Abstract：A auditory perception plays an important role in hearing assessments. A model was developed to transform amplitudes to sound pressure using acoustic parameters based on the auditory characteristics for automatic generation of standard pure tone test signals. The sounds were adjusted based on human auditory perception for a reliable algorithm to compute the hearing threshold based on multiple judgments. A correction algorithm for the hearing threshold is given for noise masking. A pure tone test was developed for an embedded platform to compare the hearing curves of normal people with standard hearing ranges. The results show that the system can quickly and easily check hearing changes, is reliable, and can be used for hearing screening.
