+ CALCULATION ENGINE

HL-to-SPL Calculator

Input client thresholds and select age-appropriate RECD offsets. The engine computes eardrum SPL targets across standard audiometric frequencies using ANSI-compliant transforms.

Transducer & Age Inputs

Computed SPL Targets

Select HL transducer type (Insert + Foam Tip or Circumaural) and patient age to apply standard predicted RECD values.

Real-time conversion results at the tympanic membrane. Verify these values against your real-ear measurement system.

0.5 kHz: 42 dB SPL | 1.0 kHz: 48 dB SPL 2.0 kHz: 55 dB SPL | 4.0 kHz: 58 dB SPL

Predicted RECD Values

Reference matrix for age-appropriate predicted Real-Ear-to-Coupler Difference values. Derived from ANSI S3.46 standards for pediatric and adult populations.

Infant (0-6m)

Toddler (12-24m)

Adult (Standard)

High-frequency offsets up to +12 dB. Critical for avoiding over-amplification in small ear canals.

Moderate offsets averaging +6 dB. Standard predicted values used when cooperative probe-tube measures fail.

Baseline offsets tracking close to 0 dB. Used as default verification values for standard acoustic couplers.
