah so i think the most the most
kind of
relevant one or the one that kind of
makes the most sense to me is really the
the boneless one uh basically bonelo
said
if you
divide the spectrum up into third octave
chunks
you want
the number of room modes in each chunk
to gradually go up as you increase as
you go up in frequency
ideally you want to go to go up if it
stays the same that's okay too right so
that's kind of all we're looking for
we're looking for
this number here to gradually increase
or at least stay the same
all right
and so with these numbers that i
calculated here for this golden ratio
room so 250 centimeters by 400 by 640.
turns out there's a big hole
right there yeah
so uh that already not so great yeah uh
if we look at kind of the older way to
analyze this which is a much simpler and
just as good to be honest way to do this
um
the bolt the ball area the cross doesn't
even end up in the bolt area you know so
this blob basically is a as a as a
region in in in
in the different
plots of uh or in the different
combinations of dimensions
if you if you kind of plot this if if
that if you plot that that cross
and it ends up inside this bot area you
basically have a basis for good
dimensions yeah and so even in this case
that doesn't end up where it's what's
supposed to be yeah so
um the golden ratio not so great at
least with these numbers that i picked
okay
that might change a little bit does it
change
i mean it scales it scales obviously in
frequency it scales in
pure dimension
uh
sort of numbers as in when we're talking
about actual lengths
and we're talking about how that maps to
notes
in the in music that's a different
question but um yeah let's not dive into
that hole any further um basically
right now it's not looking good for the
golden ratio
so let's go over to seppmeyer all right
so there's a bunch here that
that um everest lists in his book i
think there are more
but i basically only calculated this
first one because i wanted to look at
these other ones as well so here is the
next one 250 by 285 by 347.5
bolt
eh just on the edge bonello not looking
too bad
yeah
one other way to kind of
judge how good this actually is
is once once the bonnello is looking
good
we can look at a pile-ups so whether
there are room modes sitting on top of
each other right and and uh
down here this doesn't look too bad but
up here
there's a there's a kind of a pileup
happening here there's a pileup
happening here all that might might mean
that that area might be a little a
little tricky in the frequency range
obviously this is kind of
easily like way above 100 hertz so it
shouldn't be too difficult to treat this
with the treatment or to get control of
this with treatment but that's just
something to be aware of okay all right
so sapmyer in its first version not too
bad let's move on loudon in this first
one
so
250 by 350 by
4.75 at bonello again
that looks pretty good jumping over to
the bolt area right smack in the middle
not bad
and in terms of
pile ups maybe
one here just under 100 hertz a bunch of
stuff happening up here over here but
this is way above 100 hertz should be
relatively easily treated
so loudon
looking pretty good so far at least this
particular ratio
okay here's another one faulkman
let's look at this dude 250 times 375
times 625.
that's not looking good bolt just on the
edge but bonello not so much yeah we've
got two two steps
uh where the number actually increases
yeah so
this is not particularly good uh um at
least by boneless standards right and
we've got some pileups here again
pileups here yeah so uh yeah maybe you
wouldn't want to pick that one okay
let's go for boner boner
all right so here's boner
bolt looking good bonnello looking
pretty good
in terms of pile-ups
yeah this doesn't this doesn't look too
great
over here either yeah some pileups here
as well
yeah so this one although good by these
two metrics bolt and bonello if you we
actually look at where the room modes
end up um
maybe it's not the grade the the kind of
the the greatest ratio the best uh
option
okay so as a quick overview i think
that's uh pretty clear yeah the golden
ratio
at least by modern standards for room
ratios in this particular example
not so great your mileage might vary if
you mess around with these numbers
but
i probably wouldn't pick that as my
first choice i'd probably go with uh
with one of these other ones and just
check whether with what i've got
available uh they work out and then and
then maybe go with those right but again
a reminder don't obsess about this it's
not worth it yeah this is very very
theoretical in practice
your room's
actual room mode pattern will deviate
from this calculation quite a bit even
just windows doors
if you one wall is made from drywall if
your floor your ceiling is particularly
flimsy all this stuff has an impact on
the actual pattern and the the spread or
the the location of these actual room
modes and then these calculations become
kind of
pointless yeah so don't obsess about
this it's it's fun enough to check
what's going on
but then just kind of
pick something and then just move on or
just as a reminder if you are currently
in the process of treating your room or
you want to treat your room and you need
kind of a an overview of what it is
you're actually doing figure out in what
order to walk through the different
steps of treating your room i want you
to download my home studio treatment
framework at the link in the description
it's my five steps to treating a home
studio it's the same process that i go
through when i treat a home studio
it's the same process that i think you
should go through in order to not turn
in circles while you're moving through
this fairly complex topic right so make
sure you follow the steps in the home
studio treatment framework so that you
can
be sure that you're doing the right
thing at the right time obviously this
is part of that as well it's the first
step in the process analyzing the room
and there's a bit of context in there as
well and how to think about this
but again if you are in the process of
treating your home studio make sure you
download that at the link in the
description
okay that was a quick one a video about
the golden ratio
some more context into this whole topic
of picking room dimensions picking
ratios i hope you got something out of
it as always let's get back to trusting
our ears and having fun making music in
the studio i'll see you in the next
video
