Measurements

It has taken me a while to figure out how to measure and interpret the vibrations. The vibration intensity and frequencies varies by location in the house. Also, there are limitations to what I am able to record with the data logger I have. 

 

Example Night 1 / Example Night 2

The best way to see when the vibrations occur is to look at time series data. Time series data shows just that, vibrations recorded over a period of time.

Week 1/4/2021

Here is a recent week of nightly measurements. Time series data shows just that, vibrations recorded over a period of time

 

 

Example Wave Form Analysis

This shows the vibration in acceleration versus frequency for a single direction. The image is the result of an analysis of 5 minutes of data recorded at the sampling frequency (raw), in this case 4,000 hz.
