Signal averaging in real ear probe tube measurements.
https://www.ncbi.nlm.nih.gov/pubmed/2262081
The minimum time-domain signal averaging required to reduce the degrading effects of background noise to levels acceptable for the production of valid real ear unaided responses (REURs) was established for three normal listeners at various signal-to-noise (S/N) ratios. Generally, averaging was not required at S/Ns of 20 dB or higher.

https://en.wikipedia.org/wiki/Signal_averaging
Signal averaging is a signal processing technique applied in the time domain, intended to increase the strength of a signal relative to noise that is obscuring it. By averaging a set of replicate measurements, the signal-to-noise ratio (SNR) will be increased, ideally in proportion to the square root of the number of measurements.

The most commonly employed technique is signal averaging, whereby a number of EEG segments, each time-locked to the same class of event, are averaged to give a waveform in which consistent features of the segments (the ERP) are retained while features that vary across segments are attenuated (see Fig. 1). Depending on the relative sizes of the ERP and the …

pathway. Summation or averaging of the response is necessary due to the size of the auditory response in relation to the body’s ongoing neurophysiological activity. A typical human adult EEG (electro-encephalogram) signal is about 10µV to 100 µV in amplitude when measured from the scalp, while auditory brainstem

International Journal of Audiology, 49, 891-903 [[3]]. The signal is based on natural recordings, but is largely non-intelligible because of segmentation and remixing. When used for hearing aid and probe-microphone measurements, the signal describes the gain at different percentiles of the speech level distribution. The signal reflects a female speaker incorporating …

The EEG represents all body electricity, with only a percent or less contributed by the auditory nerve and auditory brainstem. The signal averaging computer eliminates, or 'averages out', the 99% of the EEG that is not auditorily generated and produces an auditory-only record, the ABR. The procedure is efficient, reliable and inexpensive.
