第1圖為實施例中硬碟測試系統100的示意圖。硬碟測試系統100包括訊號產生器10用於產生控制訊號，喇叭20用於播放單頻音，錄音設備30用於測量音壓，傳輸速率測試伺服器40和硬碟50。錄音設備30包含麥克風，置於硬碟50的位置，用於接收喇叭20所播放的單頻音。傳輸速率測試伺服器40具有硬碟效能測試軟體，例如IOmeter，用於量測硬碟的資料傳輸速率。訊號產生器10可設定頻率區間並自動掃頻。訊號產生器10可於喇叭20的頻率範圍內，例如50Hz至20000Hz，以自動步進的方式控制單頻音，在此同時可用傳輸速率測試伺服器40量測硬碟50的資料傳輸速率（Hard disk I/O throughput），進而找出使硬碟50傳輸性能下降的敏感頻率。這些頻率數據可用在改善系統風扇的設計。FIG. 1 is a schematic diagram of the hard disk test system 100 in the embodiment. The hard disk test system 100 includes a signal generator 10 for generating control signals, a speaker 20 for playing a single-frequency sound, a recording device 30 for measuring sound pressure, a transmission rate test server 40 and a hard disk 50.

These frequency data can be used to improve the design of the system fan.

第2圖是分析振噪影響硬碟效能方法200的流程圖。方法200係用於硬碟測試系統100，且可於訊號產生器10和傳輸速率測試伺服器40設定量測範圍後自動測試。分析振噪影響硬碟效能方法200包括以下步驟：FIG. 2 is a flowchart of the method 200 for analyzing the effect of vibration and noise on the performance of the hard disk. The method 200 is used in the hard disk test system 100 and can be automatically tested after the signal generator 10 and the transmission rate test server 40 have set the measurement range. The method 200 for analyzing the effect of vibration and noise on the performance of a hard disk includes the following steps:

S210：  對訊號產生器10設定一頻率區間；S210: Set a frequency interval for the signal generator 10;

S220：  對傳輸速率測試伺服器40設定該頻率區間；S220: Set the frequency interval for the transmission rate test server 40;

S230：  傳輸速率測試伺服器40量測硬碟50的理想資料傳輸速率；S230: The transmission rate test server 40 measures the ideal data transmission rate of the hard disk 50;

S240：  訊號產生器10控制喇叭20產生一單頻音，該單頻音具有一頻率，該頻率係介於該頻率區間，且該單頻音在硬碟50之位置具有一音壓；S240: The signal generator 10 controls the speaker 20 to generate a single-frequency tone, the single-frequency tone has a frequency, the frequency is within the frequency range, and the single-frequency tone has a sound pressure at the position of the hard disk 50;

S250：  錄音設備30於硬碟50之位置量測該單頻音的該音壓；S250: The recording device 30 measures the sound pressure of the single-frequency tone at the position of the hard disk 50;

S260：  當喇叭20產生該單頻音時，傳輸速率測試伺服器40量測硬碟50的資料傳輸速率；S260: When the speaker 20 generates the single-frequency tone, the transmission rate test server 40 measures the data transmission rate of the hard disk 50;

S270：  若該資料傳輸速率低於一預定值或傳輸速率測試伺服器40無法量測硬碟50的資料傳輸速率，跳至步驟S240，否則執行步驟S280；S270: If the data transmission rate is lower than a predetermined value or the transmission rate test server 40 cannot measure the data transmission rate of the hard disk 50, skip to step S240, otherwise, perform step S280;

S280：  記錄該頻率及使傳輸速率測試伺服器40得以量測硬碟50的資料傳輸速率高於該預定值的音壓。S280: Record the frequency and enable the transmission rate test server 40 to measure the sound pressure at which the data transmission rate of the hard disk 50 is higher than the predetermined value.

在步驟S230，傳輸速率測試伺服器40會在幾乎沒有噪音的環境下量測硬碟50的資料傳輸速率，以找出硬碟50的理想資料傳輸速率。在步驟S240，訊號產生器10可控制喇叭20從步驟S210的頻率區間產生一單頻音以模擬噪音，且每隔一間隔時間就會以自動步進的方式（例如由低頻至高頻或由高頻至低頻）控制喇叭20產生另一單頻音。喇叭20所產生的單頻音之頻率皆介於步驟S210中設定的頻率區間，如此便可在後續步驟中找出並記錄在頻率區間中各個頻率的單頻音不會嚴重損害硬碟50之資料傳輸速率的音壓。In step S230, the transmission rate test server 40 measures the data transmission rate of the hard disk 50 in an environment with little noise to find the ideal data transmission rate of the hard disk 50. In step S240, the signal generator 10 can control the horn 20 to generate a single-frequency tone from the frequency range of step S210 to simulate noise, and it will automatically step by step (for example, from low frequency to high frequency or from low frequency to high frequency) at intervals of time. (High frequency to low frequency) control the horn 20 to generate another single frequency tone. The frequency of the single-frequency sound generated by the speaker 20 is within the frequency range set in step S210, so that the single-frequency sound of each frequency in the frequency range can be found and recorded in the subsequent steps without serious damage to the hard disk 50. The sound pressure of the data transfer rate.

在步驟S270，若資料傳輸速率低於一預定值，或是傳輸速率測試伺服器40無法量測硬碟50的資料傳輸速率，則表示步驟S240的單頻音的音壓太高，會嚴重損害硬碟50之資料傳輸速率，因此步驟S270需要跳回至步驟S240，使訊號產生器10控制喇叭20產生另一單頻音，該另一單頻音的頻率不變，但音壓要降低，如此藉由步驟S240至步驟S270的循環，便可找出在某一頻率下，單頻音不會嚴重損害硬碟50之資料傳輸速率的音壓。當找到此音壓，便可執行步驟S280，以記錄在該頻率下的可容許音壓。In step S270, if the data transmission rate is lower than a predetermined value, or the transmission rate test server 40 cannot measure the data transmission rate of the hard disk 50, it means that the sound pressure of the single-frequency tone in step S240 is too high, which will seriously damage The data transmission rate of the hard disk 50, therefore, step S270 needs to jump back to step S240, so that the signal generator 10 controls the speaker 20 to generate another single-frequency tone. The frequency of the other single-frequency tone remains unchanged, but the sound pressure needs to be reduced. In this way, through the loop of step S240 to step S270, it is possible to find out the sound pressure of the single-frequency sound at a certain frequency that does not seriously damage the data transmission rate of the hard disk 50. When the sound pressure is found, step S280 can be executed to record the allowable sound pressure at the frequency.

使用分析振噪影響硬碟效能方法200的量測結果記錄可如第1表所示。第1表為噪音頻率，硬碟50之位置的音壓與硬碟50之資料傳輸速率的對照表，由此表即可看出硬碟50之資料傳輸速率明顯下降的頻率點。在這些頻率點進行硬碟50之資料傳輸速率測試時，可控制訊號產生器10調降喇叭20所釋放的音壓，即可找出單頻音不會嚴重損害硬碟50之資料傳輸速率的音壓。The measurement result record using the method 200 for analyzing the effect of vibration and noise on the performance of the hard disk can be shown in Table 1. The first table is a comparison table of the noise frequency, the sound pressure at the position of the hard disk 50 and the data transmission rate of the hard disk 50. From this table, we can see the frequency point at which the data transmission rate of the hard disk 50 drops significantly. When testing the data transmission rate of the hard disk 50 at these frequency points, the signal generator 10 can be controlled to reduce the sound pressure released by the speaker 20, and it can be found that the single-frequency tone will not seriously damage the data transmission rate of the hard disk 50 Sound pressure.

由第1表可得知硬碟50之資料傳輸速率在無單頻音的影響下為113.52 IO/s，倘若硬碟50傳輸資料的環境是使用4KB來測試，則113.52 IO/s會等於4KB ×113.52而係454.08KB/s。當音壓存在時，硬碟50的運作會受音頻和音壓的影響而使資料傳輸速率下降。舉例而言，當頻率為1250Hz且硬碟50之位置的音壓為105dB時，資料傳輸速率為111.94 IO/s，假設方法200之步驟S270的預定值是100 IO/s，由於111.94 IO/s超過100 IO/s，屬於可接受的資料傳輸速率，因此可執行方法200之步驟S280，直接記錄頻率1250Hz及音壓105dB。當頻率為1600Hz且硬碟50之位置的音壓為108dB時，資料傳輸速率降為97.8 IO/s，由於97.8 IO/s低於預定值(100 IO/s)，因此要降低音壓，以硬碟50之位置的音壓為95dB執行步驟S240；當硬碟50之位置的音壓為95dB時，硬碟50之資料傳輸速率提升至102.92 IO/s，其係大於預定值(100 IO/s)，屬於可接受的資料傳輸速率，因此可執行方法200之步驟S280，記錄頻率1600Hz及音壓95dB。當頻率為2000Hz且硬碟50之位置的音壓為106dB時，資料傳輸速率降為88.66 IO/s，由於88.66 IO/s低於預定值(100 IO/s)，因此要降低音壓，以硬碟50之位置的音壓為90dB執行步驟S240；當硬碟50之位置的音壓為90dB時，硬碟50之資料傳輸速率提升至102.78 IO/s，其係大於預定值(100 IO/s)，屬於可接受的資料傳輸速率，因此可執行方法200之步驟S280，記錄頻率2000Hz及音壓90dB。當頻率為2800Hz且硬碟50之位置的音壓為100dB時，資料傳輸速率為111.31 IO/s，其係大於預定值(100 IO/s)，屬於可接受的資料傳輸速率，因此可執行方法200之步驟S280，記錄頻率2800Hz及音壓100dB。因此，由第1表可知硬碟的敏感頻率（資料傳輸速率下降最多）為1600~2000Hz。第1表所述之數據僅為舉例，本發明不在此限。It can be seen from Table 1 that the data transfer rate of the hard disk 50 is 113.52 IO/s without the influence of single-frequency audio. If the data transmission environment of the hard disk 50 is tested using 4KB, 113.52 IO/s will be equal to 4KB ×113.52 and 454.08KB/s. When the sound pressure is present, the operation of the hard disk 50 will be affected by the audio and sound pressure and the data transmission rate will decrease. For example, when the frequency is 1250 Hz and the sound pressure at the position of the hard disk 50 is 105 dB, the data transmission rate is 111.94 IO/s. Assuming that the predetermined value of step S270 of the method 200 is 100 IO/s, since 111.94 IO/s More than 100 IO/s is an acceptable data transmission rate. Therefore, step S280 of method 200 can be performed to directly record the frequency of 1250 Hz and the sound pressure of 105 dB. When the frequency is 1600 Hz and the sound pressure at the hard drive 50 is 108 dB, the data transmission rate drops to 97.8 IO/s. Since 97.8 IO/s is lower than the predetermined value (100 IO/s), the sound pressure must be reduced to The sound pressure of the hard disk 50 is 95dB and step S240 is executed; when the sound pressure of the hard disk 50 is 95dB, the data transmission rate of the hard disk 50 is increased to 102.92 IO/s, which is greater than the predetermined value (100 IO/ s), which is an acceptable data transmission rate, so step S280 of method 200 can be performed, with a recording frequency of 1600 Hz and a sound pressure of 95 dB. When the frequency is 2000 Hz and the sound pressure at the hard drive 50 is 106 dB, the data transmission rate drops to 88.66 IO/s. Since 88.66 IO/s is lower than the predetermined value (100 IO/s), the sound pressure must be reduced to The sound pressure of the hard disk 50 is 90dB and step S240 is executed; when the sound pressure of the hard disk 50 is 90dB, the data transmission rate of the hard disk 50 is increased to 102.78 IO/s, which is greater than the predetermined value (100 IO/ s), which is an acceptable data transmission rate, so step S280 of method 200 can be performed, with a recording frequency of 2000 Hz and a sound pressure of 90 dB. When the frequency is 2800Hz and the sound pressure at the hard drive 50 is 100dB, the data transmission rate is 111.31 IO/s, which is greater than the predetermined value (100 IO/s), which is an acceptable data transmission rate, so the method can be implemented In step S280 of 200, the recording frequency is 2800 Hz and the sound pressure is 100 dB. Therefore, it can be seen from Table 1 that the sensitive frequency of the hard disk (the data transmission rate drops the most) is 1600~2000Hz. The data described in Table 1 are only examples, and the present invention is not limited thereto.

實施例中所述的單頻音可用於模擬電腦系統中風扇所產生的振動噪音。第1表中所記錄的測試資料可提供給風扇廠商，而廠商可得知用於電腦系統之硬碟的敏感頻率為1600~2000Hz，在設計系統風扇時便可利用音頻及音壓資料使應用在電腦系統的風扇避開敏感頻率或降低風扇在敏感頻率的音壓，以改善電腦系統的效能。The single-frequency sound described in the embodiment can be used to simulate the vibration and noise generated by a fan in a computer system. The test data recorded in Table 1 can be provided to the fan manufacturer, and the manufacturer can know that the sensitive frequency of the hard disk used in the computer system is 1600~2000Hz, and the audio and sound pressure data can be used when designing the system fan. The fan in the computer system avoids the sensitive frequency or reduces the sound pressure of the fan at the sensitive frequency to improve the performance of the computer system.

綜上所述，本發明之分析振噪影響硬碟效能方法藉由訊號產生器，喇叭，錄音設備和傳輸速率測試伺服器可自動量測在不同噪音頻率下的硬碟資料傳輸速率，可快速有效地找出硬碟敏感頻率及耐受音壓。這些頻率及音壓數據可用在改善系統風扇的設計，進而改善電腦系統的效能。 以上所述僅為本發明之較佳實施例，凡依本發明申請專利範圍所做之均等變化與修飾，皆應屬本發明之涵蓋範圍。In summary, the method of the present invention for analyzing the effects of vibration and noise on the performance of the hard disk can automatically measure the data transmission rate of the hard disk under different noise frequencies through the use of signal generators, speakers, recording equipment and transmission rate test servers, which can be fast Effectively find out the sensitive frequency of the hard disk and withstand the sound pressure.
