Researchers at Arizona State University have developed an audiometric system that takes less time and automates most of the test activities thereby increasing accuracy and reducing operating cost.
The new system is a computer based system, which can quickly acquire a person?s hearing threshold. The system allows for a relatively accurate determination of the hearing sensitivity with less effort from the subject. The responses are correlated with exact sound pressure level measured in the real ear with systematic calibration. Thresholds are determined with a signal detection theory analysis that can assess the validity and accuracy of the measurement. Due to the fast threshold estimate, hearing sensitivity can be measured in higher frequency resolution than currently available techniques. The system promises accurate diagnosis of lesions in the inner ear and auditory system and more appropriate prescribing of hearing aid instruments with high precision.
