This tool requires access to your device's motion sensors.

Place your phone on a vibrating surface to measure its frequency.

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

  1. Tap "Start Measurement" and grant motion sensor access
  2. Place your phone flat on the vibrating surface
  3. Wait 2-3 seconds for the frequency to stabilize
  4. 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.

  • Results are estimates and may vary based on actual conditions.
