pure tone audiometer with automated masking

The invention and the display unit 10 to display the information and pure-tone audiometry result of the procedure to use to the car easily lungs pure-tone audiometry possible without a doctor or a professional audiologist relates to a pure-tone audiometry equipment; It generates an electrical signal in response to a control signal to the sound output generating circuit 20; And a bone conduction headphone output unit composed of the vibration body (30) for receiving an electrical signal from the sound generating circuit 20 output to generate a pure tone or a noise for a pure-tone audiometry and; The pure tone generated from the output section 30, and are the input unit 40 provided so that the user can enter the reaction; Passing the control signal to generate a pure tone through the headphone output of the unit 30 and the airway hearing checking (50) to check the hearing of the pure tone that is passed through the ear canal and to regulate the pure tone according to the user response; Passing the control signal to generate a pure tone with a bone conduction oscillator of the output section 30 and the bone conduction inspection unit 60 to check the hearing loss for pure tones delivered by controlling the pure tone, depending on the user response via the skull; The airway is the opposite sides of the ear hearing difference measured by the hearing inspection or more than 35 dB or results measured by the bone conduction inspection section either side ear relative to the the side of the ear low and high side of the ear hearing threshold and relatively hearing loss hearing threshold of If the difference between the bone conduction hearing thresholds than 15 db shielding while checking to hear the sound shielding the ear side relative to the low hearing threshold test hearing by passing the control signal to deliver a pure tone and the other ear; The airway hearing checker 50, according to a control signal delivered from the bone conduction inspection section 60 and the shielded inspection section 70 passes the control signal to generate a sound in the sound generating circuit 20 and the input unit 40 wherein the user's response is passed through airway hearing checker 50, the bone conduction inspection section 60 and the shield is transmitted to the check unit 70, the airway hearing checker 50 and the bone conduction inspection section 60 and the shielded inspection ( relates to a hearing test device characterized in that comprises a; with the progress of 70), the control unit 80, which passes a control signal to the display unit 10 to display the information and test results of the use process. Accordingly, because without the help of a professional audiologist or physician alone quickly and accurately place the pure-tone audiometry available cars lungs has the advantage of possible prevention and early detection of hearing loss. Pure tone audiometry hearing prayers bone conduction headphones, bone conduction hearing test vibrating car lung
