Examples

Abstract: Speech recognition scores in noise are improved for some subjects who wear hearing aids that reduce low-frequency noise with an adjustable high-pass filter circuit.
Academic text (1993) -
In this type of processing, the cutoff frequency of a high-pass filter moves lower in frequency as the amount of low-frequency energy decreases.
Academic text (1990) -
The detection circuit that controls the high-pass filter tends to be most sensitive to energy around 250-300 Hz.
Academic text (1990) -
For some hearing-impaired subjects, high-pass filtering resulted in improved speech recognition that was related in a somewhat predictable sense to reduced upward spread of masking.
Academic text (1993) -
Further, monosyllabic speech recognition in noise testing indicated improvements in the performance of the hearing-impaired subjects related to the decrease of upward spread of masking in the high-pass filtering conditions.
Academic text (1993) -
A high-pass filter allows higher frequency sounds to be heard more clearly by reducing lower frequencies.
-
Using a high-pass filter in the audio system helps eliminate background noise from lower frequency sources.
-
The technician adjusted the high-pass filter to ensure only the desired frequencies passed through in the recording.
Antonyms

Morphology
high-pass + filter
The meaning 'a filter that allows high frequencies to pass while attenuating lower ones' is directly compositional from 'high' + 'pass' + 'filter' — a device that lets high (frequency) signals pass. This follows a common technical naming pattern (cf. 'low-pass filter') and has clear cross-linguistic equivalents, so a B1 learner who knows the constituents can reasonably infer the meaning.
Etymology
The noun high-pass filter comes from the simple image of a gate that lets high sounds pass while the filter stops low sounds. So, it is a device that 'lets higher sounds through' and 'keeps out lower ones'.
