一种利用骨传导刺激诱发听觉反应的新方法被开发出来，用于自由活动的非麻醉动物。在猫和大鼠身上，压电材料要么被螺栓固定在牙科用的丙烯酸颅骨平台上，要么被嵌入其中。为了产生声刺激，使用滴答声和点滴电波形来驱动晶体材料中的振动。对晶体刺激的反应与对空气耦合刺激的反应进行了比较，发现它们实际上是相同的。声学掩蔽消除了反应，表明其他感官模式对反应没有显著贡献。
A new method of eliciting auditory responses using bone-conducted stimuli was developed for use in freely-moving unanesthetized animals. In cats and rats piezoelectric materials were either bolted to or embedded within a dental acrylic skull platform. In order to produce acoustic stimulation, click and pip electrical waveforms were used to drive vibrations in the crystalline material. Responses to the crystal-elicited stimuli were compared with responses to air-coupled stimuli and were found to be virtually identical. Acoustic masking eliminated the response showing there is no significant contribution made to the responses by other sensory modalities.
