1 Introduction

1 Introduction

1.1 Intended use

AURICALHIT is intended for testing purposes by audiologists, hearing instrument dispensers, and other health care pro­fessionals in testing programmable hearing instruments.

AURICALHIT is designed for Hearing Instrument Testing and Coupler-Based Fitting.

AURICALHIT connects via USB to a computer running the OTOsuite software.

• With the OTOsuite HITModule you can perform traditional hearing instru­ment testing according to either the ANSI or IEC test protocols, and obtain a
consistent picture of every hearing instrument, regardless of manufacturer or
type.

• With the OTOsuite PMM Module you can perform Probe Microphone Meas­urements in a coupler for pre-programming and pre-fitting hearing instruments
without the client being present.

Required qualifications

It is assumed that the user has a basic knowledge of how to compare the results of the hearing instrument tests with the
specifications from the hearing instrument manufacturer and to detect typical malfunctions of the hearing instrument.

4 The test chamber

Coupler adapter

The Accessory Box provides a range of adapters for easy positioning of different types of hearing instruments.

Coupler cavity

During tests in the test chamber, the hearing instrument is connected to a 2cc coupler cavity manufactured in accordance
with the ANSI standard. Alternatively, you can use an ear simulator.

Note•The ear simulator is not ANSI or IEC compliant, and is not recommended for RECD measurements.

You can use the Coupler Type icons in the toolbar to toggle between 2cc coupler and ear sim-
ulator. The selected coupler type is saved with measurements for later reference.

Coupler microphone

The coupler microphone is located in a coupler bottom piece which must be attached to the coupler cavity.

You can use the coupler microphone either directly in AURICALHIT or in the Accessory Box.
