Home Studio Acoustics: Complete Guide

🎯 Common Room Problems

1. Room Modes (Bass Buildup)

• Problem: Some bass notes louder than others (room resonance)
• Symptom: Mixes sound boomy at home, thin everywhere else
• Solution: Bass traps in corners

2. Flutter Echo

• Problem: Parallel walls create metallic "ringing"
• Test: Clap hands, hear repeated echoes
• Solution: Absorption panels on walls

3. First Reflections

• Problem: Sound bounces off walls before reaching ears (false stereo image)
• Solution: Panels at mirror points (side walls, ceiling)

📦 Types of Treatment

1. Bass Traps (Priority #1)

• Purpose: Absorb low frequencies (40-250Hz)
• Placement: Room corners (floor-to-ceiling)
• Size: Bigger = better (minimum 12" thick)
• Priority: Treat ALL 4 corners first

2. Absorption Panels

• Purpose: Absorb mid/high frequencies (250Hz-20kHz)
• Placement: First reflection points, behind monitors
• Size: 2'x4' panels, 2-4" thick

3. Diffusers

• Purpose: Scatter sound (keep room "live" without echo)
• Placement: Behind listening position (back wall)
• When to use: After absorption is complete (not beginner priority)

📐 Strategic Placement

Priority Order

1. Bass traps in corners (4 traps minimum)
2. Behind monitors (2 panels kill wall reflections)
3. First reflection points (side walls at mirror points)
4. Ceiling above listening position (1-2 panels)
5. Back wall (diffusion or absorption)

How to Find First Reflection Points

1. Sit at listening position
2. Have friend hold mirror on side wall
3. Move mirror until you see monitor speaker
4. Mark spot → place panel there
5. Repeat for other side + ceiling

🛠️ DIY vs Pre-Made

DIY Acoustic Panels

Materials

• Owens Corning 703 (rigid fiberglass, 2" thick)
• Wood frame (1x3" lumber)
• Acoustic fabric (breathable, NOT canvas)
• Spray adhesive

Cost

• DIY: $15-20 per panel (2'x4')
• Pre-made: $40-80 per panel
• Savings: 50-70%

Budget Hacks

• Rockwool Safe'n'Sound: $1/sq ft at Home Depot (cheaper than 703)
• Moving blankets: $30 for 6 (hang on walls, 40% as effective)
• Closet recording: Clothes = natural absorption

🏷️ Recommended Brands

Budget-Friendly

• Auralex: Entry-level panels ($30-50 each)
• Foamily: Amazon basics ($20-30 each, thinner)

Mid-Range

• GIK Acoustics: Custom sizes, bass traps ($60-150)
• Primacoustic: Pro quality ($50-100)

Premium

• Vicoustic: Designer panels ($100-200)
• Artnovion: High-end diffusers ($200-500)

❌ Common Mistakes

• ❌ Foam egg crates: Useless (only absorb highs, not bass)
• ❌ Covering entire room: Over-damping = "dead" sound
• ❌ Ignoring bass traps: Most important, often skipped
• ❌ Wrong fabric: Canvas blocks sound (use acoustic fabric)
• ❌ Panels too thin: 1" panels don't absorb enough (use 2-4")

📊 Before/After Testing

Tools

• Room EQ Wizard (FREE): Measure room response
• Pink noise test: Play pink noise, measure with REW
• Clap test: Before = flutter echo, After = dead thud

What to Measure

• RT60: Reverberation time (target 0.3-0.5s for mixing room)
• Frequency response: Flat ±6dB = good
• Room modes: Deep nulls/peaks = bass traps needed
