Beyond 0~20 Hz (To Hear What You Can't Hear)

《Beyond 0~20Hz》作品主要是以0~20赫茲(Hz)（人耳聽不見的正弦波音頻）為音源，從「數位控制」0~20赫茲聲音的音頻與響度，所產生的喇叭「類比錯誤」變化，來重新建構新的聲音，帶領人們聽覺「失感」的重新感知。
．
作品使用八個重低音喇叭（0~20 赫茲音頻在一般音響喇叭、耳機、擴大機無法擬真地傳播這些超低頻聲波）。喇叭在此作品所扮演的不是聲音傳輸的發聲器，而是在數位控制0~20 赫茲的音頻與響度變化，喇叭的物理性錯誤所發出的聲音，喇叭像是發聲的樂器，不同的喇叭有其獨特的音色。
．
從這一連串由「數位控制」音頻與響度的「類比錯誤」喇叭發聲的實驗，架構出全新的聆聽經驗，並對於聲音發送處理有著創新的實驗。同時，喇叭在不同音頻的振動也帶給視覺上無名的顫動；實驗手段的粗暴卻也直接揭露了聲響活力的肉感脈衝。

Beyond 0~20Hz proposes to bring the imperceptible to human perception. It aims to achieve this by using 0-20Hz (i.e.the inaudible sound frequencies of sine waves) as the main source of sound, while digitally controlling the frequenciesand loudness of sounds of 0-20Hz. It is so that the device would generate 'analog faults' on the loudspeakers that leadto the production of new forms of sound.
．
Beyond 0~20Hz utilizes a total of eight subwoofers. (By and large, stereo devices such as loudspeakers, headphones orpower amplifiers do not support infrasonic sounds, i.e. those of 0-20Hz.) It should be noted that the subwoofers used inBeyond 0~20Hz are not intended to function as the sound transmitter. Instead, as the variations of sound frequency andloudness are digitally controlled, the physical errors may trigger sounds from the subwoofers themselves, effectivelymaking the subwoofers a music instrument in its own right. As such, each of the eight subwoofers would generate itsown distinctive sound.
．
As a series of attempts to digitally control the sound frequency and loudness are made, Beyond 0-20Hz constructsnew forms of hearing experiences, as well as experiments ways in which sounds can be transmitted, by means oftriggering the 'analog faults' that would prompt the subwoofers to generate sounds. In the meanwhile, the variationsin the sound frequency also lead to visible vibration of the subwoofers which can also be perceived as a visual thrill;on the other hand, the abrasiveness embedded in the way Beyond 0-20Hz attempts such experiments can also be seento inadvertently reveal another sense by which the vitality of the sounds can be perceived: that is, through the touchof the sound-generated pulse.
