  exactly what Bally said fixed it for me. The sound is subjective and will depend on humidity etc. That said, I also regularly use the Gummipfledge which definitely helps maintaining the seals. Hopefully, it’ll stop the door seals sticking in freezing conditions which was a problem on my Copen but, touch wood, not on the Mazda.   

within this link are other links. There is a good chance that you will find an answer.
