## 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…

## Noise & Vibration Analysis: Back To Basics

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…

## How Do I Convert To Decibels?

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…)

## Sound, Vibration & Acoustics Digest #1

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…

## [Video] Exporting DATS datasets in non-linear format

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

## Exporting DATS datasets in non-linear format

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…)

## Why is the microphone pressure reference 2*10^-5 Pascals?

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…
