Are you passionate about audio and want to truly understand how your speakers perform? Do you dream of designing your own DIY loudspeakers or optimizing your existing sound system with scientific precision? If so, ‘Acoustics 201: Loudspeaker Measurements’ on Udemy is the course you’ve been waiting for.
This comprehensive course dives deep into the practical aspects of loudspeaker measurement, demystifying complex acoustic principles and making them accessible to enthusiasts and aspiring audio engineers alike. The primary focus is on learning to measure the frequency response of speaker drivers, complete loudspeakers, or even entire sound systems. The real magic here lies in the instructor’s ability to guide you through obtaining an anechoic response *without* the need for an expensive anechoic chamber. Through intuitive software and clever measurement techniques, you’ll be equipped to measure the full frequency bandwidth in the comfort of your own home – a feat that sounds intimidating but is made remarkably straightforward.
Beyond just frequency response, the course touches upon the essential electrical engineering aspects of audio. You’ll learn to measure impedance, generate impedance plots, and analyze electrical components like capacitors, inductors, and resistors. A particularly valuable module covers the measurement of Thiele/Small parameters for unknown speaker drivers, a crucial step for anyone serious about DIY speaker design.
While not a dedicated crossover design course, ‘Acoustics 201’ provides a fantastic foundation by teaching you how to generate FRD (Frequency Response Data) and ZMA (Impedance Data) files. These files are the bread and butter for crossover design software, and the course concludes with a practical demonstration of loading these files into such applications, allowing you to experiment with different crossover circuits and observe their impact.
Regarding equipment, the course is upfront about the necessities: a measurement microphone (like the miniDSP UMIK-1) and an impedance measurement device (such as the Dayton Audio DATS v2/v3). While these represent an initial investment, the course provides a detailed list with alternatives, including more budget-friendly options, ensuring you can tailor your setup to your needs.
The software used is Room EQ Wizard (REW), a powerful and, crucially, *free* acoustic measurement program. The instructor acknowledges REW’s limitations and provides a custom Excel spreadsheet to overcome them, offering a complete and accessible measurement package.
With regular updates, including added English subtitles and corrected measurement details, the instructor demonstrates a commitment to the course’s quality and user experience.
In summary, ‘Acoustics 201: Loudspeaker Measurements’ is an outstanding resource for anyone looking to move beyond guesswork and embrace data-driven audio setup and design. It bridges the gap between complex acoustics and practical application, empowering you with the knowledge and tools to truly understand and optimize your sound. Highly recommended!
