一、纯音听力检查初诊时需要进行纯音听力检查。如有必要,可同时进行阻抗听力检查。纯音听力检查是测定气导和骨导最基本的检查。依此可以分类为传导性耳聋、感觉性耳聋,以及混合性聋。气导域值上升,骨导域值正常者属于传导性聋。气导和骨导域值同时上升者属于感觉性聋。气导和骨导值同时上升,而两者不一致,出现差别者,称为混合性聋。通常测定125、250、500、1000、2000、4000、8000H_z7个频率的气导域值,和250、500、1000、2000、4000H_z5个频率的骨导域值。听
First, the pure tone hearing tests need to be pure tone audiometry examination. Impedance hearing tests can be performed at the same time if necessary. Pure tone hearing test is the most basic test for the determination of air conduction and bone conduction. According to this can be classified as conductive deafness, sensory deafness, and mixed deafness. The value of air conduction field rises, the value of normal bone conduction area belongs to conductive deafness. Air conduction and bone conduction domain values rise at the same time belong to sensory deafness. Air conduction and bone conduction value rise at the same time, and the two are inconsistent, there are differences, known as mixed deafness. Guidance values of 125, 250, 500, 1000, 2000, 4000 and 8000H_z7 frequencies are usually determined and values of the bone conduction domains at 250, 500, 1000, 2000 and 4000H_z5 frequencies. listen
