Noise Dose Calculator (OSHA & NIOSH)
Calculate daily noise exposure dose (%), TWA (Time Weighted Average), and permissible exposure limits. Supports OSHA (5dB exchange) and NIOSH (3dB) standards.
NRR Calculator — Noise Reduction Rating (OSHA)
Calculate effective hearing protection attenuation. Supports NRR to dBA conversion, OSHA derating, and dual protection logic.

Ultrasonic Flaw Depth Calculator (Angle Beam UT)
Calculate exact flaw depth and surface distance for angle beam ultrasonic testing. Automatically computes half-skips, full-skips, and multi-leg V-paths.
Ultrasonic Beam Spread Calculator (-6dB Divergence)
Calculate the half-angle beam divergence (-6dB) for ultrasonic transducers. Optimize probe selection by determining beam width and far-field coverage.
Ultrasonic Angle Beam Calculator (Snell’s Law Refraction)
Calculate ultrasonic beam refraction angle using Snell’s Law for UT and NDT. This calculator uses sound velocity (V) instead of optical refractive index (n).
Ultrasonic Near Field Calculator (UT N-Point)
Calculate the Near Field length (N) for ultrasonic transducers. Avoid inspection errors by determining the natural focus point of your probe.
