As part of its expansion, Mayfair Developments reveals the new visual identity of the ØREBLUE® method.



Since 2011, Mayfair Developments SAS has given itself a mission to treat patients suffering from tinnitus and noise hypersensitivity.

On the strength of the excellent results obtained with the method Oreblue®, Mayfair Development SAS initiates the medical project Nømad Treat®.

Our purpose, to develop a  travelling medical device including the method Oreblue® for the caring at home for patients suffering from tinnitus and noise hypersensitivity.

The progress of the research phases and the technological and medical developments presage the availability of Nømad Treat® on the horizon 2023.



Professor Gérhard Hesse, ENT doctor in Germany and Tinnitus specialist, alerted on the white noise for hearing.

The white noise stimulus would be ineffective in fighting  Tinnitus  and might, even at low intensity, damage the auditory system.

These comments corroborate patients complaining of an increase in their symptoms of tinnitus or hyperacusis after the use of white noise generators.

I have myself enumerated, in the course of numerous anamnesis conducted with my patients, similar facts to those evoked by Professor Hesser that I have privileged, among other clinical and acoustic virtues, using a music base to develop my therapeutic protocol : ØREBLUE®
