Manage your terminal's sonic experience.

So everyone can enjoy the freedom of travel.


Clashing announcements, echoey spaces, and distorted communication prevent disabled customers from using devices, keeping up with information, and navigating your terminals.

Accessibility coordinators.

Remove barriers to travel with sensory-friendly environments. Identify and address noise, acoustics, and sound that restrict the use of assistive devices and prevent people from using your terminals. Use these insights to inform design and accessibility plans for all your disabled passengers.

Information managers.

Ensure clear and understandable audio information and way finding by regulating noise levels, managing equipment use, and optimizing acoustics. Use passenger data analysis to anticipate where passenger flow affects information clarity and the experience of people with disabilities in your dynamic terminal environments.

Start with an assessment.

Video walkthrough of your space.

Quickly validate concerns about noise and sound impact with our affordable service, to guide your next steps.

Priority area test & diagnosis.

Target a specific area that you need to address now. Move forward quickly with practical recommendations.

Comprehensive user journey assessment.

We collaborate with your disabled passengers to identify barriers they encounter and how to remove them.

Sonic experience design.

1. ADA compliance.
Identify and remove barriers to access caused by sensory overload and interference with peoples' assistive devices.
2. Clear communication for safety.
Manage the factors such as background noise, unclear announcements, and equipment distortion that affect navigation, safety, and emergency management.
3. Design systems for accessibility.
Optimize passenger and disruption management systems to prevent the overwhelming noise and passenger buildup that block access to information.

The disabling effect of noise.

For many, the noise is too much. So they just won't come.


Reduce cognitive load caused by noise and rapid announcements for people with dyslexia, sensory processing and cognitive disabilities, and autism.


Minimize interference with the real-time spatial, sonic cues people depend on to orient themselves, locate landmarks, and stay safe while using your navigation apps.


Realize your sensory room's full value by taking control of the triggering, over-stimulating environments people have to return to.

Unmanaged sound affects peoples' assistive devices.

Passenger management.

Congestion . Background noise.

Passenger build up due to busy flights and service disruptions.

Hearing aids.

Background noise . Acoustics

Hearing aids amplify background noise and reverberation, masking announcements.

Speech generators.

Background noise . Acoustics

Background noise and reverberant ticketing and help desks reduce audibility for staff and passengers.

Hearing loops.

Equipment . Announcer clarity

Equipment volume and distortion.

PA announcements.

Announcers speaking too quickly or close to microphones and equipment settings that affect clarity.

Information kiosks.

High-traffic environments interfere with audibility.


Improve information clarity and streamline passenger flow to craft a welcoming space for all.

Start small to have the biggest impact.

To kickstart your accessibility improvements focus on one area that will have the biggest impact.

Understand how your systems, environments, technologies, and behavior interact and affect each other. Uncover the barriers and opportunities these relationships create.

Gain valuable insights and test solutions to build momentum for your accessibility initiatives before scaling up — all without being overwhelmed by the scale of terminal network.

We help you —

1. Pinpoint your friction points and where to start.

We collaborate with real users on their journey to identify barriers so you can decide where you'll have the greatest impact.

2. Solve the problem.

Isolate the parts of your systems, environment, and technologies causing the barriers and fix them with evidence-based testing and user feedback.

3. Build sound management guidelines.

We create guidelines for you to ensure consistent and correct implementation of your assistive audio assets across all your platforms and future services.

Start with —

Turning everything down.


Test and adjust settings for technologies like hearing loops and public address systems to optimize clarity and intelligibility.


Provide workshops to improve enunciation, pacing, and microphone technique for clearer announcements.


Assess acoustics and speaker placement to minimize echoes and improve announcement clarity. Solutions include locating speakers closer to passengers and acoustic treatment.


Identify and manage sources of background noise like music and advertising. Implement practical guidelines for managing volume to minimize their impact on your communication.


Evaluate the impact of passenger flow and congestion on noise levels and information. Implement congestion-reducing strategies such as optimizing queuing systems and layout and redirecting foot traffic.


Conduct regular reviews and gather passenger feedback for ongoing improvements beyond ADA and accessibility standards.


Situations like service disruption and times of high traffic change crowd behavior, sensory stimulation, information clarity, and the ability to use assistive audio tools.

Use your passenger management data to predict how these situations affect people who're disabled.

Then, adapt your audio information design to match peoples' cognitive, sensory, and access needs.


Focus on people's goals, not their disability.
Ask, "What gets in their way?"


Map your customer journey.
Ask, "What helps you find your way?"

Just thinking about dealing with stations and airports is exhausting. We stopped using them.

Title II - Public Services: Effective Communication. A public entity shall take appropriate steps to ensure that communications with applicants, participants, members of the public, and companions with disabilities are as effective as communications with others.
Title III - Public Accommodations and Commercial Facilities. No individual shall be discriminated against on the basis of disability in the full and equal enjoyment of the goods, services, facilities, privileges, advantages, or accommodations of any place of public accommodation by any person who owns, leases (or leases to), or operates a place of public accommodation.

Have you asked?

Don't risk being non-ADA compliant by overlooking safety, access, and communication barriers caused by noise, passenger management, or acoustics. Take the proactive step to ensure inclusivity for all people affected by sensory sensitivities.

Talk to us about how to ask your Accessibility Advisory Committee to identify accessibility barriers created by noise and sound.

We'll guide you through the process so everyone can freely use your spaces.

"In a world not designed by them, Marcel creates platforms with people with disabilities so they can design their own experiences."

Carmen Madisson . Boilover Inclusive Performance Ensemble. Sunbury Cobaw Community Health.

"Not only did Marcel break down what was working and not working in terms of interfaces and the responsiveness and character of sounds, he explored how they hindered or helped them achieve their goals."

Wendy O'Neil . Art Centre, Melbourne.

"Marcel was indispensable to us and the success of the project, with that rare combination of practical know-how, a hard-work ethic, and inspired creative vision.''
