環境鬥士又一福音! 可能係目前世界上最細的低音陷阱!
2024年度第一件到港新品 Acoustic Revive RHR-21 登場 !!!!
一提起香港玩 Room Acoustic, 其中一個非常普遍而又最多令客人頭痛的, 就係因為細小的環境下容易發生的駐波 (英：Standing Wave / 日：定在波) 問題. 當你播放音樂時如果發現播到部分的低頻頻段時突然爆響（俗稱好boom）, 中音生硬, 高音乾爭爭等等… 好可能是聆聽空間有駐波的影響所導致。
一般最常見的解決方法是利用低音陷阱（Base Trap) 吸收房間自身所產生的駐波頻段, 對該頻段進行處理. 但一般市販的低音陷阱, 體積都過於龐大, 除了好難偷運入屋之外, 就算比你成功偷運, 一件龐然巨物在家中, “低音陷阱”可能除時會變成”家庭陷阱”.
日本Acoustic revive 在2024年最新推出的 RHR-21, 她可能是目前世界上最袖珍的低音陷阱. 其表面像蓮藕般有25個坑位設計, 是廠方運用亥姆霍茲共振 (ヘルムホルツ共鳴) 理論而特別設計(実用新案番号:2023-003995)的吸音孔, 其特別的排列型態能夠做到可以以一支玻璃樽可樂的體積, 發揮到一般低音陷阱的威力. 廠方特別強調, 細小體積的重要性在於可以在聆聽空間內自由擺放, 更容易找到最佳的位置, 而且不阻地方, 最緊要係令到屋企大老細唔會投訴.
RHR-21表面有25個經電腦精密加工的不同深度坑位, 有效地針對30-100Hz 的低頻進行處理, 除此之外她還能消除聆聽空間中不必要的反射和頻帶偏差, 從而改善音樂播放時的相位特性. 使用後更可改善樂器和人聲的通透度和質感, 獲得更精確的樂器定位, 和廣闊的音場.
RHR-21 的使用方法非常簡單, 可以放置在房間的前牆或後牆的角落, 揚聲器的附近, 音響架的後方等駐波容易積聚的地方, 她就能順利工作. 使用時要留意表面25個坑位中最淺的為中心點 (參考付圖), 第一次使用可按照廠方建議的擺放測試, 找出最好聲的位置, 廠方更建議兩支同時使用, 更能發揮最大威力.

Description:
Another Blessing for Environmental Warriors! Possibly the World’s Smallest Bass Trap!
The first new product of 2024, the Acoustic Revive RHR-21, has arrived!!!
When it comes to room acoustics in Hong Kong, one of the most common and frustrating issues is standing waves, especially in small environments. If you notice sudden booms in the lower frequencies, harsh mids, or piercing highs while playing music, it’s likely due to the effects of standing waves in your listening space.
The most common solution is to use bass traps to absorb the frequencies generated by these standing waves. However, most commercially available bass traps are too bulky, making them difficult to bring into homes. Even if you manage to sneak one in, having a large object in your space might turn your “bass trap” into a “home trap.”
Japan’s Acoustic Revive has launched the RHR-21 in 2024, which may be the world’s most compact bass trap. Its surface features a design with 25 pits, inspired by the Helmholtz resonance theory (Utility Model No: 2023-003995). This unique arrangement allows it to perform with the effectiveness of a typical bass trap while being as small as a soda bottle. The small size is crucial for easy placement in your listening space, making it simpler to find the optimal position without taking up too much room, ensuring that household members won’t complain.
The RHR-21 has 25 precision-engineered pits of varying depths that effectively target low frequencies between 30-100 Hz. Additionally, it can eliminate unnecessary reflections and frequency deviations in your listening space, improving the phase characteristics during music playback. After use, it enhances the clarity and texture of instruments and vocals, providing more accurate instrument positioning and a wider soundstage.
Using the RHR-21 is very simple; it can be placed in the corners of the front or back walls, near speakers, or behind audio racks where standing waves tend to accumulate. The shallowest pit among the 25 serves as the focal point (see reference image). For first-time users, it’s recommended to follow the manufacturer’s placement suggestions to find the best-sounding location. The manufacturer also suggests using two units simultaneously for maximum effectiveness.
