This course will consist of excerpts from each.
Sound System Design – Day 1 and 2
The performance of a sound system is heavily influenced by the room in which it is placed, so much so that the room’s acoustics must influence the design process. Everyone knows this by intuition, but few designers understand how to allow the room to influence the system design.
This 2-day Sound System Design seminar begins with instruction on room acoustics. Pat Brown will demonstrate how to collect and interpret the Room Impulse Response (RIR), which is the acoustic signature of the room. He does this in a fast, accurate, practical manner that reduces site time while yielding high quality, useful data.
From there, he will help you understand how the loudspeaker interacts with the room to produce a direct-to-reverberation ratio at each listener position. Understanding loudspeakers and their specifications is vital for selecting the best type of loudspeaker for your design goals.
Pat helps you understand and use specifications like sensitivity, directivity, power handling, and amplifier power ratings. He’ll demonstrate how to use 3D computer modeling in a practical way to evaluate how all of the design variables interact. Humans design sound systems, but the computer can speed the process.
Highly intelligible sound systems, just like good room acoustics, don’t happen by accident. Both are achieved by a purposeful process guided by over a century of theoretical understanding.
Opt EQ “Equalization Demystified” – Day 3
System equalization need not be complicated. It just needs to be done in the right order, with the right tools, and with an understanding of the processes and objectives.
Do you find yourself asking these questions?
- It seems like the more I equalize, the worse it sounds. Why is that?
- How can I do 80% of the equalization process in 20% of the time?
- What microphone placements yield the best equalization results?
OptEQ is a comprehensive approach to sound system tuning that combines contemporary and legacy design and equalization practices into a logical, accurate, repeatable process. OptEQ is a set of tenets that can be applied using almost any mainstream dual-channel FFT measurement system. It s based on principles, not products. When you know the objective and the steps, you can get there with the available tools.
OptEQ is a layered approach to sound system optimization.
- Layer 1 is direct field optimization that produces a reference response for the loudspeaker that confirms that it is functioning as designed and to its fullest potential.
- Layer 2 addresses anomalies that result from placement of loudspeakers near room boundaries and other loudspeakers. Good choices here can make a system much more equalize-able.
- Layer 3 addresses room issues such as low frequency build-up and resonances, using a dual-domain (time/frequency) approach.
As an experienced audio practitioner, you will leave this event with improved proficiency on your existing measurement system. As someone new to system tuning, you will leave the event with a clear understanding of what tools and practices are needed to bring the sound system to its full potential. OptEQ is for everyone.
Pat teaches this seminar with passion. Why? In his early days, he made the common mistakes and it cost him a lot of money and time. Pat had to learn these principles the hard way. He will show you tips and techniques that will greatly shorten your learning curve.
Which option should I choose?
This special one time event combines 2 days of Sound System Design with 1 day of OptEQ, which normally are 3 days of instruction each. We strongly encourage you to attend all three days, as the OptEQ materials presented in day 3 will be built upon foundational principles established in the two previous days. It’s true that poorly designed systems can be impossible to equalize, and well-designed systems can be effectively equalized in a short amount of time. In other words, system equalization starts at the design stage.
If you are a system designer or consultant, you may wish to skip OptEQ and attend days 1 & 2 only. Or, if you are already comfortable with sound system design principles, but want to sharpen your optimisation skills, you may find OptEQ adds the missing pieces to your system tuning game.
Course Materials Includes:
- Course Manual – It’s not a manual of PowerPoint slides. It is reference-quality and filled with useful graphics. You’ll get a PDF version after the course.
- Audio Click-Rule – A Windows calculator program that demonstrates the interaction of the variables in these systems.
- Support files and utilities that you will find useful
- Certificate of Completion
Who Should Attend:
Anyone who selects and places loudspeakers in rooms and does system optimization and equalization.
