Embodiment Construction

[0025] The present invention will be described in detail below in conjunction with the accompanying drawings and examples.

[0026] The method for measuring inner ear noise intensity of the present invention is a subjective measurement method based on repeated auditory judgments of patients, and the specific steps of the method of the present invention are as follows.

[0027] 1. Based on a sound combination of a certain reference loudness and frequency, the stimulus sound is generated at a constant level with different variable loudness interval levels.

[0028] For a preset reference loudness L1 and frequency F1, such as loudness L=70dB, frequency 2000Hz, for different loudness intervals ,Such as The initial value of 40dB generates two sound levels at a constant level, sound level 1 (A1) and sound level 2 (A2). The frequency of the overall level of sound level 1 (A1) and sound level 2 (A2) is F1 Hz, the intensity of the average level is L1 dB SPL, and the specific loudnes...

Abstract

The invention discloses an internal ear noise intensity measurement method based on variable loudness control by combining psychophysics on the basis of auditory perception and attention mechanisms of two ears. The method includes firstly, establishing sound stimulation for experimental measurement, and subjecting a sound combination with specific reference loudness and frequency to loudness control in two ways including constant horizontal sound stimulation and variable horizontal sound stimulation; then, as for each loudness control way, enabling a subject to judge experimental stimulation through playing of a target sound group for experimental measurement and determine which segment of the two kinds of horizontal sound stimulation is higher in average intensity by key pressing; finally, analyzing and fitting numerical values by acquiring sound stimulation evaluation data under combinations different in reference loudness and frequency and different variable loudness levels, and obtaining internal ear noise intensity measurement results according to a fitting formula.

Description

technical field [0001] The invention relates to the technical field of acoustic testing, in particular to a method for measuring inner ear noise intensity based on variable loudness adjustment. Background technique [0002] Tinnitus is a subjective auditory experience produced by individuals in the absence of responsive external sound stimuli, and is a common symptom caused by auditory dysfunction. Studies have pointed out that about 70% of people with hearing loss have tinnitus at the same time. The incidence of tinnitus is extremely high, and some tinnitus has seriously affected the quality of life of patients, causing emotional disorders such as anxiety and depression, and even causing suicidal thoughts in patients. For many years, the effectiveness of tinnitus treatment has been limited by a lack of understanding of the overall mechanism of tinnitus. [0003] Subjective tinnitus refers to "symptoms of sound sensation in the ear or in the brain when there is no external...
