Well, I am going! :sm29: :sm29: :sm29:

I will then be certified to judge SQ at USACi. The next step is to flank install judges so that I can learn that portion of the sheet too.

Judge 4 shows before WF'09 and I will be fully certified as a USACi SQ judge.

I am stoked!

Here is what we will be studying, and, just so you guys know, my car will have it's system designed by Mark and some of the greatest minds in SQ right now. Plus the added bonus will be the partial installation that will occur. All for 395 bucks! WOOT!

The Many Parts of Music

Definitions and Terms
Instruments and Vocalists
Amplified and Un-Amplified Performances
Performance Venues: Studios, Clubs, Concert Halls, Etc.
The Emotional Involvement - What is it about the music that gets our blood pumping?


Our Audio Reference

The standard with which we compare audio system performance

What is an appropriate reference, and how do we get one?
Live Performances
Live vs. Recorded Music
The Recording and How It Affects What We Hear
The Listening Room and Environment
Near-field, Far-field, Car-field?
The Sound Reproduction System - Studio, Home Audio, Headphone Systems, Etc.
So what is the “perfect” reference system?
Listening Critically to Recordings


Using Our Ears 101

A simple setup to teach yourself how to recognize acoustical problems
Equalization, crossovers, Signal delay, etc.
Comparison of analyzer measurement techniques with adjustments made by ear


Tools, Tools, Tools…….

CDs and Software
Acoustical Analyzers: (RTA, TEF, etc) How they work, how to use them, how to interpret the data
Other useful tools – oscilloscope, Radio Shack amplifier, DVM, etc.
Books, Articles, the Internet, and other sources of “information”
Your Ears - Definitely the most important and effective tool in your arsenal!!!!!
Using the Tools Most Effectively
Analyzing the Data

The Human Hearing System

Why We Hear What We Hear
Anatomy and how each part of the hearing system contributes to the aural experience
Do We All Hear the Same Things?
Hearing loss and how it affects what we can hear
Frequency Threshold Shift (a.k.a Listening Fatigue)
How We Localize Sounds – Spatial Responses
Localization Demonstrations
What is Ambience, anyway???
Perception of Frequency Response
Loudness Effects
Psycho-Acoustics
Distortion – How much is too much?


The Vehicle’s Acoustical Environment

Defining the Problem Areas
Reflective surfaces, absorptive surfaces, cats and dogs living together….
Near Field vs. Far Field – What do we really have?
Pathlength, pathlength, pathlength
Relative locations of tweeters, mids, and other drivers
Comb filtering, and other acoustical issues
Reflections Good and Bad…


Acoustical Treatments

What’s the purpose?
Types of Acoustical Treatments
Basic Acoustical Treatment Philosophy
Controlling “Bad” Reflections

Recognizing and Finding Reflections
Diffusion

Mid-bass and Midrange enclosures


Component Selection

Signal Processors
Front Stage Speakers

The Important Factors
Tools Needed
The Steps on How to Do It


System Tuning Tips and Techniques

Crossovers
Equalizers
Signal Delay
Dynamic processors
Multi-channel specific tuning
Using psycho-acoustics to your advantage


Speaker/Enclosure Frequency Response Testing

Consistent and realistic measurement techniques
Interpreting the data
A realistic approach to addressing some response problems


The Listener/System Interface
Keep it simple
Make it easy to deal with
Ear/Hand coordination
Computers and analyzers are great, but trust your ears!

Joe I'm going to keep saying this till you make it happen.

PLEASE talk mark into doing another class next may (around the middle). I'm going to PM him on another forum that were both on, and work it from that side.

I'm at the point with my abilities that a class like that would be a huge learning opportunity.

Still drives me NUTS I can't make this one.

it would be a learning oppurtunity. Mark is the man when it comes to that stuff. I read a couple articles not to long ago that he did on SQ. I learned alot just from the articles I read.

Stay tuned for a Youtube video of myself, Andy Jones, and Rick Sellers getting in and out of Mark's NASCAR soundoff machine. I laughed my butt off while watching it.
