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
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 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.
