中文介紹
HS5721型1/1倍頻程濾波器是一種結(jié)構(gòu)緊湊且便于攜帶的儀器，廣泛應(yīng)用于聲學(xué)測量領(lǐng)域。該濾波器與HS5670型、HS5660型聲級計配合使用時，能夠進(jìn)行中心頻率31.5Hz至16000Hz（共10個通帶）的頻率分析。通過面板按鈕手動操作，用戶可以輕松選擇所需的測量頻率。在與聲級計配合使用時，轉(zhuǎn)換聲級計開關(guān)即可直接讀出通帶聲級的值。此外，它還可以與電平記錄儀連接，實現(xiàn)噪聲的自動分析和記錄。
該濾波器具有以下特點：頻率范圍為31.5Hz至16000Hz，包含10個通帶；可以直接連接聲級計的同步輸入/輸出信號，無需外接電纜；頻率轉(zhuǎn)換通過按鍵控制電子開關(guān)完成；在聲級計的“FLAT”特性下進(jìn)行頻率分析時，也可以使用“A”計權(quán)特性；能夠通過串行二進(jìn)制碼與記錄儀同步進(jìn)行頻譜分析；由聲級計內(nèi)部電源供電；按下“GAIN”按鈕可將信號放大20dB，從而讀出更低的聲壓級值。
其主要技術(shù)性能包括：中心頻率有31.5Hz、63Hz、125Hz、250Hz、500Hz、1kHz、2kHz、4kHz、8kHz、16kHz及“ALL PASS”可供選擇；測量范圍大于50dB；中心頻率選擇方式為手動（按鈕）或串行二進(jìn)制碼選擇；中心頻率顯示采用11個發(fā)光二極管指示；尺寸為50mm×100mm×80mm，重量為306g。
HS5721型1/1倍頻程濾波器因其便攜性和高效性，在建筑、航空、機(jī)械制造、環(huán)保、電聲等多個領(lǐng)域都有廣泛應(yīng)用。
English Introduction
The HS5721 1/1 Octave Band Filter is a compact and portable instrument widely used in the field of acoustic measurement. When used in conjunction with the HS5670 or HS5660 sound level meter, it can perform frequency analysis across 10 bands with center frequencies ranging from 31.5Hz to 16000Hz. The frequency to be measured can be easily selected through the panel buttons. When used with a sound level meter, the sound level of the passband can be directly read by switching the sound level meter. In addition, it can be connected to a level recorder to automatically analyze and record noise.
This filter has the following features: a frequency range of 31.5Hz to 16000Hz with 10 bands; it can directly connect to the synchronous input/output signal of the sound level meter without the need for external cables; frequency switching is done through electronic switches controlled by buttons; it can perform frequency analysis in the "FLAT" characteristic of the sound level meter, and the "A" weighting characteristic can also be used when using the filter; it can perform spectral analysis synchronously with the recorder through serial binary code; it is powered by the internal power supply of the sound level meter; pressing the "GAIN" button can amplify the signal by 20dB to read lower sound pressure level values.
Its main technical performance includes: center frequencies of 31.5Hz, 63Hz, 125Hz, 250Hz, 500Hz, 1kHz, 2kHz, 4kHz, 8kHz, 16kHz, and "ALL PASS" are available for selection; the measurement range is greater than 50dB; the center frequency selection method is manual (button) or serial binary code selection; the center frequency display uses 11 light-emitting diodes; the size is 50mm×100mm×80mm, and the weight is 306g.
The HS5721 1/1 Octave Band Filter is widely used in various fields such as construction, aviation, mechanical manufacturing, environmental protection, and electroacoustics due to its portability and efficiency.
