Noise generation from leaking gas 1

[chemicalseddon]

Does anyone know calculation methods for the following?
a) Methods for estimating the noise generated by an un-ignited release of high pressure gas, eg we have a hole in a pipe and gas comes out how do we estimate the noise this generates
b) Methods for estimating the noise generated by an ignited release of gas, eg we have a hole in a pipe which releases flammable gas which then burns. Again how to estimate the noise generated - I guess this last one will be like a flare stack

chemicalseddon,
you should probably contact a Company providing NDE services.
As far as I remember from my Level 2 LT (Leak Testing) Operator training to EN 473 and ASNT-TC-1A standards, there is an acoustic emissions method and an Espert in that fied should easily answer your questions...
See, for example:
