METHOD FOR AUTOMATIC DETERMINATION OF AN INDIVIDUAL FUNCTION OF A DPOAE LEVEL
The automated determination of an individual function of a DPOAE level map with p.sub.dp,I=f(L.sub.1, L.sub.2) of human or animal hearing. The method may include reading into a main memory a model function with model parameters of a DPOAE level map, based upon a number of N DPOAE measurements of a stimulation frequency pair with respectively different level pairs in a population (p) of a population of normally hearing subjects, automatically presenting n different level pairs of a stimulation frequency pair via tone output means to an individual and detecting the corresponding DPOAE's of the individual via tone recording means, wherein at least the first level pair is predefined, iteratively adapting the model function to the measured n DPOAE's until an individual function is obtained with individual parameters of a DPOAE level map of the individual, outputting the individual function and/or its individual parameters.

Auditory stimulus for auditory rehabilitation
Generally, a method performed by one or more processing devices includes generating a graphical user interface that when rendered on a display of the one or more processing devices renders a visual representation of an environment and a visual representation of an object in the environment; retrieving an auditory stimulus with one or more auditory attributes indicative of a location of a virtual target in the environment; receiving information specifying movement of the object in the environment; determining, based on the movement of the object, a proximity of the object to the virtual target; adjusting, based on the proximity, one or more values of the one or more auditory attributes of the auditory stimulus; and causing the one or more processing devices to play the auditory stimulus using the adjusted one or more values.
Apparatus and method for determining parameter using auditory model of hearing loss patient
An apparatus and method are provided to determine a parameter using an auditory model of a hearing loss patient. The parameter determination apparatus determines a similarity between a neurogram of a normal subject and a neurogram of a hearing loss patient, and determines an optimal frequency band for the hearing loss patient based on the similarity.
ELECTROCOCHLEOGRAPHY TESTING IN HEARING PROSTHESES
Presented herein are techniques for performing automated Electrocochleography (ECoG) testing using ambient sound signals received by a hearing prosthesis during normal operation (i.e., outside of a clinical setting). In particular, the hearing prosthesis analyzes ambient sound signals to identify portions of the sound signals that are conducive/suitable to the performance of an ECoG measurement (i.e., an ECoG measurement structure). When an ECoG measurement structure is identified, the hearing prosthesis itself performs an ECoG measurement using one or more implanted electrodes.
METHOD TO ESTIMATE REAL NOISE EXPOSURE LEVELS
There is provided a method for determining a noise exposure level associated as the cause of an observed evolution of hearing acuity of an individual of known gender. The method comprises the following steps: 1) providing a first audiogram of the individual measured at age X and a second audiogram of the individual measured at age Y; 2) inputting the individual's gender, age X, and a time period equal to Y−X in a statistical hearing threshold levels evolution prediction formula; 3) calculating projected hearing loss audiograms specific to each of a plurality of possible noise level exposure values, using the prediction formula; 4) comparing a pattern of each calculated projected audiogram with a pattern the second audiogram; 5) selecting the projected audiogram that best fits the second audiogram; and 6) assuming that the noise exposure level value associated with the selected projected audiogram is the noise exposure value that caused the evolution of hearing acuity observed between the first and the second audiograms. There is also provided systems for performing the method and methods for providing services to clients or enabling users regarding determination of real ear noise exposure values.
