Resonance R15C Lite Screening Portable Combined Audio-Tymp

Bring full clinical capability wherever your patients are with the Resonance R15C-Lite Portable Audio-Tymp—the only handheld device that combines screening/clinical audiometry and advanced middle ear analysis in one ultra-light package.

Perform air-conduction pure-tone audiometry from 125–8000 Hz (-10 to 110 dB HL) with automatic Hughson-Westlake threshold testing and talk-forward function, plus complete tympanometry at 226 Hz and high-frequency 1000 Hz (perfect for neonates and infants), automatic ipsilateral acoustic reflex testing (0.5, 1, 2, 4 kHz), quick combined tymp+reflex protocols, and customisable test sequences—all managed through a bright, large colour touchscreen with intuitive icons and child-friendly animations.

Weighing just 570 g and powered by a long-life rechargeable battery, the R15C-Lite features an internal patient database for over 500 records and seamless wireless data transfer to PC via Resonance MDS software. Fully compliant with IEC 60601-1 and FDA cleared, it’s the go-to choice for schools, mobile clinics, pediatrics, and ENT practices that refuse to compromise on accuracy.
