balancing loudness
for the perfect fit
Work with revoloud to ensure that your customers can enjoy the best possible hearing experience.
The challenge of fitting hearing aids
Normalize loudness perception
The most common complaint of people with hearing aids is an inappropriate perception of loudness after the initial fitting. As a hearing aid specialist, you are faced with the task of understanding your customers' descriptions and translating them into amplification changes so that loud sounds do not disturb and soft speech does not remain unintelligible.
But how?
Measure & visualize loudness perception with revoloud
Your experience + revoloud
With revoloud you can measure and check the individual loudness perception of your customers.
The best thing is that the results are visually visible and easy to understand using the loudness map.
revoloud gives you the opportunity to respond optimally to individual needs, make more precise amplification settings and offer your customers the best individual solution.
NEW: With our new feature, you now have the option of measuring individual areas with revoloud . For you, this means even faster results after fine adjustment and therefore less stress for your customers.

With revoloud , we reach our goal much faster. The first fine adjustment is often enough to satisfy the customer. This saves us and our customers valuable time!

The individual hearing sensation, which is often difficult to put into words, is made visible using the loudness map. This allows us to take the customer along in the fitting process right from the start.

"revoloud" makes work much easier! Where before there was only a hunch and fog, now there is knowledge and clarity. I can no longer imagine my fitting routine without "revoloud".

With revoloud, even demanding customers can be convinced quite quickly that their hearing aids are well adjusted. And that reassures me too!

The loudness map is self-explanatory and it is easy to see where changes to the settings are necessary.

And this is how it works:
Presentation of natural signals
The customer is presented with 60 natural signals via a loudspeaker. Twelve signal categories are used, which are made up of two dimensions: test level and frequency range . The test level is divided into "quiet", "medium" and "loud". The frequency range is divided into "low", "mid", "high" and "broadband".
Evaluation of loudness perception
The customer rates the individually perceived loudness of the signals on a 11-point scale. This ranges from "not heard" to "extremely loud". Each signal can be repeated once by the customer.
Presentation of the results
Once the measurement has been completed, the result is displayed in the form of a loudness map, which uses different colors to describe the loudness perception in the 12 signal categories compared to people with normal hearing. For a barrier-free view, additional symbols can be switched on to represent the loudness perception.
Details on the presentation and development of revoloud can be found in the scientific publication:

System requirements
The measuring computer on which revoloud is to be installed requires an internet connection for online calibration and for communication with the license server.
The tablet for customer input, on which the revoloud runs, must be able to connect to the computer via Wi-Fi. We recommend using a tablet with a screen size of at least 10.1 inches.
Current version

FAQs
How long does a revoloud measurement take?
With revoloud, you get well-founded results in just six minutes. This means that fitting problems are often identified and rectified at the first appointment - quickly, precisely and efficiently.
Does the software also work on tablets?
The revoloud software is typically installed on a Windows measurement computer. The tablet used by the customer to enter the response only needs to provide Wi-Fi and a browser. This means that an Android, iOS or Windows tablet can be used.
Do I have to have an online connection for the measurement?
An online connection to the license server is required when starting the software. You can also retrieve results from the test history with an offline connection.
Can I deactivate the license on one computer and activate it on another?
A product key can be used at one measuring station at a time. If you want to change your measuring station, you can deactivate your product key on the computer of the old measuring station and activate it on the computer of the new measuring station.
In this case, please contact our support so that a new online calibration can be carried out for the new measuring station.
You can reach us by phone at: +49 441 2172-122 or by e-mail at: support@revoloud.de
The revoloud subscription includes one recalibration per year. No product key is required for a pure viewing station (e.g. consulting room or reception). In this case, the revoloud software can be installed without a product key.
Is revoloud compatible with NOAH?
Yes, revoloud is designed for use with NOAH. You can therefore save and retrieve the revoloud in your NOAH database.
Can I view the measurement results from any computer?
As long as all computers are connected to the same NOAH database, you can view the results on all measuring stations and viewing stations.
