Concept for good sounding rooms

To achieve highest quality level of sound reproduction, room acoustics must meet certain criteria.

The room is treated, to achieve those desired acoustic properties, using a combination of absorption, reflective surfaces and diffusion.

Acoustic treatment can be built into walls and surfaces, or modular acoustic modules mounted on walls. Visual appearance can be tailored to suit different interior styles.

The result is predictable, and all rooms can be fixed.

This Acoustics Service is a guide to do this in your room. You get to see what it takes to fix it. And help to get it built and implemented.

What is achieved

Better sound

If the room had no treatment and mostly bare walls, little furniture, there will be a huge and dramatic difference. For rooms that sort of works already, the improvement will still be large.

When the acoustic signature of the listening room is removed, you are left with the room and reverb from the recording. Different albums and music will sound different.

Tonality improves when decay is linear across the frequency range, the original timbre of instruments can now be heard.

Clarity is improved when masking reverb from the room is removed.

Removal of early reflections gives a presentation with precise imaging and a distinct, realistic character to the sound.

Everything improves, perhaps one exception; any faults in the sound system will now reveal itself, when masking from room contributions disappear.

Pleasant to be in the room

The comforting atmosphere is immediately noticed when you enter the room. Normal conversation, watching the news, everything with sound benefits from nice acoustics.

Measurable difference

Is there a measurable difference between a typical vs treated room? Yes, indeed.

The frequency response does not tell which room is better. Both graphs show some deviation, but it is not obvious that one room is better:

Frequency reponse rather similar

But when we look at decay, we easily see a huge difference:

Treated room decay is dry Typical room decay is not damped

Treated room first left, typical room right.

The treated room has much larger early attenuation. Differences are found mainly in the time domain, and when we know how to look, we see it.

Who is this for

Anyone who has a small room - small means all normal rooms in a house - and reproduce sound in there - music, movies, other media content with sound. For pure entertainment, or professional.

Requirements will be very different for a multi-purpose living room, compared to a dedicated sound studio. But they share the same acoustic challenges, and the same methods can be applied to achieve the best possible sound, inside the limits of what is reasonable to do from a practical perspective.

Guiding you through your room acoustic treatment project

We fix your room.

We have a dialog about your room and discuss solutions.

Acoustic measurements are not necessary, but recommended at later stages in the build process.
