The Verifit 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 acoustically-treated test chamber which houses a battery substitute (1.3 volt supply), 2 loudspeakers, a
reference microphone for controlling the signal from the loudspeakers, 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 and a custom keypad.
b) an analyzer/display unit housing a flat-panel video display, power supply, signal generation, measurement and
control electronics and two sound-field loudspeakers.
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.
The analyzer attaches to the acoustic test chamber via two 15-conductor cables. The acoustic test chamber
provides connectors for the microphones used for controlling the stimulus and measuring the response. For HIT
mode, a reference microphone, coupler microphone and a battery simulator are normally connected via
connectors provided inside the acoustic test chamber. For REM mode, two probe modules – each containing a
reference microphone and a measurement microphone, and a real-ear to coupler difference (RECD) earphone are
normally connected via connectors situated on the front of the acoustic test chamber. A connector and volume
control for headphones, used to monitor coupler and probe microphone signals, are provided on the front right
side of the test chamber.
There are connectors on the rear of the main display unit for 4 USB devices (flash drives, a QWERTY keyboard,
mouse, printer, barcode scanner), external speakers, an external HDMI monitor and connection to a network
(LAN) (serial number 4671 and higher). Units with serial number below 4671 have connectors for 2 USB
devices, an external VGA monitor, parallel printer, external speakers, a local area network (LAN) and an RS223
serial port (not supported in this version of software).
Electrical supply input requirement: 100 – 240 Vac 47 – 63 Hz 250VA
A hospital grade grounded outlet is required.
