Noise level estimated for all 468 Standard AGF (blue) and 468 FineGrain AGF (red) via the standard deviation of the baseline at the end of an ECAP recording (1.3–1.6 ms after stimulus onset) after averaging. The median noise level is given above each group. Note that Standard AGF was measured with clinical software (MAESTRO 4.1.2) and FineGrain AGF with a research tool provided by MED-EL whose different averaging algorithm and respective low-pass characteristics are the main cause for the lower noise floor of FineGrain AGF at the same number of averages
