About this technology

Overview

The Improved Human Ear AuRal Detection Implementation Tool (IHEARDIT) determines the ability for the average human to detect a tonally dominated signal in a given background noise. The software compares the input signal at a human receiver location, and background noise level at that location. It then models the auditory response, including filtering, internal noise, and signal detection theory to predict human audibility.
