What is Sound Wave Reflection? 什麼是聲波反射?

Updated: Apr 16

Remember the first time you discovered the whisper dishes? You can talk and hear to your friend far from you.



Our ancestor discovered this natural phenomena and used in their architecture designs. The design allow one person to do a speech, sing or perform an instrument to the large audiences.



The famous Sydney Opera House concert hall designed and improved by adding reflect panels to beam the sound accurately to the positions. You can find the full article about the details here.



In the offices and restaurants we are doing the opposite to reduce the unwanted noise. A lot of sound absorbing materials are used in the walls to take away the sound. It absorbs the sound so there is no reflected sound bounce back to the listeners.



In the professional recording studio the ceiling and the walls are designed to both reflect and absorb the sound reflection to make sure the music that reach your ears are the same as artist intended.



However, you can not do the professional acoustic treatments or refection design at all your rooms or when you are on trips from home.


Your best alternative choice?

OPSIS II's special algorithm can re-align the reflected sound waves to create 360 degree immersive sound. The reflected sound waves from the surrounding surfaces are re-aligned with OPSIS's original sound waves before it reaches your ears. This is not only can reduce unwanted noises but also recreate sound images that usually take 5 or more speakers to achieve. The OPSIS II gives you 360 degree 3D realistic sound wherever you are. Stay tuned for more information!

您還記得看過科學博物館或公園裡用兩個大盤子反射聲音的耳語盤嗎?當您的朋友站在距離您不遠的另一個耳語盤時,您可以與他們交談並聽到他們的聲音。


我們的偉大的祖先發現了這種自然現象,並將其用於建築設計中,這種設計允許一個人向大批觀眾講話、唱歌或演奏樂器。


著名的悉尼歌劇院音樂廳也使用了這種方法,並通過添加更多的反射板使聲音更準確地投射到聽衆位置上。您可以在此處找到有關詳細信息。


在辦公室和飯店中,我們通過減少聲音的反射以減少不必要的噪音。牆壁上使用了很多吸音材料來減少噪音。



在專業錄音棚中,天花板和牆壁設計成既反射又吸收聲音反射,以確保您聽到的音樂與藝術家想要表達的意念一致。



但是您無法在所有房間或出門旅行時進行專業的聲學處理或音效設計。


另一種方便的替代產品?


OPSIS II的特殊算法可以重新對齊反射的聲波,以創建360度沉浸式聲音。來自周圍表面的反射聲波在您聽到音樂時會與OPSIS的原始聲波重新對齊。這不僅可以減少不必要的噪音,還可以重建通常需要5個或更多揚聲器才能實現的聲音圖像。無論您身在何處,OPSIS II都能為您提供360度3D逼真的聲音,請關注我們更多未來動向!
