The Effectiveness of Office “Online Booths” and the Importance of Soundproof Performance

But why are they suddenly so essential? In this article, we’ll dive into the necessity of Online Booths and address the big question regarding “Soundproof Performance” using our proprietary, real-world measurement data (D-value testing).

【Context: Market Trends】
The surge in Online Booth installations across Japanese-affiliated offices in Vietnam is primarily driven by the permanent shift to Hybrid Work post-pandemic. While the frequency of web conferences has exploded, traditional office infrastructures have struggled to keep pace with these modern demands.

【Reasoning: The Growing Necessity】
Office buildings in Vietnam are often vulnerable to sound echoes and lack sufficient acoustic privacy. For expatriates and executives, frequent strategy meetings with the Japan HQ or high-stakes local negotiations require a secure environment—free from interruptions and eavesdropping. Yet, many companies face a dilemma: a chronic shortage of meeting rooms relative to the rising volume of remote calls.

Have you ever been in a headset meeting at your desk, only to have a colleague start a loud phone call right next to you, forcing you to apologize to your client: “I’m sorry, it’s a bit noisy here…”? Or perhaps you’ve had to step outside the office just to discuss confidential HR matters or top-secret projects?

【The Solution: Why Booths are the Answer】
Online Booths solve these “Noise” and “Space” frustrations without the need for large-scale construction. It is the most accessible and effective solution for any office that simply needs “one more meeting room.”

Implementing an Online Booth offers much more than just ‘creating a private room’— it delivers profound strategic and operational advantages.

When you consider the boost in meeting efficiency and the ability to handle high-stakes, confidential tasks without distraction, installing these pods should be viewed as a ‘strategic investment’ in business productivity rather than a mere office expense.

“Soundproof” is a broad term, and actual performance varies significantly between manufacturers. To provide clarity, we are sharing a Sound Leakage Test report from our signature custom-built Online Booths. By using specialized sound sources and precision measurement apps, we ensure a fair assessment that mimics human hearing.

In the Vietnamese market, many products are labeled as “Online Booths” but fail to deliver adequate acoustic insulation. At CRAFTEC, we have undergone continuous R&D and iterative refinements to reach the high-performance structural details we offer today.

• Sound Source: Pink Noise Utilizing “Pink Noise 10min” via YouTube. Pink Noise is a sound that blends frequencies uniformly across the entire spectrum, making it ideal for checking comprehensive soundproof performance from low to high pitches.

• Measurement App: NIOSH SLM We use NIOSH SLM, a highly reliable noise measurement application. This tool accurately captures not just instantaneous volume, but also Equivalent Continuous Sound Levels (Leq) and other critical data.

• Testing Method: Loud Pink Noise is played inside one of two adjacent booths (Booth 1 and Booth 2). We then measure the sound leakage into the neighboring booth to calculate the noise reduction differential.

【Point: Measurement Results & Assessment】 In short, the acoustic performance of our booths has been rated as “Excellent (Very low sound transmission)”.

【Reason: Understanding D-value (Sound Pressure Level Difference) Standards】 Soundproofing is evaluated using the “D-value”, representing the difference between the source room’s sound (L1) and the receiving room’s sound (L2):

• D ≤ 15: Conversations are clearly audible.

• D = 20–25: Conversations are heard but difficult to understand.

• D ≥ 30: Good insulation.

【Example: Real-world Data Details】 Let’s look at the actual measurement results:

• Case 1 (Source in Booth 1): When playing Pink Noise at 77.8dB (comparable to a subway car or shouting), the noise in the adjacent booth dropped to 37.5dB (the level of a quiet library). The D-value recorded was 40.3dB.

• Case 2 (Source in Booth 2): Similarly, at a source of 76.0dB, the leakage was only 38.4dB, resulting in a D-value of 37.6dB.

【Point: What This Means for Your Business】 A score of 37–40, well above the standard D=30, means that even if someone shouts on the other side of the wall, it only sounds like a faint murmur. For normal online meeting volumes, the risk of your conversation leaking out is virtually zero.

Summary In Vietnam’s evolving office landscape, Online Booths are shifting from “nice-to-have” to “essential professional infrastructure.” In fact, over half of the corporate clients whose offices are designed by CRAFTEC have chosen to implement our Online Booths.

Our rigorous Pink Noise test results (D-value 40.3) prove that these are not just booth-style boxes, but “true sanctuaries of silence” backed by verified performance. If you are struggling with “sound leakage” issues, please feel free to reach out for a consultation.
