Abstract: Un dispositivo o un procedimiento para análisis de reflectancia acustica de los componentes de un oído involucra dirigir al canal del oído, ondas acusticas que cubren una gama de frecuencias que incluyen frecuencias de resonancia de componentes del oído tales como membrana timpánica. Se realizan mdiciones sin someter a presion el canal del oído y el contacto entre el dispositivo y el oído no requiere ser hermético al aire. De acuerdo con esto, el paciente no experimenta esencialmente incomodidad por el uso del dispositivo. El dispositivo detecta y combina las ondas incidente y reflejada para producir lo que se denomina una curva de reflectancia acustica. La forma de una region de la curva de reflectancia acustica se mide electronicamente a fin de obtener un indicador de la condicion del oído, que substancialmente es independiente de una línea de vision entre una fuente de sonido y la membrana timpánica. Este indicador se base en una medicion de la característica de resonancia o libertad de movimiento de la membrana timpánica u otro componente del oído que se analiza. Una medicion tal es la velocidad de cambio de la reflectancia acustica con respecto a la frecuencia. Ya que la resonancia tipicamente provoca que aparezca un nulo en la curva de reflectancia acustica, esta medicion de la velocidad de cambio es particularmente informativa si se mide alrededor del nulo. La velocidad del cambio que se mide alrededor del nulo puede presentarse como una medicion de ángulo, una medicion de gradiente o pendiente, una medicion de ancho u otra forma de medicion de la forma del nulo. En una modalidad, las pendientes más empinadas a ambos lados de un nulo se emplean para definir un ángulo, aquí denominado un gradiente espectral. El diagnostico de una patología de oído tal como una presion anormal o presencia de fluido en el oído medio o esta pérdida de oído de audicion conductora, puede basarse en esta medida solamente. Debido a que la velocidad de cambio de una medicion de reflectancia acustica es relativamente constante para un oído determinado, independientemente de la calidad de la línea de vision a la membrana timpánica, el efecto, de haber, de entrenamiento del usuario en estas mediciones, se reduce significativamente. De acuerdo con esto, el procedimiento y dispositivo de la invencion son utiles en muchos tipos de situaciones de diagnostico con respecto a la patología del oído, pero particularmente en aquellas que involucran clasificacion de los oídos de jovenes y niños, para patologías tales como otitis media incluso por personal no entrenado.

Abstract: A non-invasive, external ear canal electrode (2) and connector (20) therefor useful for transmitting sound stimulus to an ear canal and for conducting electrical signals picked up from the ear canal epidermal surface. The electrode comprises an electro-conductive tube (2) having resilient plastics foam elements (8,10,12) attached to the end to be placed in the ear. One foam element (10) is electro- conductive and impregnated with an electrolytically conductive medium, and the cells of the other sound absorbing elements are filled with air. Stop means (44) projecting from the electrode limits the depth of insertion. The connector has a housing recess (24) into which the electrode can be removably inserted and retained by a spring (34) which electrically connects the electrode with a connector (36). An audio signal passage (42) in the connector communicates with the electrode tube (2).

Abstract: A method and apparatus for diagnosing pathologies of the ear, particularly pathologies such as otitis media, directs into the ear canal (290) a sequence of acoustic waves covering a range of frequencies from a few hundred Hz. to several kHz. and determines the presence or absence of resonance when the incident and reflected waves are combined. The measurements are made without pressurizing the ear canal (290) and it is not required that the contact between the instrument and the ear be air-tight. Accordingly, essentially no discomfiture of the patient results from use of the instrument. The requisite measurements are made quickly (of the order of tens of milliseconds) and thus the distorting effects of patient movement are effectively eliminated. An improved version of the instrument is completely self-contained and hand-held and has the form of a "tee" in which the resonant frequency and amplitude are visually indicated by means of horizontally and vertically disposed arrays of light-emitting diodes (414 and 416).

Abstract: A system and method for measurement of ear conditions utilizing a test signal. The apparatus includes a wave guide (16) having a proximal and distal end. The distal end is connected to a probe tip (18), which may be fabricated of a semi-rigid material or rigid material and may further be a material transmissive light. The probe tip (18) is sized so as to fit at least a portion of the probe tip (18) within the ear canal (38). The wave guide (16) further includes an acoustic energy source (14) disposed substantially at the proximal end for generating a test acoustic wave in response to a source signal. The wave guide (16) further includes an acoustic energy detector, for example a microphone (20), for detection of reflected acoustic energy and generation of an electrical signal in response. The apparatus is controlled by a processor. The processor is adapted to generate the source signal which will preferably contain pseudo-random noise. The processor is further adapted to receive the detected signal from the acoustic energy detector and to generate a condition signal related to the ear condition in response to the detector signal and the source signal. The condition signal may be utilized to control a video display (43), a printout device (44), or any other device capable of conveying to the operator the ear condition. The apparatus may be further adapted to view the ear while testing by including a lens (22) at the proximal end and a light source (24) toward the distal end of the wave guide (16). Also disclosed is a method for measurement of ear conditions.

Abstract: @ Sound generating apparatus, for example for use as an audiometer, comprises a series resonant circuit (12-17) having electrode terminals (10) for application to a patient so as to include the impedance of the patient in the resonant circuit. An oscillator (10-26) supplies to the resonant circuit a carrier signal at a high frequency determined by the resonant circuit. A modulator (22) amplitude-modulates the carrier signal at an audio frequency provided by an adjustable- frequency generator (27-29). An attenuator (23) is controllable to adjust the amplitude of the carrier signal to a selected value. An A/D converter (58, 31) generates a first digital representation of the actual amplitude of the carrier signal, and a manually-operable selector (32, 33) provides a second digital representation of a selected value of the carrier signal amplitude. A central processor (31), responsive to the first and second digital representations, controls the attenuator to maintain the amplitude of the carrier signal at the selected value. The audio modulation frequency is similarly controlled by comparing a digital representation of the desired frequency, as set up on a manually-operable selector (59, 60), with a digital representation of the actual frequency. The current and modulation frequency selectors are preset stepwise by manual rotation of rotors (40) having detents formed by cooperating magnetic elements (46, 47) which establish rest positions corresponding to steps to which the selector may be set. Each selector has spaced- apart segments (42) which cooperate with a pair of optointerruptors (43, 44) to feed signals to a logic circuit (48-57) which generates stepping pulses and pulses indicating the direction of adjustment of the selector.
