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 REM Speech for
you to explore. |

NOAH™ & TIMS®
Compatible
The AVANT REM Speech 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. |

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. |

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 discrete
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. |
