Simple tips to fix the acoustic problems of your room.
In this tutorial we’re going to explain how to fix the most simple acoustic problems a room may have.
How to improve the acoustic quality of your room.
Almost every sound improvement technique moves towards a goal: to eliminate reflections.
Reflections are nothing but altered versions of the initial signal, that are going to mix up the final result, eventually ruining the audio quality.
Standing waves are another major problem, but they are way too complex to explain for a basic tutorial.
From an acoustic point of view, corners are quite peculiar: if they’re empty, they may cause troubles.
You should try to cover them, for example using medium density mineral wool panels (do not choose them with density above 100 kg/m3).
Bare walls create reflections.
There are many ways you can cover them: fabric, composite mineral wool panels (one panel with density not above 50 kg/m3 along with another underlying panel with density between 70 & 80 kg/m3), foam rubber…
Your goal is to prevent frequencies to bounce between the walls.
Keep in mind that, the higher the frequencies, the lower the density of the cover material should be. We will show you in another article how to roughly calculate this ratio.
Don’t overdo, otherwise you’ll have an excessively dry room. Usually, it is advised to leave at least one wall without any treatment.
As well as walls, even the ceiling can create reflections.
Treatment methods are the same as wall ones.
Couches, armchairs, bookshelves… Anything that fills the room is able to improve its acoustics, dampening the sound waves and preventing them to frantically bounce off the walls, creating reflections.
As always, don’t overdo, otherwise you’ll have no room to move around.
Do not rely on your hearing alone: to properly understand which frequencies are causing troubles in your room, you should make use of scientific devices for your measurements.
For the brave ones, we’ll publish an article in which we’ll explain how to carry out a basic room analysis.
This tutorial is a brief guide aimed at solving some minor sound problems: in case of serious sound issues, the situation becomes extremely difficult, and the treatments required happen to be very expensive and intricate.
In the event that this tutorial is not sufficient to help you achieve a suitable room acoustics, our suggestion is to get in touch with an acoustic treatment specialist.
