Head-and-torso simulators

Definition

Head-and-torso simulators are sophisticated devices designed to mimic the acoustic characteristics of human listening. These simulators capture sound as a human would experience it, utilizing microphones positioned within a model of a human head and torso to replicate the way sound waves interact with the body, including effects like diffraction and reflection. This technology is essential in understanding how sound behaves in various environments and is particularly useful in auralization, where it helps create realistic sound simulations for testing acoustics in different spaces.
