Introduction to the course and its contents.
You will learn what a sound wave is and how it is created.
You will learn what's frequency.
You will learn the physical concept of octaves.
You will understand what the wavelength is and its importance.
You will know the basic components of sound.
You will understand the sound pressure level.
You will know how to measure sound and SPL.
You will understand the inverse-square law related to sound.
You will understand the two main acoustic problems.
You will understand the common approaches to analyze the sound.
You will understand how early reflections and echos are created.
You will understand the phenomenon of reverberation.
You will understand sound absorption.
You will know the challenges to absorb low frequencies.
You will understand how to absorb low frequencies.
Apply absorption principles to control reverb time using RT60 and early decay time. Reference RT60 ranges for choral music, concert hall, chamber music, recording studio, home studio, and mastering spaces.
Calculate RT60 by multiplying absorption coefficients by surface areas to obtain Sabines, then sum them and apply RT60 = 0.161 V / A for 500 Hz and other frequencies.
You will learn how to calculate the amount of absorbent material for a room.
Explore standing waves and resonant modes in rooms, focusing on low frequencies, nodes and antinodes, and three-dimensional pressure patterns that create zones of loud and near-silent sound.
Explore how room modes create standing waves, with fundamental and harmonic axial modes set by room length, producing center loudness variations and notes like G on bass guitar.
Compare irregular rooms to rectangular rooms, noting resonances occur in all shapes. Irregular rooms have less intense nodes and anti-nodes but are harder to predict; avoid cubic or related dimensions.
You will learn how to design a resonant bass trap.
You will know how diffusers work.
Place monitors five to sixty centimeters from the wall to reduce bass boosts from reflections; form an equilateral triangle with your ears, keep the tweeters at ear height.
You will know the ideal proportions for a home studio.
Apply these foundations of applied acoustics to your home studio and implement changes that improve sound. Explore more about audio topics like equalization, compression, and mastering, and check other courses.
Acoustics is the branch of physics that studies vibrations. Sound is part of acoustics, as it is generated by vibrations. One of the most common applications of acoustics is architectural acoustics, which deals with sound in rooms, studios, auditoriums and other venues; and that's the foundation of this course.
This is a beginners' course about acoustics, and here you will learn the basics of sound indoors and outdoors, its behavior and treatment. This knowledge will help you to improve the acoustics of your home studio, home theater, rehearsal room, recording and post-production studios, etc.
By applying the principles of acoustics, you will improve the listening experience through a sound system. You may have the best microphone or great speakers but, if the acoustics of your room is poor, the results won't be great either.
A common problem with poor acoustic treatment is that your mix may sound ok in your studio, but very different when you listen to it somewhere else. These kinds of problems are minimized when you treat your studio properly.
This course is aimed at musicians and creative people who need to work with sound:
Music producers
Musicians and singers
Sound technicians
Podcasters
Multimedia producers
Audiophiles
Although acoustics is often associated with advanced math, this course covers the basic principles in a practical and easy-to-learn way. A lot of knowledge has been condensed and properly organized, so you can learn fast. You can learn something new in just 15 minutes a day!*
"Very informative & engaging! Marco explains things in great detail, yet in a manner that is easy to follow and far from boring." James Blomquist.
"I wanted to learn about acoustic treatment. But the scattered information on the internet was just confusing. Then I found this course. It explains everything I want to learn clearly and briefly. Best regards to Marco Galvan." Tarik Mutlu.
You will be guided by a certified audio instructor (Meyer Sound, Yamaha, Steinberg), with more than 20 years of teaching experience at all levels. From professional seminars and courses up to university lectures, so, teaching quality is guaranteed.
