Concern regarding the spread of silver carp (Hypopthalmichthys molitrix) and bighead carp (Aristichthys nobilis) through the Illinois River has prompted the development of a Bio-acoustic Fish Fence (BAFF) to act as an acoustic fish deterrent. The application of this technology has resulted in a need to understand the auditory physiology of the target species, in order to maximise the effect of the barrier in preventing the migration of the non-indigenous carp species into Lake Michigan, whilst minimising the effect on indigenous fish populations. Therefore, the hearing thresholds of 12 H. molitrix and 12 A. nobilis were defined using the Auditory Brainstem Response (ABR) technique, in a pressure-dominated sound field generated by submerged transducers of the type used in the construction of the BAFF system. The results clearly show that these fish are most sensitive to sounds in a frequency bandwidth of between 750 Hz and 1500 Hz, with higher thresholds below 300 Hz and above 2000 Hz.
对鲢鱼（Hypopthalmichthys molitrix）和鳙鱼（Aristichthys nobilis）通过伊利诺伊河扩散的担忧促使人们开发了一种生物声学鱼栅（BAFF），作为一种声学鱼类威慑装置。这项技术的应用使得有必要了解目标物种的听觉生理学，以便在最大限度地发挥屏障阻止非本地鲤鱼物种迁移到密歇根湖的效果的同时，尽量减少对本地鱼类种群的影响。因此，在由BAFF系统建设中使用的那种水下换能器产生的以压力为主的声场中，使用听觉脑干反应（ABR）技术确定了12条鲢鱼和12条鳙鱼的听力阈值。结果清楚地表明，这些鱼对750赫兹至1500赫兹频率带宽内的声音最为敏感，在300赫兹以下和2000赫兹以上阈值较高。
