Their more hyperpolarized Vm (about –65 mV), due to the much smaller resting MT current, and consequently greater membrane time constant, means that the responses of basal cells to even low level sounds summate into a DC membrane potential shift that is proportional to stimulus intensity.
Second, an activation was observed in the auditory cortex (Heschl's gyrus and planum temporale), likely to be related to low-level sound processing.
It's partially an aesthetic decision on Wheeler's part to include that low-level sound, and partly a safety decision.

As PAC lies between inferior colliculus and secondary auditory areas, it has been proposed to be a likely locus where representations of physical low-level sound properties may be transformed to behaviorally relevant representations (Nelken 2008).
The constant, low-level sound drowns out other noises that may prevent you from falling asleep.
You might also invest in a white noise generator device or application for your iPad, as they've been proven to help people fall asleep more quickly; moreover, the constant, low-level sound can also help mask more abrupt noises that may disturb you when you finally do fall asleep.[3].
This is just as well, because research shows that most people feel more comfortable in an environment with low-level sounds, commonly called ""white noise".
Their role is to amplify responses to low-level sounds and compress responses to high-level sounds.
OAEs originating in the cochlea are low-level sounds in response to a given stimulus and can be measured in the outer ear.
By analyzing the shared segmentation errors from all the submitted systems, we conclude that a large percentage of errors was induced either by the presence of a low level of sound in the background (23%) or by the overlapping speech (21%), while the annotator mistakes accounted for only 8% of the total amount of shared errors.
