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

The best thing is that the results are visually visible and easy to understand using the loudness map.

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.

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.
