Problems solved by technology

[0006] In order to overcome the above-mentioned technical problems, the present invention proposes a free sound field hearing test system and method, which can solve the problem that the change of the distance during the free sound field hearing test will affect the loudness of the sound signal actually heard by the user, and it cannot be fixed in the actual test process. this distance, making it difficult to effectively calibrate the problem

Embodiment Construction

[0050] In order to make the object, technical solution and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0051] It is easy to understand that it is generally considered that the hearing conditions of the two ears are different. In addition, in order to avoid the mutual influence of the two ears, during the hearing test, the left and right ears are tested separately. When a single ear is tested , usually take certain measures to the other ear to prevent interference to the current test ear. Optionally, earphones playing white noise can be worn.

[0052] The present invention proposes a free sound field hearing test system, comprising:

[0053] a computer device with a sound player and a hearing aid, the computer device and the hearing aid communicating via a network connection;

[0054] The computer device is installed with a test APP. In a possibl...

Abstract

The invention discloses a free sound field hearing test system and method, and relates to the field of hearing test. The method includes: playing a test sound with a set sound frequency and a set sound loudness, defining the sound loudness as the first loudness; receiving the test sound, and calculating the sound loudness of the position of the test sound at the receiving place, Define the loudness of the sound as the second loudness; perform hearing feedback to test whether the sound is heard; D, calculate and output the hearing test result according to the first loudness, the second loudness, the sound frequency and the hearing feedback. Wherein, during the hearing test, according to the user's hearing feedback on whether the test sound is heard, the computer device can be used to reset the loudness or frequency of the test sound for testing. The technical scheme of the invention can accurately obtain the loudness heard at the position of the human ear without being affected by the test distance; and the calibration is performed through the algorithm in the hearing aid DSP, so the accuracy is higher.

Description

technical field [0001] The invention relates to the field of hearing test, in particular to a free sound field hearing test system and method. Background technique [0002] At present, with the popularity of smart phones and apps, a simple hearing test method through mobile phone apps + earphones has emerged. In this method, the testee wears headphones in a relatively quiet environment and operates according to the guidance of the app. The app will play sound signals of different frequencies and loudness, and ask the testee if they heard it. According to the result of the user's selection, the loudness data that the user can hear at different frequencies is obtained, that is, the hearing curve. [0003] First of all, the accuracy of the test results in this way depends on the calibration of mobile phones and earphones, because the hardware of mobile phones and earphones used by users has many changes, which makes calibration very troublesome. [0004] Secondly, when testi...
