Definitions

  • the present application relates to hearing aids having adjustable frequency response characteristics, and more particularly, to a system which optimizes the frequency response characteristics of a hearing aid for a particular user.
  • the hearing threshold of an individual is measured by one skilled in the art, typically an audiologist, using a variety of sounds, including pure tones and warble tones, and an audiometer. The result is displayed in an audiogram to show the difference in the hearing threshold for the individual and that of a normal hearing listener at 6 to 8 audio frequencies provided by the audiometer. Additional information is collected to characterize the sensitivity of the individual to loud sounds. This combined information is a measure of the individual's dynamic range of hearing. Various protocols or formulas (such as the Half Gain rule, NAL, and POGO) have been used to define the desired hearing aid performance that would best serve the impaired individual. The hearing aid(s) that most closely matches the desired performance are then selected by the dispenser. In the fitting step, the dispenser fine tunes the adjustable features in the hearing aid to achieve the best match to the desired performance.
  • the dispenser fine tunes the adjustable features in the hearing aid to achieve the best match to the desired performance.
  • the prior art hearing aid fitting adjustment procedure can be quite long and tedious, and its accuracy is limited because it is only guided by the fitting protocols and the experience/training of the dispenser to interpret the results of the work list test. While hearing loss has some typical patterns addressed by the fitting protocols, hearing loss is a highly specific condition that varies greatly from one individual to another such that the fitting protocols are not very accurate. As hearing aid technology has advanced with programmable and digital hearing aids, the range and number of parameters that can be electronically adjusted have increased. Fitting protocols have not developed as rapidly as hearing aid technology, and the fitting time has increased significantly, leading to sub- optimized performance. Summary Of The Invention
  • the present invention is directed to a computer system method an apparatus for optimizing and automating the fitting of hearing aids based on speech material (not tones) as the input source to measure the performance of the individual using the aid.
  • Figure 1 illustrate a flow diagram of the overall fitting process of the present invention
  • Figure 1 A illustrates a more detailed flow diagram for the determination of an imputed inverse transform, as used in the fitting process of Figure 1 ;
  • Figure IB illustrates a more detailed flow diagram of the optimization process as used in the fitting process of Figure 1 ;
  • Figure 2 illustrates a hearing impaired individual training the speech recognition engine (SRE) to learn to recognize words dictated by the individual as read from the SRE computer monitor;
  • SRE speech recognition engine
  • Figure 3 illustrates the hearing impaired individual with relevant hardware arrangement
  • Figure 4 illustrates a count of words in an error list as the optimization process proceeds.
  • the overall fitting process begins by having a hearing impaired subject train a voice/speech recognition engine (SRE) computer to recognize words as read from a visual presentation by the SRE on a computer monitor training screen. Subsequently, the dispenser fits a programmable hearing aid on the hearing impaired subject and connects the hearing aid to the program adjust module, such as Arthur, which is also resident in the computer.
  • SRE voice/speech recognition engine
  • a computer system 10 for optimizing and automating the fitting of hearing aids based on speech material (not tones) as an input source to measure performance of a hearing impaired individual using the hearing aid is illustrated in Figure 3.
  • the computer system includes, as resident software, an SRE module, a Arthur module, an imputed inverse transform module and an optimization module.
  • speech material consisting of nonsense sentences or un-related words from a word list that are very rich in frequency content and replete with time and amplitude variations is stored in the memory of the computer system 10.
  • the stored speech material is presented aurally by the computer system 10 by means of a speaker 12 to the hearing impaired individual wearing an electronically adjustable hearing aid 14.
  • the hearing aid 14 is connected to the computer system 10 by a cable, or some form of wireless data transfer.
  • the individual identifies the words that are heard by repeating them back into the computer system 10 via a microphone 16 (Fig. 2), which then compares this input to original speech material and lists the incorrect words in an error file in the computer system 10.
  • the computer system 10 calculates an imputed inverse transform for a digital (DSP) aid and guides the adjustable parameters within the imputed inverse transform in a programmable DSP aid in an optimization routine to reduce the error list to a minimum through repeated trials.
  • the computer system 10 can also adjust the parameters in a fixed program DSP aid or an analog aid in an optimization routine to reduce the error list to a minimum through repeated trials.
  • the fitting Since the optimization routine is based on mathematical concepts, such as the Simplex algorithm or those used in multi-dimensional servo control systems, the fitting is highly time efficient, accurate and independent of the experience of the dispenser. A further benefit is that the fitting is completely automatic, leading to lower hearing aid distribution cost.
  • the hearing impaired subject repeats the speech material into the microphone 16 connected to the SRE module, a voice/speech recognition engine that is a part of the computer system 10.
  • Keyboard entry or touch screens might also be used to enter the subject's repeated speech material into the computer system 10, but many subjects are not skilled with this form of data entry.
  • Another party, such as the dispenser could enter data, but this would not be automated and would not lower the cost of dispensing.

Abstract

L'invention concerne un système permettant d'optimiser les réglages d'une prothèse auditive, ce système comprenant notamment un ordinateur (10). Ce système fonctionne (12) à partir d'un contenu vocal composé de phrases dépourvues de sens, ou de mots sans aucun rapport les uns avec les autres, tirés d'une liste de mots, ces mots étant riches en composantes fréquentielles et remplissant des variations temporelles et d'amplitude. Un système informatique (10) permet de présenter oralement le contenu vocal susmentionné à un individu malentendant, portant une prothèse auditive (14) réglable électroniquement. Cet individu répète les mots, ledit système informatique (10) permettant de comparer les mots ainsi répétés au contenu vocal original, de manière à identifier les mots incorrects, stockés dans un fichier erreur. Ce système examine les mots n'ayant pas été correctement identifiés et utilise les préconnaissances de leurs composantes fréquentielles et de leurs variations temporelles et d'amplitude, pour calculer la transformées inverse présumée pour une prothèse numérique (DSP).
