1.1 About AC440 Module

AC440 is the PC-based audiometry module for the Affinity 2.0

and Equinox 2.0

hardware platforms.

The AC440 software is an independent two-channel audiometer. It features tone audiometry for air and bone, speech testing and a variety of masking and signal types. Stimuli are presented using the PC keyboard, mouse or a dedicated audiometry keyboard. Test results are displayed on screen and saved to the associated database (e.g. Noah, OtoAccess™). They are immediately available for inspection, hearing aid fitting, printout, export, and so on. The AC440 module can also be operated external to a database in standalone mode.

The module is flexible, enabling the individual clinician to tailor the system according to their specific preferences. It permits the creation of an unlimited number of personalized test protocol settings and functions for different purposes and/or for different clinicians working at the same location. The system also provides you with the option to make individual print layouts, keep reports electronically, and compare actual curves to previous sessions. These numerous setup options can be very helpful and time saving in the daily clinical work environment.

In addition to the setup functions, the AC440 also contains counselling tools in order to help both patient and relatives to get a better understanding of the consequences of hearing impairment and why hearing amplification may be needed.

The AC440 contains the following tests:

 Air Conduction Audiometry o High Frequency Audiometry o Multi Frequency audiometry

 Bone Conduction Audiometry

 Free Field Audiometry

 Speech Audiometry

 Masking Level Difference (MLD)

 Master Hearing Aid (MHA) (counselling tool)

 Hearing Loss Simulation (HLS) (counselling tool)

 Short Increment Sensitivity Index (SISI)

 Weber

 Knaster

 Stenger

 Tone Decay Test

 TEN test

 QuickSIN

Frequently asked questions

The AC440 is a PC-based audiometry module for the Affinity 2.0 and Equinox 2.0 hardware platforms, functioning as an independent two-channel audiometer for tone and speech testing.

To launch AC440 from Noah 4, first ensure the Affinity hardware is on and connected. Then, open Noah 4, search for and select the patient, and click on the Affinity Suite module icon at the top of the screen.

The AC440 includes Air Conduction Audiometry (High Frequency and Multi Frequency), Bone Conduction Audiometry, Free Field Audiometry, and Speech Audiometry.

The AC440 module contains counselling tools such as the Master Hearing Aid (MHA) and Hearing Loss Simulation (HLS) to help patients and relatives understand hearing impairment and the need for amplification.

The "Extended Range +20 dB" feature extends the testing range and can be activated when the testing dial setting gets within 55 dB of the transducer's maximum level, allowing for higher intensity tests.

Yes, the AC440 module allows for the creation of an unlimited number of personalized test protocol settings and functions, enabling clinicians to tailor the system to their specific preferences.

What is Masking Help in audiometry?

Masking Help indicates whether masking is required during audiometry and if undermasking or overmasking is occurring. It is intended to aid inexperienced clinicians.
