Features:
1. Advanced screening options, using TEOAE (transient evoked otoacoustic emission) and DPOAE (distortion product evoked otoacoustic emission) technology, can effectively screen newborn hearing.
2. Mass storage, wireless bluetooth printing technology, flexible printing.
3. The equipment has a noise-rejection design and can be normally used in the normal environment without the silent room.
4. Ultra-light probe design can effectively suppress noise interference. Detachable transparent probe sound catheter can clearly see whether there is dirt, easy to clean and maintain.
5. Easy to carry and use
