1. Is Sono suitable for all types of tinnitus?

Yes, Sono is CE certified and approved as a Class IIa medical device for for all kinds of tinnitus, including subjective tinnitus, objective tinnitus, pulsatile and somatic tinnitus. You should have had a diagnosis of tinnitus from your doctor or audiologist to rule out certain causes.

2. Do I need a prescription from my doctor or audiologist to use Sono?

No, you do not need a prescription to use Cleanhearing Sono, but you should have a diagnosis of tinnitus from  a doctor or audiologist. Tinnitus is rarely related to a serious medical condition but it does need to be checked for underlying causes. Please also check our list of contraindications. and discuss any questions with your doctor.

3. Is Sono contraindicated for any conditions?

Sono is contraindicated for certain conditions. Please see the list of conditions here. If in doubt, please consult your doctor.

4. Will Sono work for everyone?

Results are not guaranteed for all users. Based on research on pulsed electromagnetic stimulation for tinnitus and our customer feedback, we would expect between 45-60 percent of Sono users to see improvement in their tinnitus condition when using Sono regularly according to the the guidance for use. Typically, better results might be expected in tinnitus of shorter duration (under 5 years) though positive results have also been reported by Sono users with tinnitus of longer duration (10 years plus). 

Our rental packages and satisfaction guarantee are provided so that users can trial Sono without committing to the full purchase price. Our team is also on hand to assist with any enquiries, and to ensure you are using your Sono device to best effect.

5. Have you done any clinical trials?

As a startup company, we are excited that our first clinical trial is prepared and approved to run at a leading medical school in the US, hopefully within the next 12 months. The science behind Sono has been thoroughly investigated in many other peer reviewed studies, some of which you can find here.  We will be updating our mailing list and website as soon as we have further news about our own clinical study. 

6. Can I combine Sono with other treatments?

Sono works as a standalone device for electromagnetic therapy but can also be combined with other therapies, such as notched music.  If you are currently undergoing other tinnitus therapy, please consult your doctor or audiologist to find out if Sono is compatible with your existing treatment plan.

7. How will I know if the therapy is working?

Any unusual change in symptoms can be a sign that the therapy is starting to work. This might include a change in tinnitus pitch or intensity, or short periods of time when your tinnitus is quieter or absent. In some cases, relief can be very gradual, so you may not notice it immediately.

8. How soon can I expect to feel results?

This can vary greatly between different patients. While some users report significant results within the first two weeks – or even the first few days – of treatment, typically results are seen between 2-4 months of regular use. For some users, it may take longer than this. For best results, apply therapy regularly as described in your user manual while relaxing comfortably at home.

9. My tinnitus has improved, but is there a chance that it will come back again?

Because tinnitus can be triggered by so many different factors such as health, stress or medication, a future recurrence is not impossible but it is certainly not inevitable and relief should be long term. If you know what caused your tinnitus or made it worse, your doctor or audiologist will be able to advise you on how to minimise your exposure to potential triggers, and on what other action you can take to reduce the chances of your tinnitus recurring. Some users who have seen success with Sono choose to continue using it on a reduced ‘maintenance’ schedule to reduce the chances of their tinnitus recurring, or for related benefits such as improved sleep and relaxation. 

10. Are there any side effects?

For a small number of users, the sudden stimulation can cause mild early effects such as headache or muscle ache, which should resolve within 2-10 days as treatment continues. Starting your therapy at the 5-minute setting and building it up slowly as recommended in the user manual should minimize the chance of any such effects.

No adverse events have been recorded for the application of pulsed electromagnetic stimulation for tinnitus, so you should not experience serious discomfort. If you have any symptoms of concern, please stop using Sono immediately and contact your doctor to rule out other causes.

11. Is it possible for my tinnitus to feel worse when using Sono?

A small minority of users may experience temporary aggravation due to the sudden stimulation, resolving within a few days as treatment continues. To ensure a comfortable start for all users, you are recommended to start using Sono at 5-minute settings twice per day and build up slowly to the 20-minute setting twice per day over a period of 2-3 weeks to avoid the likelihood of any discomfort.

If you are ever concerned about any changes in your tinnitus condition, please consult your doctor to rule out other causes.

12. What happens if I miss a few treatments, or can't manage twenty minutes twice a day every day?

You can adjust the number and duration of your treatments according to your schedule, though you should try as far as possible to maintain regular therapies. Don’t worry if you miss a few sessions. Just try to return to a regular schedule as soon as you can. You can still expect results with shorter or less frequent treatments, but progress may be a little slower.
