How did Koubori et. al., explain the results of their auditory brainstem experiment (ABR) experiment?

Unremarkable

Explained by the normal equal-loudness-level contours

Answer :

Final answer:

Kobouri et al., in their ABR experiment, used the concept of equal-loudness-level contours (or 'Fletcher-Munson curves') to explain their findings. These curves show that different frequencies require different sound pressures to achieve the same perceived loudness, which can cause variability in ABR responses.

Explanation:

Kobouri et al., in their auditory brainstem response (ABR) experiment, explained their results using the concept of the equal-loudness-level contours. These contours, or 'Fletcher-Munson curves', illustrate a characteristic of human auditory perception - different frequencies require different sound pressure levels (SPLs) to achieve the same level of perceived loudness. In their experiment, this concept explains the potential variations in the auditory responses captured by ABR.

In a simplified context, let's say you're listening to two sounds, one a high-pitched noise and the other a low-pitched noise, at the same physical volume. You might perceive the high-pitched noise to be louder. This happens due to these 'equal loudness-level contours' - our ear is more sensitive to certain frequencies.
