ASSR

Specifications:

• Probe Performance Check: Assess sound pressure, speaker symmetry, and probe fit for accuracy.
• Calibration: Perform in-ear calibration with volume adjustment for precision.
• Noise Detection and Rejection: Identify narrow-band noise, use weighted averaging for noise calculation, and reject artifacts.
• Employ 1.22 f2/f1 ratio at 48 kHz with L1 – 70 dB criterion and 4096-sample interval. Utilize diverse stimulus modes for multi-channel DPOAE, auto frequency adjustment (1-8 kHz), and default SNR stop criteria for efficient testing.

Additional feature:

• Simultaneous measurement on left/right ear with 2 probes
• Entertainment mode for all OAE modules
• Optional Database Software for easy data management and result export
• Noah compatible, facilitating interoperability with EMR systems
