Detection of tinnitus sound frequency using the EEG and generation of masking sound for tinnitus

本研究的目的是通过脑电(EEG)来客观识别耳鸣音的频率。为了诊断引起耳鸣的疾病，有必要知道耳鸣患者所听到的频率类型，但目前还没有有效的方法来客观识别耳鸣的声音。因此，我们的目标是利用脑电来识别耳鸣的频率。作为本研究的第一阶段，我们考察了受试者在听不同纯音时，脑电是否存在差异。如果存在差异，我们测试是否可以根据声音的频率对脑电数据进行分类。结果，我们发现了两种可能性。一种可能性是，当受试者听到不同的纯音时，脑电的变化不同。另一种是脑电可以根据声音频率进行分类。

The purpose of this study is to recognize the frequency of tinnitus sounds objectively by electroencephalogram (EEG). In order to diagnose disorder causing tinnitus, it's necessary to know what type of the frequency that a per-son with tinnitus hears is.However, there are no effective methods to recognize the tinnitus sounds objectively. Therefore, we aim to recognize the frequency of tinnitus tone by using EEG. As the first stage of this research, we investigate whether there are differences among EEG when subjects listen to various pure tones. If the differences exist, we test whether the EEG data can be classified according to the frequencies of sounds. As a result, we found two possibilities.One possibility is that EEG changes differently when subjects listen to various pure tones. The other one is that EEG can be classified according to sound frequencies.
