Description of the invention: [Technical field to which the invention pertains] a = invention relates to a method and device for preventing hearing loss, and in particular to a hearing protection method and device capable of warning the hearing loss range of a human ear . [Prior Art] As long as people are exposed to noise above 90 decibels, they will feel harsh, and 'the volume of the Cong Walkman can reach m decibels. If I take a long time, I may have temporary hearing impairment. Fashion can be combined with medication to make the hearing gradually recover. If the listener still does not change the original listening habits, the number of hair cells in the inner ear region will continue to decrease, and severe cases will lead to permanent deafness. Although scholars and experts agree that controlling the volume, time and quality of listening headphones is the best protection against hearing, however, it is often difficult for listeners to detect excessive volume, excessive time and difficulty in changing. Most of the research focuses on how to isolate the outside world to preserve vocals or music. Most of the market is selling such anti-noise. There is no effective hearing protection device to prevent hearing loss. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a hearing protection method and apparatus that can alert a human hearing loss range.于疋' The hearing protection method of the present invention comprises the following steps: (a) measuring an audio signal transmitted to the human ear; (13) processing the audio signal for a period of time to generate an average volume, and The volume can be compared with the preset threshold of a protection gate 200917879, and if the volume exceeds the protection threshold, it is judged that a warning is displayed; and (C) is alerted in the warning mode. The hearing protection device is used for an electronic device with a headphone; the hearing protection device comprises a first sensor, a second sensor, a strict module and a warning module.

[Embodiment] The other technical contents, features, and effects of the present invention will be apparent from the following detailed description of the preferred embodiment with reference to the drawings. Referring to Fig. 1, a preferred embodiment of the hearing protection device of the present invention is for an electronic device that is coupled to a headset 2, which in the preferred embodiment is an MP3 player. When the headset 2 is not connected, the electronic device 1 is in the "host listening mode", in which the audio is played in the open space; when the headset 2 is connected, the electronic device i is in the "headphone listening mode" At this time, the audio is directly transmitted to the earphone 2 but not played in the open space, and the sound is transmitted to the human ear by the sealing effect of the earmuffs 21. Referring to FIG. 2, a preferred embodiment of the hearing protection method of the present invention includes the following steps: detecting an audio signal transmitted to the human ear (step 2〇1); generating a period of time: Χ θ frequency signal processing - all capable The volume is compared with the preset volume: the protection threshold value is used to determine whether the mode is -f (step 2〇2) and the warning mode is issued (step 203). In the preferred embodiment, the protection gate weight is a hearing impairment range table set by the Otology Safety and Health Association, as shown in the table: _ Table ~~~~~-- 1 Daily allowance Exposure time (hours) 8 '——-—— 4 -- 2 r--———— 1 ^~ 0.5 L--~_ 0.25 200917879 The average volume can be defined as shown in Equation 1: Equation 1
Leq =Li +l〇l〇g^ 其中，•是一段時間所接收的音量；及.是該段時間 佔一容許暴露時間的比例。 例如，假設使用者接收的音量是在97dBA的環境下經 過1小時，則容許暴露時間8小時的均等音量，帶入公式1 的計算結果為：Leq =Li +l〇l〇g^ where, • is the volume received for a period of time; and. is the ratio of the period of time to an allowable exposure time. For example, suppose that the volume received by the user is 1 hour in the environment of 97dBA, and the average volume of the exposure time of 8 hours is allowed. The calculation result brought into Formula 1 is:
4, = L;. +10 log X. = 97 +10 log i = 97 + (10) * (-0.903) - 88 dBA 8 由前述公式計算結果可知，在97dBA的環境下經過1 小時，相當於音量88dBA的環境下經過8小時的暴露結果 ，已相當接近如表1的90dB A/8小時的容許範圍。 利用公式1，即使是經歷數秒的高音量，也可換算為如 表1的長時間音量暴露結果，例如132dBA的音量歷經0.5 秒，經由公式1的換算可計算出相當於音量84.4dBA的環 境下暴露在8小時，未超出如表1之音量90dBA暴露時間 8小時的容許範圍。 另外，也可使用每曰噪音劑量（Daily Noise Dose)計算 是否超出每日的容許範圍，如公式2: 總嗓音劑量=100% Υα^ (C2 Λπ) + ΙΓ24, = L;. +10 log X. = 97 +10 log i = 97 + (10) * (-0.903) - 88 dBA 8 From the calculation of the above formula, it can be seen that after 1 hour in the environment of 97dBA, it is equivalent to After 8 hours of exposure in a volume of 88dBA, it is quite close to the allowable range of 90dB A/8 hours as shown in Table 1. Using Equation 1, even after a high volume of several seconds, it can be converted into a long-term volume exposure result as shown in Table 1. For example, the volume of 132dBA is 0.5 seconds, and the equivalent of the volume of 84.4dBA can be calculated by the conversion of Equation 1. Exposure to 8 hours did not exceed the allowable range of 8 hours of the 90dBA exposure time as shown in Table 1. In addition, you can also use the Daily Noise Dose to calculate whether the daily allowable range is exceeded, as in Equation 2: Total Arpeggio Dose = 100% Υα^ (C2 Λπ) + ΙΓ2
公式2 其中，Cn是處在一特定音量下的實際暴露時間，及Τη 是該特定音量在該聽力受損範圍的容許暴露時間；若該總 200917879 嗓音劑量超出100%即表示已達警示模式。 】女.¥使用者收聽92dBA的音量3小時，接著調高 為95dBA的音量2小時，最後調高97dBA的音量3〇分鐘 月J 1 两 1〇〇ϋ + ^| + 1 了|| = 100%(0.5 + 0.5 + 0.17) = 117。/〇， 此劑量超出1〇〇%，因此達到了警示模式。 參閱圖3，電子裝置1包括一顯示模組u、一揚聲器 12、—儲存模組13、一電源供應模組14、一警示燈15、一 振動器16及一聽力保護裝置5。 其中，聽力保護裝置5包含一第一感測器5丨、一第二 感測器52、一處理模組53及一警示模組54，處理模組Μ 主要負責控制及協調各元件之運作，包括讀取及播放儲存 模組13的樂曲檔案，及計算處理聽力保護所需的資料等。 其他電子裝置若只有主機收聽模式的則只需第一感測 器5 1 (不需第一感測器52)，只有耳機收聽模式只需第二成 測器52(不需第一感測器5 1)。 為了方便說明起見，以下分別說明聽力保護裝置5於 主機收聽模式及耳機收聽模式時各元件如何運作·· 一、主機收聽模式 處理模組53在此收聽模式是讀取及播放儲存模組13的 樂曲檔案並於揚聲器12發出樂音，於播放樂曲檔案的同時 控制第一感測器51開始偵測樂音的第一音頻訊號5〇1，然 後依據一均能音量方程式（如公式丨）產生一第一均能音量Equation 2 where Cn is the actual exposure time at a particular volume, and Τη is the allowable exposure time for that particular volume in the hearing impairment range; if the total 200917879 voice dose exceeds 100%, the warning mode has been reached. 】 Female. ¥ user listen to the volume of 92dBA for 3 hours, then increase the volume to 95dBA for 2 hours, and finally increase the volume of 97dBA for 3 minutes. Month J 1 2 1 〇〇ϋ + ^| + 1 || = 100 %(0.5 + 0.5 + 0.17) = 117. /〇, this dose exceeds 1%, so the alert mode is reached. Referring to FIG. 3, the electronic device 1 includes a display module u, a speaker 12, a storage module 13, a power supply module 14, a warning light 15, a vibrator 16, and a hearing protection device 5. The hearing protection device 5 includes a first sensor 5, a second sensor 52, a processing module 53, and a warning module 54. The processing module is mainly responsible for controlling and coordinating the operation of each component. It includes reading and playing the music file of the storage module 13, and calculating the data required for handling the hearing protection. Other electronic devices only need the first sensor 5 1 if the host listening mode is only needed (the first sensor 52 is not needed), and only the second sensor 52 is needed for the earphone listening mode (the first sensor is not needed) 5 1). For convenience of explanation, the following describes how the components of the hearing protection device 5 operate in the host listening mode and the earphone listening mode. 1. The host listening mode processing module 53 is the reading and playing storage module 13 in this listening mode. And the music file emits a tone on the speaker 12, and controls the first sensor 51 to start detecting the first audio signal 5〇1 of the tone while playing the music file, and then generates a sound volume equation (such as the formula 丨) according to a uniform energy volume equation (such as formula 丨) First average volume
