Calculating a weighted acceleration value for evaluating a ride comfort of vehicle . how can i convert my PSD signal input in to 1/3 octave rms value?

16 February 2016 1 9K Report

kindly suggest some matlab program or any mathematical formalism

Please see an example of the 1/3 octave bank filter design and other usefull tools.

Also I highly recommend you to look at the Brüel&Kjaer Library offered excellent research articles regarding the noise and vibration measurement and processing.
