Architecture is seen. Interiors are photographed. Lighting is presented.

Sound is assumed.

In most projects, sound enters last. When the space is already finished. When walls are in place. When problems can no longer be solved structurally.

This is a mistake that costs years.

Silence doesn’t exist

Many spaces want “silence.” A calm atmosphere. Absence of noise.

But what they actually want isn’t the absence of sound. It’s the absence of discomfort.

A space without sound structure amplifies everything it should mask. This isn’t silence — it’s an acoustic vacuum.

A space without sound structure:

  • Amplifies footsteps — every step echoes
  • Highlights conversations — the guest hears the neighboring table
  • Makes every noise invasive — phone, plate, chair

This isn’t silence. It’s an acoustic vacuum that amplifies everything it should mask.

Materials shape sound

Architectural materials don’t just serve aesthetics. They define how a space will sound.

Hard surfaces
Glass, concrete, metal

Reflect sound, amplify it, sharpen it

Soft surfaces
Textiles, wood, upholstery

Absorb sound, soften it, calm the space

Hard surfaces — glass, concrete, metal:

Reflect sound. Amplify it. Sharpen it.

In a space with many hard surfaces, sound “bounces” from wall to wall. Conversations mix. Noise grows exponentially with the number of guests.

Soft surfaces — textiles, wood, upholstery:

Absorb sound. Soften it. Calm the space.

In a space with sufficient absorption, sound “dies” before it becomes a problem. Conversations stay private. Noise doesn’t accumulate.

The most common mistake

The most common mistake in space design isn’t bad acoustics.

The most common mistake is separating acoustics from experience.

Typical scenario:

  1. The space is designed visually. Architect, interior designer, investor — everyone focuses on how the space looks.
  2. Acoustics are handled technically. An acoustician arrives at the end, measures reverb, proposes panels.
  3. Music is added “to fix things.” Someone plays something to mask problems that architecture didn’t solve.

This doesn’t create an experience. This creates compromise — a series of patches that never function as a whole.

Sound as material

If we accept that sound is:

  • Present constantly — you can’t turn it off
  • Inevitable — the space will sound some way, the question is how
  • Emotionally powerful — it affects how the guest feels

Then we must treat it as material.

Technical acoustics vs. acoustic architecture

There’s a difference between two approaches.

Technical acoustics
Measurable parameters

How many decibels? How much reverb? How much absorption?

Acoustic architecture
Guest experience

How do people feel while here?

Technical acoustics asks:

How many decibels? How much reverb? How much absorption?

These are important questions. They give measurable answers. They can be specified and verified.

Acoustic architecture asks:

How do people feel while here?

This is a harder question. The answer isn’t a number. But it’s more relevant to the guest experience.

Both approaches are needed. But only one creates the experience.

Why sound can’t be “added later”

When sound is addressed after the fact, options are limited.

Walls are already in place. Materials are chosen. The ceiling is defined.

An acoustician can add absorption panels. Can propose rugs. Can try to mitigate problems.

That’s why the best spaces think about sound at the concept stage:

  • Align materials with acoustic goals. Don’t choose materials only visually.
  • Plan zones acoustically, not just functionally. Where will it be loud? Where quiet? How to separate them?
  • Design transitions. The space between zones is as important as the zones themselves.

The role of music

In this context, music has a specific role.

Music doesn’t “fix” a space. It doesn’t mask bad decisions. It doesn’t compensate for mistakes.

Music uses architecture. It doesn’t fight against it. This is the difference between a patch and infrastructure.

In a well-designed space, music:

  • Stabilizes — fills gaps, evens out the soundscape
  • Connects — creates continuity between zones
  • Provides rhythm — follows the dynamics of the day and activity

Why this is becoming decisive

As design differences shrink — as spaces become visually more similar — the advantage shifts.

Not to appearance. Everyone can copy appearance.

To quality of stay.

Remembered
Guest experience

But remembered and affects return

The guest who feels comfortable in a space — can’t explain why. But returns.

The guest who feels uncomfortable — also can’t explain. But doesn’t return.

Practical implications

For architects and designers

  • Include sound in early project phases. Not as an addition, but as a parameter.
  • Talk to acousticians before materials are chosen. Not after.
  • Think about experience, not just technical specifications.

For investors and operators

  • Require acoustic analysis during the project phase. Don’t wait for problems to manifest.
  • Budget for sound like you do for lighting. It’s not optional — it’s an element.
  • Understand that the space will sound some way. The question is whether you control it or not.

The invisible wall

Sound isn’t an addition to space. It’s its invisible wall.

Walls define what’s seen. Sound defines what’s felt.

And while walls are drawn, sound must be planned.

A space that sounds right — doesn’t need explanation. It’s felt.


What is acoustic architecture?

Acoustic architecture is an approach to space design that treats sound as a structural element — equally important as materials, lighting, or layout. Unlike technical acoustics that measures parameters, acoustic architecture focuses on how people feel in a space.

Why can’t sound be added later?

When a space is already built, walls in place, and materials chosen, acoustic solutions are limited to patches — absorption panels, rugs, curtains. Structural solutions are no longer possible, resulting in a more expensive and weaker outcome.

How do materials affect acoustics?

Hard surfaces (glass, concrete, metal) reflect sound and amplify noise. Soft surfaces (textiles, wood, upholstery) absorb sound and calm the space. The combination and arrangement of materials determines how a space will sound.

What’s the role of music in acoustic architecture?

Music doesn’t “fix” bad acoustic decisions. In a well-designed space, music stabilizes the soundscape, connects zones, and follows the rhythm of the day. Music uses architecture — it doesn’t fight against it.
