peak clipping

the elimination of high-amplitude portions of speech waves by electronic means, causing some loss of quality but little, if any, loss of intelligibility. Peak clipping makes it possible to reduce high-intensity noise and enable a hearing aid or public address system to make the best use of its available power.

node of Ranvier

any of successive regularly spaced gaps in the myelin sheath surrounding an axon. The gaps permit the exchange of ions across the plasma membrane at those points, allowing the nerve impulse to leap from one node to the next in so-called saltatory conduction along the axon. [Louis A. Ranvier (1835–1922), French pathologist]
