Description

Technical Field

[0001] The present invention relates to the field of audiology, and in particular to a subjective audiometric data recording system and an application method thereof. Background Art

[0002] Subjective audiometry is an audiometric method that requires the subject to make subjective judgments on the sound signals (test sounds) they hear and to make behavioral responses. It requires the subject's subjective cooperation and reflects his or her ability to perceive the test sounds. It is also called behavioral audiometry.

[0003] Pure tone audiometry and speech audiometry are currently the most widely used and reliable subjective tests in clinical practice. During the test, the subject makes a subjective behavioral response to inform the operator. Conversely, the operator records the test results by observing the subject's behavioral response. It can be seen that although the test results are obtained based on the subjective behavioral reflection of the subject, they are actually recorded by the operator after his own observation and judgment. This process is likely to be mixed with the subjective impression of the operator, and the test results will become less objective and accurate. In subsequent hearing rehabilitation, if this inaccurate data is used again as a fitting benchmark, it will lead to poor hearing aid fitting results, low satisfaction and other adverse results. Summary of the invention

[0004] The purpose of the present invention is to provide a data recording system for subjective audiometry, which can automatically record data such as the number of times the subject responds, the intensity of the stimulus sound when responding, and the interval time between two adjacent responses. These data can be used to analyze the subject's reaction sensitivity and response quality, and then judge the accuracy of these data, and guide operating technicians to quickly identify useful data, eliminate the interference of bad data, and ultimately improve the accuracy of subjective audiometry results. An application method of the data recording system for subjective audiometry is also provided, which can at least solve one of the above problems.

[0035] Figure 2 An application method of a subjective audiometric data recording system according to an embodiment is schematically shown.

[0036] like Figure 2 As shown, the method applies the above-mentioned subjective audiometry system for hearing test, and the application method is implemented by the following steps:
