Abstract
Hearing aid equivalent input noise (EIN) measures assume the primary source of internal noise to be located prior to amplification and to be constant regardless of input level. EIN will underestimate internal noise in the case that noise is generated following amplification. The present study investigated the internal noise levels of six hearing aids (HAs). Concurrent with HA processing of a speech-like stimulus with both adaptive features (acoustic feedback cancellation, digital noise reduction, microphone directionality) enabled and disabled, internal noise was quantified for various stimulus levels as the variance across repeated trials. Changes in noise level as a function of stimulus level demonstrated that (1) generation of internal noise is not isolated to the microphone, (2) noise may be dependent on input level, and (3) certain adaptive features may contribute to internal noise. Quantifying internal noise as the variance of the output measures allows for noise to be measured under real-world processing conditions, accounts for all sources of noise, and is predictive of internal noise audibility.

The level of internal noise reduced to the input


Explanation:
Уровень внутренних шумов, приведённых кO входу
The level of internal noise [singular] reduced to the input
приведение к общему знаменателю — reduction to a common denominator
E.g.: The signal contrasts required to achieve threshold were reduced by a factor or two or more after training at all levels of external noise. .... The perceptual template or filter describes the observer's overall filtering characteristics in a particular task and reflects a weighted combination of inputs from basic visual mechanisms. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC25004/
