Not great news from the trial, got an e-mail from them just before. They won't be publishing due to some deviations from the protocol. This is both good and bad; bad that we have to wait longer to know how effective it could be, good to see that the trial was fully reviewed and it is a robust process to make sure the results are completely accurate.
The official statement is:
"Acoustic CR® Neuromodulation is a treatment for chronic tonal tinnitus. In 2012, The Tinnitus Clinic Ltd funded a 100 participant Randomised Controlled Double Blind Trial to establish the efficacy of this treatment under independent controlled conditions.
The trial was undertaken at Nottingham Hearing Biomedical Research Unit and the Ear Institute at University College London and was sponsored by Nottingham University Hospitals NHS Trust.
The first results of the trial were expected in September 2013. Review of the trial has, however, concluded that there have been deviations from the trial protocol and that the results cannot be regarded as scientifically robust. It is therefore with regret that all the parties have concluded that the results of the trial cannot be published with confidence.
Nottingham University Hospitals NHS Trust and The Tinnitus Clinic are discussing a new trial on Acoustic CR Neuromodulation which they hope will commence in the near future. NHBRU, Nottingham University Hospitals NHS Trust and The Tinnitus Clinic are very grateful for the time and effort of the participants of the original trial"
