Method and system are disclosed for automated testing of a patient's hearing. The automated hearing test allows the patient to quickly and accurately test his own hearing with minimal or no assistance from an audiologist or other hearing health professionals. The test prompts and instructs the patient for inputs and responses as needed as needed. The patient can select one or several tests to be performed, including air and bone conduction testing with masking, speech reception threshold, speech discrimination, and tympanogram/acoustic reflex testing. Multiple languages are supported. Data obtained from one test may be used for another test or another iteration of the same test to calculate masking levels. The automatic hearing test also detects ambient noise and can compensate for it in the test results. If a contingency occurs, the automated hearing test is configured to page the operator for assistance.

A rapid screening, threshold, and diagnostic tests for evaluation of hearing includes techniques that are particularly suited for rapid objective hearing screening and evaluation of newborns or other patients who are unable or unwilling to provide reliable subjective responses. The hearing tests may be frequency specific or may evaluate overall hearing ability without special focus on frequency-specific loss. The tests involve the use of novel stimuli, signal processing, signal analysis, and statistical techniques, including the use of ramped stimuli and evaluating the changes that these stimuli evoke in the individual's brain activity at different moments in time.

The systems, methods and associated devices performing diagnostic hearing tests which use a computer network to allow interaction between a test administration site and one or a plurality of remote patient sites. The test can be administered by an audiologist or clinician at a site remote from the patient, in a manner, which can allow interaction between the user and the clinician during at least a portion of the administration of the test. The diagnostic hearing tests can be performed such that they meet standardized guidelines such as ANSI requirements or certification standards and can include distortion product emission level measurements or middle ear compliance measurements.

A digital headset system for use in audiometric testing. The headset system includes a stored calibration reference relating the exact frequency and volume response of each speaker to analog input signals. A microprocessor accesses the calibration reference to determine the required analog signal needed to produce the desired sound. An on-board digital to analog converter generates the required analog signal and transmits it to the speaker. The headset is used with software based audiometric test methods that allow the generation of an electronic user hearing profile. The user hearing profile may be used to re-program an audio emitting device to function in a customized manner. The user hearing profile may be overlaid on a partner hearing profile in order to emulate for the partner how sounds are perceived by the user. The test methods may be self-administered or administered by a healthcare professional.

Methods and apparatus for maximizing speech intelligibility use psycho-acoustic variables of a model of speech perception to control the determination of optimal frequency-band specific gain adjustments. Speech signals (or other audio input) whose intelligibility is to be improved are characterized by parameters which are applied to the model. These include measurements or estimates of speech intensity level, average noise spectrum of the incoming audio signal, and/or the current frequency-gain characteristic of the hearing compensation device. Characterizations of listeners based on hearing test results, for example, may also be applied to the model. Frequency-band specific gain adjustments generated by use of the model can be used for hearing aids, assistive listening devices, telephones, cellular telephones, or other speech delivery systems, personal music delivery systems, public-address systems, sound systems, speech generating systems, or other devices or mediums which project, transfer or assist in the detection or recognition of speech.

The present invention relates to a pure tone audiometer, and more particularly, to a pure tone audiometer with automated masking which is capable of automatically performing air-conduction and bone-conduction hearing tests and automatically performing a masking test, if necessary, so that a person obtains an accurate pure tone hearing threshold without others' assistance. The pure tone audiometer of the present invention can accurately perform the pure tone hearing test with automated masking without assistance from a doctor or an audiologist. Thus, with the pure tone audiometer, people can easily check their hearing ability for prevention and early detection of hearing loss and take swift action to cure hearing loss.

Method and system are disclosed for a multimedia user interface for an automated diagnostic hearing test. The user interface provides a means for a patient to interact with the automated hearing test to complete each test. The patient is given instructions and guidance for every test, and can call the operator at any point for help. Warning messages and progress indicators are provided to help the patient gauge his progress. Such an arrangement allows the patient to test his own hearing with minimal or no assistance from an audiologist or other hearing health professional. The user interface also allows the operator to configure the automated hearing test as needed.

The invention discloses a digital hearing aid loudness compensation method based on frequency compression and movement, which belongs to the technical field of voice signal processing. The digital hearing aid loudness compensation method comprises the following steps of: filtering, and extracting the low-frequency part and the high-frequency part of a signal; compressing and moving the voice high-frequency part according to proportion; simulating a voice signal heard by a patient; designing a four-channel FIR-QMFB (Quadrature Mirror Filter Banks); dividing a frequency range; and carrying out loudness compensation and gain control; and combining voice. The digital hearing aid loudness compensation method is characterized in that the original voice signal is divided into low frequency and high frequency, then, the high-frequency part is compressed and moved to a medium and low frequency range according to proportion, and the overlaid voice signal is subjected to frequency band division and loudness compensation according to a hearing test curve of a hearing impairment patient. Therefore, negative effects brought by carrying out high-gain loudness compensation on the high frequency range in the prior art can be effectively avoided, and the hearing level and the language recognition rate of the patient can be effectively improved.

This invention describes methods of Audio Signal Personalized Enhancement for optimal listening to music. A combination of hearing test, audio signal compensation, and signal processing algorithms are implemented jointly in an audio Device. An audio signal is processed and tuned within the entire range of audible frequencies to actively compensate for both the characteristics of the listening device, and the specific hearing characteristics of the listener, resulting in a much improved music listening experience. A randomized self-test algorithm is used to analyze user's hearing ability in each ear within a preselected dynamic volume range at multiple frequencies spanning the audible spectrum.
