Acoustics 201 : Loudspeaker measurements from Udemy

Learn how to measure frequency response

The first thing you will learn from this course is to measure the frequency response of a certain speaker driver, loudspeaker or sound system. The difficult part is to get an anechoic response without an anechoic chamber. Using different measuring techniques and with the help of intuitive software, you will learn how to measure the full frequency bandwidth anechoically in your own living room. This will help you set up your audio system using measured data, or it can be used to design crossovers for your particular DIY loudspeaker.

A little bit of electrical engineering

A sound system is a combination of both acoustical and electrical parts. You will also learn how to measure impedance and create impedance plots. Measure different electrical components like capacitors, inductors and resistors. Also, if you have an unknown speaker driver you will learn how to measure the Thiele / Small parameters without much fuss.

Dip your feet into crossover design

While this course will not teach you how to design a crossover, it will show you how to create FRD and ZMA files. These are frequency response and impedance files which are used in crossover design apps. At the end of the course I will show you how to load these files into such program, and tryout different circuits and see how adding crossover components behave. A comprehensive course about crossovers will be released in the near future.

Do I need certain equipment?

Yes, you will need 2 core pieces of gear :

A measurement microphone (like miniDSP UMIK-1).
A device for measuring impedance (like Dayton Audio DATS v2 (recently released v3 as of 2020).

These are roughly 100$ each, but you will get a more comprehensive list of the equipment needed inside the course. With alternatives that you can buy, or more cheaper options. Also, some accessories that will make your life easier are included in the list.

Software option

For the different acoustical measurements we are going to use Room EQ Wizard (or REW). This is a free to use software. Usually, acoustics software are quite expensive and difficult to follow. However, REW is free and quite intuitive to use. Pretty much a complete package. It only misses one function, which I consider important. Don't worry, we're are not going to step up to those complicated application. I devised an Excel spreadsheet which handles this shortcoming. You will find the spreadsheet inside the course.

Reviews summary

Practical loudspeaker measurement techniques

According to students, this course offers a practical, hands-on approach to measuring loudspeaker performance. Learners appreciate the detailed guidance on using key software like REW and hardware like the miniDSP UMIK-1 and Dayton Audio DATS. A major highlight is learning techniques to achieve anechoic-like measurement results at home. While praised for its focus on generating necessary measurement data (FRD, ZMA files), students note it covers measurement for crossover design applications rather than teaching the design process itself. Be aware that owning specific required equipment is essential for following along.

Focuses on measurement files, not crossover design.

"It clearly teaches you how to create the necessary FRD/ZMA files for design software..."

"...but don't expect to learn actual crossover circuit design here; it's explicitly measurement focused."

"The course successfully prepares you with the data needed for design applications."

Detailed guidance on using REW and DATS.

"The setup instructions for REW with the UMIK-1 were crucial for getting started correctly."

"Understanding how to use DATS v2 for Thiele/Small parameters was made clear."

"Applying the techniques with REW felt very practical and directly applicable."

"The demonstrations showed me exactly what to do step-by-step to get useful data."

Methods to get anechoic-like data at home.

"Learning techniques to get anechoic results in a normal room is perhaps the best part of the course."

"The splicing technique for combining near and far field measurements was a revelation."

"I can now make meaningful frequency response measurements in my own listening space thanks to these methods."

Need equipment and some prior audio/EE knowledge.

"You definitely need to have the specific measurement mic and the DATS device to follow along effectively."

"The course assumes you know a little bit about basic electronics or acoustics beforehand."

"Might be a bit tough if you are completely new to audio engineering concepts."
