Fun Facts
- 🌊 20 Hz is often considered the lower limit of human hearing (if you can hear it at all)
- 💨 40 Hz produces a warm, deep bass feeling
- 🎵 60 Hz is the fundamental frequency of AC power in North America
- 🎼 80–120 Hz range is where you get that concert-level bass thump
Safety & Best Practices
Start Low
Always begin at lower volume. Low frequencies can surprise you if volume is too high.
Take Breaks
Limit sessions to 10–15 minutes. Extended exposure to low frequencies can cause fatigue.
Protect Hearing
Keep volume reasonable. Sustained high volume at any frequency can damage hearing.
Use Quality Gear
Better equipment provides safer, more accurate bass reproduction and less distortion.
