ARC aud/REM combined


Audiometry/REM Combination

ARC UndersideThe AVANT ARC combines the power of PC-based Audiometry with the fitting and counseling benefits of REM & Live Speech Mapping into one compact device.

• Complete Air, Bone, Speech and Masking Audiometry
• Binaural Live Speech Mapping and REM
• Powerful 3rd Party Counseling Tools
• Built-in Special Tests, Word Lists and Auto-Scoring
• PC-based and Portable
• Small Footprint - approx. 8” x 5” x 1.25”




Available Tests
The ARC offers pure tone audiometry via earphones and bone conduction, masking and speech audiometry with SRT (Speech Recognition Threshold), WR (Word Recognition), SISI (Short Increment Sensitivity Index), ABLB (Alternate Binaural Loudness Balance) and Tone Decay Tests. Additional features are HLS (Hearing Loss Simulator), MHA (Master Hearing Aid), QuickSIN™ testing and automated audiometry. In addition to Live Speech Mapping, the AVANT REM software supports all traditional Real Ear Measurements and includes targets for MSS (Modified Speech Spectrum), DSL v5.0, NAL-NL1 and NAL-NL2 as well as HLS (Hearing Loss Simulator) and MHA (Master Hearing Aid) Modules.

Counseling Tools (HLS/MHA)
The Hearing Loss Simulator demonstrates the effect of the client’s hearing loss for the spouse or family member. The program attenuates an input signal to simulate the severity of the loss for the third party. The Master Hearing Aid Simulator demonstrates the benefits of amplification of a hearing aid to an inexperienced user. Using these tools can empower the patient and third party to make informed decisions about their hearing healthcare.
