Clinical reference matrices
Quick-reference lookup for transducer corrections, calibration norms, and acoustic reflex interpretation. Built exclusively for rapid verification on the clinic floor.
Transducer standards
ANSI S3.6 reference levels and transducer correction offsets compiled into high-contrast clinical matrices for rapid verification during equipment calibration.
Transducer Offsets
Acoustic Reflex Norms
Reference equivalent threshold sound pressure levels (RETSPL) for standard earphones and bone vibrators, compiled for rapid clinic verification.
Interpretation matrix for ipsilateral and contralateral acoustic reflex thresholds and decay parameters, optimized for point-of-care diagnostics and patient evaluations.
TDH-39: 0 dB HL = 45.0 dB SPL at 1 kHz ER-3A: 0 dB HL = 26.5 dB SPL at 1 kHz B71: Force levels compliant with ANSI standards.
Normal: 70-100 dB HL thresholds Decay: Positive if amplitude decreases by 50% or more within 10 seconds at 500 Hz or 1 kHz.
