隆巴德效应

隆巴德效应:在强大噪声环境下,说话人不得不提高声音的效果;包括提高声音的频率,强度,延长语句等,希望使对方能听到。这种现象称为隆巴德效应。这是法国耳鼻喉科医生爱蒂安·隆巴德于1909年发现的。

在大噪声下,说话人所使用的语言,简称为隆巴德效应语言因噪声的频谱和强度不同而不同;马尔娃·卡尼尔等人在二种不同噪声下作实验;一种为宽频噪音;另一种为鸡尾宴会上的噪音。

隆巴德效应语言如何随大噪音的音量,频谱分布和交错等参数而改变是个较复杂的问题,现还有人在研究中。

现已知隆巴德效应语言和正常语言的区别有:

已经发现,不仅人类在强大噪音下使用隆巴德效应语言;而且在不少动物中也是这样;如:虎皮鹦鹉,猫,鸡,普通狨猴等数十种动物都有隆巴德效应语言。

Lombard effect 隆巴德效应

Great tits sing at a higher frequency in noise polluted urban surroundings than quieter ones to help overcome the auditory masking that would otherwise impair other birds hearing their song.[1] Although great tits achieve a change in song frequency by switching song types,[2] in other urban birds the change in frequency might be related to the Lombard effect.[3] For instance, in humans, the Lombard effect results in speakers adjusting frequency

The Lombard effect or Lombard reflex is the involuntary tendency of speakers to increase their vocal effort when speaking in loud noise to enhance the audibility of their voice. This change includes not only loudness but also other acoustic features such as pitch, rate, and duration of syllables. This compensation effect results in an increase in the auditory signal-to-noise ratio of the speaker’s spoken words.
