Hi Hossam. I cannot diagnose regulators over the internet, so this is only a suggestion. The regulator must be looked at in person by a qualified technician in order to properly diagnose or work on Mares regulators. Some people describe a sound like similar to a honk or vibration. This could be a result of how the airflow is travelling over the 2nd stage LP Spring. I recommend taking this to an authorized Mares Lab technician and have them take a look. If we are talking about the same thing, it is not a performance related issue, is just a harmonic that occurs when air travels over the spring. Most of the time this can be solved by simply turning the spring upside down, or replacing it. Again, I preface this with my post is only a suggestion to have a trained tech look at it. Do not try to service this on your own. I hope this helps.
