CDL equations proposed by various studies along with Greenwood frequency function.
| Studies | CDL equations | 
|---|---|
| Escude et al4 | CDL(LW) = 2.62 × A × loge (1+ (Ө/235)) | 
| Erixon et al5 | CDL(LW) = 3.08 × A + 12.44 | 
| Alexiades et al8 | CDL(OC) = 4.16 × A − 4 | 
| Koch et al22 | CDL(OC) = 4.16 × A − 5.05 | 
| Greenwood et al10 | F = A (10ax − k) | 
Where A is a constant (165.4) and k = 0.88. x is the proportion of the basilar membrane length.
