  • (20) The spin-spin relaxation time T2 may be estimated using multiecho pulse sequences, but the accuracy of the estimate is dependent on the fidelity of the spin-echo amplitudes, which may be severely compromised by rf pulse and static field imperfections.

Reverberate


Definition:

  • (a.) Reverberant.
  • (a.) Driven back, as sound; reflected.
  • (v. t.) To return or send back; to repel or drive back; to echo, as sound; to reflect, as light, as light or heat.
  • (v. t.) To send or force back; to repel from side to side; as, flame is reverberated in a furnace.
  • (v. t.) Hence, to fuse by reverberated heat.
  • (v. i.) To resound; to echo.
  • (v. i.) To be driven back; to be reflected or repelled, as rays of light; to be echoed, as sound.

Example Sentences:

  • (1) The reverberation times were 2.1 and 1.6 s. In quiet conditions at normal speech level (60 dBA), the perception was better without earmuffs than with them.
  • (2) In addition, several cells showed unusual firing patterns, such as delayed responses and reverberating afterdischarges.
  • (3) The proposed physical process by which the metaorganization principle is implemented is based on oscillatory reverberation.
  • (4) The fact, that following the cooling or ablation of the auditory cortex the rhythmic afterdischarge to sound clicks as well as spontaneous spindle bursts keep arising in the medial geniculate body without changing their patterns, militates also against the possibility of thalamocortical reverberation.
  • (5) In situations with reverberation and less background noise the difference is less marked.
  • (6) For the reverberant condition, the sentences were played through a room with a reverberation time of 1.2 s. The CVC syllables were removed from the sentences and presented in pairs to ten subjects with audiometrically normal hearing, who judged the similarity of the syllable pairs separately for the nonreverberant and reverberant conditions.
  • (7) The fossil fuel resistance, like the fossil fuel industry, is protean and sprawling – and each win reverberates for decades to come, because that’s how long pipelines and coal mines are built to last.
  • (8) There are reverberating circuits between the fundus caudati and the medial groups of the nigra characterized by their small cells, between the putamen and the postero-lateral cell groups of the nigra, between the caudatum and the rostral cell groups of the nigra, presumably with the specialization that the lateral caudatum is in two-way connection with the rostro-lateral cell groups of the nigra as is the medial caudatum with the rostro-medial cell group.
