It is due to pressure on the cold side.

And this may be causing an "O" ring on the non return valve or main cartridge to make the noise.
This can be cured by lubricating the "O" ring with some silicon grease, www.showerdoc.com/the-shower-doctor-silicone-grease-30ml-tub-mcsilicone , or replacing the "O" ring if it is damaged.
