If you’re an audio enthusiast or a budding acoustical engineer, the Coursera course ‘Acoustics 201: Loudspeaker measurements’ is an invaluable resource that bridges theoretical knowledge and practical skills. This course focuses on teaching you how to measure the frequency response of various sound systems, including loudspeakers and drivers, without the need for anechoic chambers. Using intuitive software like Room EQ Wizard (REW) and affordable measurement equipment, you’ll learn to obtain accurate anechoic responses right in your living room, making high-quality sound measurement accessible and cost-effective.
One of the standout features of this course is its integration of electrical engineering fundamentals. You’ll get hands-on experience measuring impedance and creating impedance plots, as well as testing various electronic components such as capacitors, inductors, and resistors. Additionally, the course guides you through measuring Thiele/Small parameters of unknown speaker drivers, a crucial step in speaker design and analysis.
While the course does not delve into crossover design, it introduces essential concepts by teaching you how to generate and interpret FRD and ZMA files—key tools in crossover development. The final sections demonstrate how to load these files into crossover simulation software, enabling you to experiment with different circuit configurations and observe their effects.
Prerequisites include basic electrical knowledge and some affordable measurement gear, such as a measurement microphone and impedance measurement device. The course also recommends free acoustical measurement software, REW, supplemented with an Excel spreadsheet to address its limitations.
Overall, this course provides a comprehensive, beginner-friendly pathway into loudspeaker measurement techniques, empowering you to optimize your audio systems and even venture into DIY speaker design. Whether you’re a hobbyist or a professional, I highly recommend this course for its practical approach and clear instructions.
