- •
An ear canal electrode can also be used to record low-frequency CMs masked by high-pass noise.
- •
Such noise reduces CM amplitudes as low-frequency CMs have to pass through basal cochlea.
- •
Such reduction is noise-intensity dependent.
- •
The reduction is not completely linear as a function of masking noise intensity.
- •
These findings may lead to new applications, e.g., optimization of masking intensities.
