The main program is Main_sound_and_vibs.m. Several metrics are for each of sound, hand arm vibrations, whole body vibrations, and motion sickness. Main_sound_and_vibs calls the primary dependent function
"Continuous_Sound_and_Vibrations_Analysis" which contains the switch statement controlling the data flow.

This program calculates metrics for continuous sound and vibrations. Sound metrics include: peaks, Leq, LeqA, LeqC, kurtosis, third octave band peaks and levels, and more.

Vibration metrics for hand-arm include: arms, armq, Dy, peak, crest factor, kurtosis, third octave band levels and peaks, and more.

Vibration metrics for whole-body include: arms, armq, VDV, MSDV, crest factor, kurtosis, third octave band levels and peaks, and more.

The vibration metrics except for the third octave bands are calculated using both the weighted and unweighted filters.

This program prompts the user for all of the inputs to the Continuous_Sound_and_Vibrations_Analysis.m program.

The user selects either matlab or wav files to analyze for sound and vibrations. There are a series of prompts for output filenames, formating of output images of the figures, and the Name of the device under test (Tool Name).

A welcome and powerful tool. Using MATLAB 7.12 but having problems with concatenating arrays

metrics_buf =

line 1401 in Continuous_Sound_and_Vibrations_Analysis.m

Looking forward to performing interesting analyses!

Hi Edward,
I am working on suspension system.
Can I use this program for VDV calculations of quarter car suspension system?


Seems to do the job. Good effort.

Estoy empezando a investigar sobre el analisis de vibraciones en maquinas rotativas, me interesa las cosas que haces, voy a analizar tus programas y si puedes apoyarme en algo, ahi te comento, gracias

good job!
