The Formula Explained

STL is calculated using the formula: STL = 20 * log10(frequency * materialDensity * materialThickness)

Glossary of Variables

  • Frequency (Hz): The sound frequency in hertz.
  • Material Density (kg/m³): The density of the material in kilograms per cubic meter.
  • Material Thickness (m): The thickness of the material in meters.

How It Works: A Step-by-Step Example

For a frequency of 500 Hz, material density of 2400 kg/m³, and thickness of 0.1 m, the STL is calculated as follows: STL = 20 * log10(500 * 2400 * 0.1) = 48 dB.

Frequently Asked Questions (FAQ)

What is Sound Transmission Loss?

Sound Transmission Loss (STL) is a measure of the reduction in sound energy as it passes through a material, often used in acoustics and noise control engineering.

Why is STL important?

STL is crucial for designing buildings and products that require soundproofing or noise reduction to improve comfort and privacy.
