Embodiment

[0076] The nasal and accent measuring instrument of the present invention is connected with the subsequent processing unit through the signal output port 28 . Subsequent processing unit refers to supporting computer software, oscilloscope and so on. Turn on the shell power switch 25 of the nasal and accent measuring instrument, and observe whether the power supply and the low battery prompt indicator light 23 flicker. If the power supply and the low battery prompt indicator light 23 are in a flashing state, then the power supply battery needs to be replaced. If the power supply and the low electricity prompt indicator light 23 show normal, the battery power supplies power to each internal unit after distillation, filtering and voltage stabilization.

[0077] Before using the nasal and accent measuring instrument for measurement, the voice calibration unit 5 can be used for voice calibration. After the tuning switch 24 is turned on, the tuning speaker 20 sends a standard audi...

Abstract

The invention discloses a nasal voice measuring instrument which comprises a nasal voice acquisition unit and a filter amplifier unit. The nasal voice acquisition unit is used for acquiring nasal voice signals. The filter amplifier unit connected with the nasal voice acquisition unit is used for amplifying and filtering the nasal voice signals. The nasal voice measuring instrument is capable of filtering noise in the signals to improve precision in signal acquisition and amplifying the signals at the same time, and is capable of detecting weak information in the signals to solve the problem of signal inaccuracy. The nasal voice measuring instrument can be used with other devices such as computers and software to achieve systematic detection and estimation on speech disorders, and has the advantages of high precision and wide application in clinical applications and scientific research. The invention further provides a measuring method of the nasal voice measuring instrument.

Description

technical field [0001] The invention belongs to the field of medical equipment, and relates to a nasal accent measuring instrument and a measuring method thereof. Background technique [0002] Since the invention of the nasal tester by Fletcher and his assistants in the 1960s, the nasal tester has become the most commonly used instrument for selecting and improving abnormal nasal resonance in the world (see US Patent No.3 of Fletcher et al. , 752,929, whose filing date is August 14, 1973). It detects, measures and compares nasal and oral sounds during speech. The measurements are displayed as calculated "nasalance" sound intensity ratios over a selectable bandwidth. The "Nasogram" chart is used for the different diagnoses of nasal speech abnormalities caused by congenital disorders such as cleft palate, invasive diseases such as myasthenia gravis, and damage to the separation of oral and oral articulations. Accidentally produced by the ability of nasal resonance. These vi...
