Dear All

I'm trying to find answer to below 2 questions;

1. Is there any regulation/standard/code which define the noise level limitation of safety valves ?
In my project, all safety valve noise level is more than 150 dBA (for gas service). Client reject the noise level with reason of too high.

2. Does anybody know the calculation fomula of the noise level for the safety valves ?

I believe somebody can help me.

Safety valves (in particular I don't know)
Valves in general are limited to 80 DB (In north America)
