Notched Noise masking using SmartEP

Notched noise masking is an ipsilateral masking noise with special characteristics, more specifically, a gap in the frequency spectrum, usually corresponding to the same frequency as the stimulus. This type of noise can help isolate frequency regions in the cochlea and aid in evaluating acoustic nerve function. This Smart Note covers topics such as suggested electrode placement, stimulus and acquisition setup parameters, and analysis. Notched noise masking is available as… Read More »Notched Noise masking using SmartEP

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

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.

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.

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.

ABR Hearing Screening with PetScreener

The following Smart Note covers the basics concepts for use of the PetScreener software for the acquisition of Auditory Brainstem Responses, with may help diagnose certain auditory conditions in pets and other animals. Information includes suggested guidance for electrode placement, test protocol creation, and analysis.

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.
