Transmission Loss Calculator

Compute transmission loss TL = 10·log₁₀(1/τ) from transmission coefficient.

Input Data

Input Transmission coeff τ.

Results

30dB
TL = 10·log₁₀(1/τ).

At a glance:Transmission Loss Calculator: enter parameters to compute results; complements related calculators.

Formula

TL = 10·log₁₀( 1 / τ ).

How to Use

  1. Enter transmission coefficient τ (0–1).
  2. It returns TL (dB).

Case Studies

τ=0.001 → TL=30 dB

TL = 10·log₁₀(1000) = 30 dB.

FAQ

τ vs insulation?

τ = transmitted/incident intensity; smaller τ → larger TL → better isolation.
