What Are dB, Noise Floor & Dynamic Range?
We are often asked what noise floor & dynamic range actually are. Most engineers are probably familiar with or have come across the decibel or dB as a unit of…

Sometimes it doesn't hurt to revisit some of the basic building blocks that form the foundation of what we do. And so we have gathered together a few of our…
Much confusion revolves around linear and non-linear numbers. The following outlines the mathematical process to convert from a number expressed in dB to a linear quantity. How do we convert to decibels and back again? (more…)
This is the first in a (hopefully) regular series of posts containing interesting & unusual sound & vibration stories that we have discovered around the web. We hope you enjoy…
To complement our recent post on Exporting DATS datasets in non-linear format here is James Wren demonstrating the method. https://www.youtube.com/watch?v=sh6Q3FwjtR4
The following tutorial shows in detail how to use Prosig DATS to export data in a non-linear format.
DATS stores all data in linear format. When you export data you are exporting the raw stored data. Therefore, to export data in a non-linear fashion we must convert the data to non-linear scale (dB for our example) and then export to the desired format, in this case CSV. (more…)
This seemingly simple question is actually quite fundamental. To answer the question we need to consider sound intensity. Now sound intensity is defined as “the average rate of flow of…
