Auditory Brainstem Responses acquisition using SmartEP

Learn the process of using the SmartEP software for the acquisition of click evoked ABR waveforms. This Smart Note includes information about electrode placement, acquisition parameters, and peak markings. This guidance applies for the Duet, USB, USBLite, and Solo hardware platforms.

Acquiring Tone Burst ABR with SmartEP

The following Smart Note covers some suggestions for test settings for acquiring ABRs elicited by Tone Burst stimuli, when using the SmartEP software. These settings can be used with the Duet, USB, USBLite, and Solo hardware platforms.

Acquiring Vestibular Evoked Myogenic Potentials using SmartEP

Vestibular evoked myogenic potentials (VEMPs) are short-latency electromyograms (EMGs) recorded via surface electrodes from muscles in the neck or below the eye, in response to acoustic stimuli presented at relatively high levels. VEMP testing for normal saccular/IVN function, when combined with the right battery of tests, can provide valuable diagnostic information about conditions such as Meniere‚Äôs disease, vestibular labyrinthitis, Tullio phenomenon, and more. This Smart Note describes suggested electrode placement,… Read More »Acquiring Vestibular Evoked Myogenic Potentials using SmartEP

Bone Conduction using SmartEP

Bone Conduction testing can help determine the amount and type of hearing loss at specific frequencies, (i.e. hearing threshold), and the presence of any air-bone gap. ABR Bone Conduction testing can provide information about existing conductive hearing problems in the ear canal or middle ear. This Smart Note outlines some suggestions for the use of SmartEP to acquire bone conduction ABR in the Duet, USB, and USBLite platforms.

Evoked potential masking in SmartEP

When stimulating one ear for the acquisition of evoked potentials, it is possible that the response from the non-test ear may be inadvertently considered to be the response from the test ear. The effects and contribution of the non-test ear response will depend on the level of stimulation it receives. White noise may be delivered to the non-test ear to eliminate, or mask, any possible contributions from the non-test ear… Read More »Evoked potential masking in SmartEP

Acquiring Electrocochleography responses using SmartEP

Electrocochleography may be used to diagnose some vestibular and auditory conditions, such as Meniere’s disease or perilymphatic fistula. This Smart Note describes the methodology for acquiring ECochG responses, including the different types of electrodes that can be used, suggested acquisition settings, and instructions on obtaining the SP/AP ratio as well as the area ratio. ECochG can be acquired by using the Duet and USB platforms. The USBLite and Solo platforms… Read More »Acquiring Electrocochleography responses using SmartEP

Suggested Electrode Montages for a 2 Channel Opti-Amp

The following Smart Note covers some suggestions for electrode montages when using the 2 channel optical amplifier for the Universal Smart Box platform. Includes descriptions and images of usual electrode placements for use while acquiring auditory evoked responses such as ECochG and ABR.
