Operation Manual 

 

Auto Threshold:  

In addition to traditional manual testing, the AS608e incorporates a 

Hughson Westlake patient controlled automatic threshold test 
complying with ISO 8253. When the test is completed the results are 
easily recalled from the internal memory of the AS608e and 

transferred to the Diagnostic Suite PC software and stored in 
OtoAccess

TM

 or Noah. 

Hughson Westlake is an automatic pure tone test procedure. 
Threshold is defined as 2 out of 3 (or 3 out of 5) correct responses 
at a certain level in a 5 dB increase and 10 dB decrease test 
procedure. The Hughson Westlake is used to obtain pure tone 
thresholds automatically. 

 

Talk Forward

 

The Talk Forward function makes the AS608e easy to work with 

particularly in sound booth installations.
