RESONANCE r15c audiometer - Windows PC connection

A compact and versatile instrument designed for a comprehensive auditory evaluation, with precise functionality and data management via wireless connection. Ideal for quick and reliable diagnoses in any clinical setting.

Advanced portable audiometer, designed to offer audiometry, tympanometry, acoustic reflex and masking, with both air and bone conduction tests.
Thanks to integrated connectivity, this device allows for simple and seamless data management, storage, and sharing.
Equipped with a motherboard that ensures excellent performance in terms of power, speed, and storage capacity, allowing up to 500 patient records to be stored; connectivity is guaranteed via Bluetooth and Wi-Fi.
It can integrate the OAE module for otoacoustic emissions, RE-Play (RESONANCE Interactive Play Audiometry), the RE-VO2 video otoscope, and the portable Wi-Fi thermal printer.

Available tests
Impedance audiometry: Middle ear analysis at 226 Hz and 1 kHz, with pediatric mode included.
Reflexes: Measurement of ipsilateral and contralateral reflexes.
Quick test: Impedance audiometry and reflex test sequence, with editable protocols.
Jerger norms and Auto Classification: Advanced tools for result analysis.
Pure tone audiometry: Storage of thresholds and UCL (Uncomfortable Loudness Levels) indications.
Speech audiometry.
Automatic audiometry: Based on the Hughson-Westlake algorithm for automatic threshold search.

Intuitive and multilingual interface
An icon-based system, designed to guide the operator simply and effectively through all phases, from performing tests to managing records.
The MDS software, included with every device, is distinguished by its reliability and ease of use.
