Title
Measurement of Noise from Fired Process Heaters
American Petroleum Institute
Publication Date:

Scope:
1.3 Scope
This test procedure defines (a) the geometrical envelope which is recommended for near-field noise measurement and (b) the analytical methods applicable for computational analysis of the total sound-power level of a fired heater.
It is intended for use with direct-fired equipment and associated ancillaries which might reasonably be expected to be installed in a petroleum process plant. It is based on the use of a portable precision sound-level meter, an octave band filter, microphone, and compatible vibration transducer with signal conditioning equipment. The metric system of units is used in this recommended practice because it is the universally accepted system.
