Product description

The Axiom is a hearing aid analyzer intended to be used by hearing care professionals such as audiologists and

hearing aid specialists to verify the electro-acoustic performance of a hearing aid connected to a standard

earphone coupler or while worn on the ear of the end user. It consists of:

a) an integrated acoustically-treated test chamber which houses a loudspeaker, a reference microphone for

controlling the signal from the loudspeaker, and a standardized earphone coupler connected to a measuring

microphone for the purpose of measuring the sound level produced in the standard coupler by a hearing aid.

b) signal generation, measurement and control electronics.

c) two real-ear measurement microphone assemblies, each housing a reference microphone for controlling the

signal from the sound-field speakers and a probe microphone connected to a thin silicone tube which may be

inserted into the ear canal for the purpose of measuring the sound level in the ear canal produced by a hearing

aid.

d) a miniature earphone used to measure the real-ear to coupler difference (RECD) useful in estimating the

sound level produced in an individual ear from measurements in the standard earphone coupler.

There are 4 connectors for USB devices (flash drives, a QWERTY keyboard, mouse, printer, barcode scanner), a

LAN port, and connectors for the external power supply (supplied), external loudspeaker (supplied) and 2

connectors for external HDMI video monitors (not supplied).

Electrical supply input requirement: 100 – 240 Vac 47 – 63 Hz 1.35A

A hospital grade grounded outlet is required.
