Frequency Spectrum
Common Vibration Frequencies
| Source | Typical Frequency | Notes |
|---|---|---|
| Washing machine spin | 10-25 Hz | Varies with load balance |
| Car engine idle | 15-35 Hz | RPM dependent |
| Refrigerator compressor | 50-60 Hz | Matches AC frequency |
| Electric motor hum | 50 or 60 Hz | AC line frequency |
| HVAC system | 8-25 Hz | Fan and compressor |
| Building sway | 0.1-1 Hz | Wind or seismic |
| Phone vibration motor | 130-200 Hz | Haptic feedback |
About Vibration Analysis
This tool uses your device's built-in accelerometer to detect and measure vibrations. The dominant frequency indicates the primary oscillation rate of the vibrating object.
How to Use
- Tap "Start Measurement" and grant motion sensor access
- Place your phone flat on the vibrating surface
- Wait 2-3 seconds for the frequency to stabilize
- Read the dominant frequency and amplitude
Understanding the Results
- Dominant Frequency (Hz): How many times per second the object vibrates
- Amplitude (g): Peak acceleration strength (1g = Earth's gravity)
- RMS Level: Average vibration intensity over time
Tips for Accurate Measurements
- Ensure your phone is firmly placed on the surface (use a case or tape if needed)
- Z-axis measures vertical vibrations (best for flat surfaces)
- X/Y axes measure horizontal vibrations
- "Magnitude" combines all axes for general vibration level
- Lower frequencies (<5 Hz) require longer measurement times
Limitations
Phone accelerometers typically have a sample rate of 60-100 Hz, which means frequencies above ~25-50 Hz may not be accurately detected (Nyquist limit). For high-frequency vibration analysis, professional equipment is recommended.
