General tips for OAE acquisition

The following Smart Note covers general information for the acquisition of distortion product and transient evoked otoacoustic emission responses. The information includes suggested test parameters, as well as guidance for probe placement, for use with SmartDPOAE and SmartTrOAE software.

Estimating electrophysiological threshold using SmartEP

The HL or Hearing Level scale can be used to easily compare the hearing level differences between test subjects in the same population category. In human populations, this corrected scale is usually determined by the acquisition of behavioral thresholds. However, in cases where the population being tested cannot interactively provide threshold information, it may be necessary to find the normal expected ABR hearing threshold using electrophysiological responses. This Smart Note… Read More »Estimating electrophysiological threshold 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
