threshold of sound
解釋
聽閾-
In this article, double threshold, iteration is applied to improve segmentation algorithm based on signal energy, and short - time zero - crossing rate is proposed for the first time to determine the exact boundaries between different components of heart sound
本文通過使用雙門限、迭代等方法,改進了基於信號能量的分段演算法,並首次引入短時過零率以更準確地定位分段邊界。 -

In order to study the effect of weak noise on the sound signal extraction of mouse ( mus musculus km ) inferior collicular ( ic ) neurons from environment, we examined the change in frequency tuning of neuron induced by a weak noise relative to 5 db below minimum threshold ( remt - 5 db ) of tone. 12 healthy adult mice ( 20 - 25 g, b. wt. )
本實驗旨在探討弱噪聲對小鼠( musmusculuskm )中腦下丘( inferiorcolliculusic )神經元聲信號提取的影響及其神經機制,我們選用相當于純音閾下5db的白噪聲( whitenoise ) ,比較加入噪聲前後神經元頻率調諧曲線的變化和注射-氨基丁酸( - aminobutyricacid , gaba )能受體拮抗劑荷包牡丹堿( bicuculline , bic )后對該變化的影響。 -
