Abstract

The invention discloses a portable audiometer with an automatic calibration function, which comprises a tablet computer, a core processor, a Bluetooth module, a digital-to-analog conversion module, avolume audio controller, an audio amplifying circuit and an earphone, an application program for hearing test is installed in the tablet computer, the core processor is connected with the tablet computer through the Bluetooth module, and the Bluetooth module is connected with the digital-to-analog conversion module through the earphone. Wherein the core processor is used for transmitting test datain an application program to the core processor, the core processor receives the test data and outputs a corresponding frequency signal to the digital-to-analog conversion module connected with the core processor, and the digital-to-analog conversion module converts the frequency signal into an audio signal and transmits the audio signal to the volume audio controller; and the volume audio controller performs volume control, transmits the volume to the audio amplifying circuit, amplifies the volume by the audio amplifying circuit, and transmits the volume to the earphone for output. The tester has an automatic calibration function, can enable the hearing detector to maintain accurate audio signal frequency and sound pressure level, guarantees accurate hearing test results, and is light, small, exquisite and convenient to carry.

Description

technical field [0001] The invention relates to the technical field of hearing detection, in particular to a portable audiometer with automatic calibration. Background technique [0002] Hearing test equipment is commonly used by otolaryngologists to test hearing. The existing hearing test does not have a self-calibration function. After long-term use, due to the aging of equipment components or improper operation, the output signal accuracy and sound pressure level will deviate. The hospital itself does not have the ability to calibrate, and it takes a long time to send it back to the manufacturer or give the relevant organization a re-calibration. Contents of the invention [0003] The object of the present invention is to provide a portable audiometer with automatic calibration, which can automatically calibrate the output frequency and sound pressure level, so as to obtain more accurate test results. [0004] In order to achieve the above object, the present invention...
