The S14 insert earphones provide high-quality acoustic stimulus delivery while attenuating scanner noise. They are small enough to fit within any headcoil, and can be covered with circumaural muffs for added protection if the coil allows. Replaceable Comply(TM) Canal Tips ensure sanitary conditions.

Frequency response equalization is achieved by pre-filtering stored digital stimuli. Equalization filters are provided and can be used either within Matlab or with a stand-alone filtering program (provided). A small power amplifier is required.
