Every sound leaves an impression.
Make it intentional.
A confirmation can reassure. An alert can create urgency. A game cue can pull someone forward. DoReMiFo measures how people perceive these moments — and develops technology to help sound teams refine them with intent.
Same brief. Different impression.
Play the sound variants. Which one would you choose for the same moment?
Which one feels right?
Same brief. One version says everything's fine — the other sounds like an alarm.
Your team can hear a difference. Sound Perception Test shows whether listeners hear it consistently — and whether the evidence is strong enough to choose.
You have strong sound variants.
Now you need to choose.
DoReMiFo tests your sound variants with independent listeners and measures how they are perceived in the context that matters to you.
You bring the sounds and the decision you need to make. We design the listening experiment, recruit participants, analyse the evidence and give you a result your team can act on.
- How each sound lands — tone, energy and the meaning listeners read into it
- Direct comparison between variants
- Intended meaning: clearly recognised or ambiguous — how each sound reads against the event it has to signal
- Decision Confidence — the strength of evidence behind the call
- One of three calls: Ship, Revise, or Evidence inconclusive
A clear choice when the evidence supports one.
A clear limit when it doesn't.
Send us your sounds and the decision you need to make.
We design and run the listening test.
You receive the evidence, interpretation and recommendation.
Measure. Predict. Refine.
A research and technology path, not three finished products. Measure is available today — Predict and Refine are where the lab is heading.
Measure
Measure how people perceive real sound variants through controlled listening experiments.
Predict
Develop models that estimate how new sounds may be perceived — with uncertainty and clear limits on where the prediction can be trusted.
Refine
Build tools that help sound designers move a sound toward a perceptual goal while keeping creative judgment in human hands.
Built for the sounds that shape everyday interaction.
Product and UI sounds
The small sounds that confirm, deny, or guide an action.
Notifications, confirmations and alerts
Moments that need the right urgency — not just more of it.
Game sound effects
Feedback that shapes how an action feels, round after round.
HMI and device sounds
Interface sound for physical products, appliances and vehicles.
Short sonic branding assets
A few seconds of sound that carry an identity.
A research lab, not a black box.
DoReMiFo is a research lab: commercial listening studies (DoReMiFo s.r.o.) and academic research (HAMU Prague, SGS grant) inform each other while remaining separately funded and governed.
Using client data for further research is never automatic — it depends on the agreement in place for that engagement.
Rigorous about what we know.
Explicit about what we don't.
If the evidence does not support a meaningful difference, we say so.
