Auto Threshold
The AD229b incorporates a facility for performing threshold determination automatically. The test procedure is based on the Hughson-Westlake method (up 5dB, down 10dB) and conforms to ISO 8253-1. Desired test frequencies may be selected freely by the user. After testing the test results can be recalled from the memory of the AD229b or transferred to a PC for database storage or printing

ABLB / Stenger
As well as the pre-programmed ABLB test the AD229b can perform the Stenger Test with pure tones for evaluating malingering, or as a binaural speech test with a monophonic speech signal.

PC connectivity provides options for data storage and full page reports via NOAH or the Interacoustics database software OtoAccess™.

Data Storage with Windows® Based Software
Transferring data to a PC is possible by two different applications. The Interacoustics database OtoAccess™ enables data collection from multiple instrument sources into one patient file.  Hearing aid information may 
also be included.
