🧠 WHAT YOU’LL LEARN

What sound actually is (vibrations + waveforms)

Frequency (Hz) and how it affects tone (bass vs treble)

Amplitude and loudness perception

The human hearing range (20Hz–20kHz)

Why your ears get fatigued during sessions

How engineers use this knowledge in real sessions

🎬 WATCH THE LESSON

⚠️ IMPORTANT: Watch this full lesson before moving forward. This knowledge applies to every chapter after this.

🎯 WHY THIS MATTERS (REAL-WORLD APPLICATION)

If you don’t understand sound, you’ll:

🚨Overboost frequencies

🚨Create muddy mixes

🚨Damage your ears over time

🚨Make decisions that don’t translate across speakers

Professional engineers mix with intention, not guesswork.

🧪 QUICK PRACTICAL EXERCISE

Open your DAW (Pro Tools recommended):

1. Load any track

2. Add an EQ plugin

3. Sweep frequencies from:

20Hz → 200Hz (Low End)

200Hz → 2kHz (Mid Range)

2kHz → 20kHz (High End)

 Train your ears to hear the difference.

⚠️ COMMON BEGINNER MISTAKES

❌Mixing too loud (ear fatigue = bad decisions)

❌Ignoring low-end buildup

❌Not understanding frequency balance

❌Thinking louder = better
