Shewi's IEM potential list

targets/Shewi Target (DFHRTF).txt

Rig: B&K 5128 Industry standard measurement rig. Complies with ITU-T Rec. P.58 and has the most accurate acoustic input impedance, which is crutial in the measurement accuracy of high output impedance devices such as IEMs or true wireless earphones.  |  Norm: Variable Attemps to find the best normalization frequency for each earphone. Weights are ignored during calculation.  |  Decay Factor: 2700 Controls how quickly the potential decreases as the weighted error (Δ) increases. Potential = 10 × e−Δ / D A larger D makes the potential fall less aggressively.  |  Weights: Sub: 0.2 20Hz - 50Hz | 66 values • Bass: 0.5 50Hz - 100Hz | 46 values • Mids: 1 250Hz - 2kHz | 144 values • Canal: 2 2kHz - 4kHz | 46 values • Pinna: 3 4kHz - 15kHz | 92 values  |  Data limit: 16kHz Ignore data above that frequency in Potential calculation.

# Model Potential Should not be taken too seriously: you can easily add or substract 0.5 to the potential, because of positional variation, eartip used, or HpTF variation (not depending on anatomy but the IEM's load). W Error
