Abstract
The present invention relates to a pure tone audiometer, and more particularly, to a pure tone audiometer with automated masking which is capable of automatically performing air-conduction and bone-conduction hearing tests and automatically performing a masking test, if necessary, so that a person obtains an accurate pure tone hearing threshold without others' assistance. The pure tone audiometer of the present invention can accurately perform the pure tone hearing test with automated masking without assistance from a doctor or an audiologist. Thus, with the pure tone audiometer, people can easily check their hearing ability for prevention and early detection of hearing loss and take swift action to cure hearing loss.
