Different products. Different listening conditions.

An app sound can signal a message, acknowledge a completed action or communicate a relevant change. Its value depends on how often it occurs and what the user is doing at the time.

We consider notification frequency, foreground and background use, platform behavior and user settings. Related sounds need a clear structure so people can distinguish events without unnecessary complexity.

Typical applications
Message notifications, completion feedback, selected errors, transaction confirmations and live-event updates.

Devices often communicate while the user is looking elsewhere. A completion tone, connection signal or status cue can provide useful information without requiring a glance at a display.

We consider the loudspeaker, enclosure, listening distance and surrounding noise. We also plan how a sound family remains recognizable across products with different acoustic capabilities.

Typical applications
Household appliances, speakers, headphones, smart home devices and connected accessories.

Mobility experiences span apps, shared vehicles, charging and in-vehicle interfaces. Sound can help users identify transitions and confirm important actions across that journey.

We distinguish everyday feedback from safety-related warnings and exterior vehicle sounds. Each category has its own design conditions and may involve specific regulatory requirements.

Typical applications
Booking and access feedback, charging status, connection cues, vehicle notifications and defined exterior sound concepts.

A medical sound needs a clearly defined role. Routine feedback, advisory information and alarms should be considered within the device's risk management and usability work.

We develop sound concepts with attention to the intended users, the clinical or home environment and competing signals. Applicable alarm requirements and evaluation responsibilities need to be established at the start of the project.

Typical applications
Status feedback, treatment completion, connection information and alarm concepts within an agreed development scope.

Industrial environments, checkout systems and public terminals create different demands on sound. Users may face background noise, repeated tasks or limited access to visual information.

We consider how messages are perceived, distinguished and supported by other feedback channels. Accessibility and safety requirements depend on the equipment and its use.

Typical applications
Payment terminals, kiosks, tools, production equipment and public interfaces.
