The Social Hearing Index as an Improved Estimation of Legal Hearing Disability

Technology #2010-137

This invention describes a novel calculation called the Speech Transmission Index based Social Hearing Index (STI-SHI or social hearing index for short). The social hearing index can be calculated using standard pure tone hearing threshold data and supra-threshold measures of speech intelligibility. The STI-SHI can be useful in refining the legal definition of hearing disability and will also be an important tool for measuring the outcomes of ear surgeries or other hearing remediation methods.
