Sonic Tension Meter Calculation
Sonic tension meter calculation is a critical process in determining the tension of a wire or cable. It’s importance lies in ensuring the safety and longevity of structures that rely on these elements, such as suspension bridges, guyed towers, and cable-stayed bridges.
How to Use This Calculator
- Enter the frequency of the wire in Hertz (Hz).
- Enter the velocity of sound in meters per second (m/s).
- Enter the diameter of the wire in millimeters (mm).
- Click ‘Calculate’.
Formula & Methodology
The formula used in this calculator is derived from the wave equation for a string: T = ρ * (2 * L * f)^2, where T is the tension, ρ is the linear density, L is the length, and f is the frequency. In this case, the linear density is calculated as ρ = π * (d^2) * ρ_m, where d is the diameter and ρ_m is the material density.

Interactive FAQ
What is the unit of tension?
The unit of tension is the newton (N).
How does temperature affect the calculation?
Temperature affects the velocity of sound, which in turn affects the tension calculation. The formula used in this calculator assumes a temperature of 20°C.
