Dual Channel Audiometry

The Audiometer is easy to operate. Perform air conduction, bone conduction, masking and speech testing using the mouse and/or keyboard with ease. All measurements, including discreet frequency MCLs and UCLs are automatically plotted to a single Audiogram using standard symbols. A unique dynamic display of the test word in speech testing simultaneously counsels third parties while testing SRT and speech understanding.

Live Speech Mapping

Live Speech Mapping has become the popular and successful approach to fitting today’s high tech hearing instruments. LSM utilizes actual speech as the input for measuring the Aided Response in real ear measure-ments. Speech provides an interesting and familiar stimulus for the patient and provides the hearing instrument with the signal it is required to process. The key to a successful fitting using LSM is the ability to use the patient’s own dynamic range as the target; insuring that soft speech is audible, conversational speech is comfortable and loud speech and sounds are tolerable.

Real Ear Measurements

REM functions are provided for: REUR, REUG, REIG, REAG, REAR, REOR, REOG and RECD. The fitting rules for REIG include: NAL(RP), Fig 6, 1/2gain, POGO I and II,1/3 gain and Berger. All REIG targets can be manually edited for conductive corrections or personal preference.

Occlusion Effect

An objective measurement of occlusion effect enables you to determine the cause of the patient’s voice sounding “hollow” or “like speaking in a barrel.” Using the patient’s own voice for the occlusion effect measurement is the key to success of this test.

3-D Speech Mapping

3-D Speech mapping offers a new look at the speech map overtime and analyzes its dynamics. 3-D Speech is a true three-dimensional model, utilizing perspective, scaling, rotations and highlights. This module is currently in experimental use and is provided with the AVANT for you to explore.

NOAH™ & TIMS® Compatible

The AVANT performs from within NOAH™ & TIMS® software thereby allowing all data to be saved to the NOAH™ & TIMS® database. Live Speech Mapping also performs in the “on top” mode to allow for simultaneous programming and verification of the hearing instrument. The Hi-Pro programming hardware is built into the AVANT.

Hearing Instrument Testing

Compare the 2cc coupler response of the hearing instrument to the manufacturer specification to ensure quality performance or to detect possible malfunctions of the hearing instrument. The Hearing Instrument Test program is used to measure the hearing instrument’s response in a 2cc coupler in the test box. The ANSI standard tests are available in an automatic sequence or for select measurements.

Hearing Loss Simulation

The Hearing Loss Simulator “simulates” the effect of the patient’s hearing loss for the spouse or family member. The program attenuates an input signal to simulate the audiogram. The program will record the 3rd parties voice and play it back “simulated”. It is a powerful experience for the spouse or family members to listen to how their voices are distorted by the hearing loss.
