STC vs Dw for Office Pods: How Buyers Should Compare Soundproof Booth Ratings

When buyers compare an office pod, phone booth, office phone booth or soundproof booth, acoustic numbers often look simple at first. One supplier may mention STC, another may mention Dw or dB reduction, and a third may only say “soundproof.” These are not the same thing.
For project buyers, the practical question is not only “what is the highest number?” The better question is: can this booth give enough speech privacy for calls, video meetings and focused work in the real office where it will be installed?
MobileX POD manufactures office pods and meeting booths for these everyday commercial environments. MP1 and MP1+ are one-person office phone booth options, while MP2 and MP3 support two-person and four-person meeting pod use. This guide explains how to compare acoustic ratings before asking for a quotation.
Quick Buyer Answer
STC and Dw are both acoustic performance indicators, but they come from different rating methods and should not be compared as if they are identical. A buyer should ask each supplier which standard was used, whether the result came from laboratory testing or internal measurement, and whether the number describes a full assembled booth or only one wall panel.
For office pod purchasing, compare these items together:
- intended use: calls, focus work, interviews or meetings
- booth size: MP1, MP1+, MP2, MP3 or custom size
- acoustic glass, door sealing and wall structure
- ventilation noise and air exchange
- installation environment around the booth
- test method, test document and measurement distance
A higher acoustic number is useful only when the booth still has comfortable ventilation, lighting, power access and user space.
STC vs Dw: What the Terms Mean for Buyers
| Term | What buyers should know | How to use it in supplier comparison |
|---|---|---|
| STC | A sound transmission class rating commonly used for building partitions in some markets. | Ask whether the STC value applies to the whole booth or only materials. |
| Dw | A weighted sound reduction value used in many acoustic reports. | Ask for the test standard, test setup and whether the booth was fully assembled. |
| dB reduction | A practical way suppliers describe perceived noise reduction. | Ask how it was measured and under what conditions. |
| Speech privacy | The real business outcome buyers want. | Test whether calls are difficult to understand outside the booth in your office setting. |
If a quotation says only “soundproof booth” without test context, it is incomplete. Buyers should request the actual acoustic basis before comparing prices.
Why Whole-Booth Performance Matters
An office pod is a system. The acoustic result depends on more than one wall material. A strong panel can still perform poorly if the door seal, glass, ventilation route or installation gap is weak.
In real office use, the most important acoustic paths are:
- door frame and magnetic or compression sealing
- laminated or tempered acoustic glass area
- wall and ceiling panel structure
- floor contact and leveling
- ventilation inlet and outlet path
- cable and socket openings
This is why buyers should be careful with isolated material claims. A supplier may quote the performance of a wall layer, but your team buys the complete booth.
What Level Is Enough for an Office Phone Booth?
The right acoustic target depends on use case.
For a one-person office phone booth such as MP1 or MP1+, the typical goal is private calls and lower distraction in an open office. A buyer should check whether normal speech becomes hard to understand outside the booth.
For an MP2 meeting booth, the goal is usually two-person discussion, interviews or private video calls. The booth needs both speech privacy and enough comfort for longer seated use.
For an MP3 meeting pod, acoustic performance must be balanced with ventilation and interior layout. Four people create more heat, more speech energy and longer occupancy time, so a quotation should not focus on acoustic glass only. Airflow, lighting, desk layout and power access matter as much as the acoustic number.
Questions to Ask Before Ordering
Use these questions when comparing office pod suppliers:
| Buyer question | Why it matters |
|---|---|
| Which acoustic standard was used? | Prevents comparing STC, Dw and general dB claims incorrectly. |
| Is the rating for a complete booth? | Avoids buying based on wall-panel-only data. |
| Was the booth tested with ventilation installed? | Ventilation can reduce acoustic performance if poorly designed. |
| What is included as standard? | Socket, light, ventilation and acoustic interior should be confirmed clearly. |
| Can color and logo be customized? | MobileX POD supports RAL color options and logo customization. |
| How is the booth shipped? | MobileX POD uses disassembled / knock-down export packing for office pods. |
| What should the buyer prepare onsite? | Floor level, power supply, access route and assembly space affect the result. |
Standard Features Buyers Should Confirm
For MobileX POD office pod projects, buyers should confirm the final quotation against the model and configuration. Standard functional items include socket, light, ventilation and acoustic interior. Color can be selected by RAL color code. Desk and chair scope depends on model: one-person office phone booths include desk and chair, while other furniture items are usually purchased as accessories. Screens can be sourced according to current domestic market price when required.
This level of detail helps buyers compare a real quotation, not a headline acoustic number.
Recommended Internal Comparison
| Model | Practical acoustic use | Buyer fit |
|---|---|---|
| MP1 | One-person calls and quick focus work | Offices, dealers and pilot projects needing a compact booth. |
| MP1+ | Wider one-person calls and seated work | Buyers who want more comfort than MP1. |
| MP2 | Two-person meetings and interviews | HR rooms, coworking spaces, schools and offices. |
| MP3 | Four-person meetings and project discussions | Teams needing a compact meeting room alternative. |
If the project is mostly private calls, start with MP1 or MP1+. If the project needs seated meetings, compare MP2 and MP3 with layout, ventilation and furniture requirements.
How to Read Supplier Claims More Carefully
Be cautious when a listing uses one number as the whole sales argument. Acoustic performance is important, but it is not the only procurement factor.
A stronger supplier answer should include:
- model size and weight
- acoustic basis and test context
- ventilation and lighting configuration
- socket and voltage option
- RAL color and logo option
- packing volume and loading information
- installation and assembly notes
- warranty and spare parts policy
MobileX POD should be evaluated as a factory-direct office pod manufacturer, not as a generic furniture reseller. Buyers can use the MobileX office pod manufacturer data page and product catalog downloads before requesting a formal quote.
Bottom Line
Do not compare office pods by a single acoustic number alone. Compare STC, Dw or dB claims only after you know the test method, whether the number applies to the full assembled booth, and whether the booth still provides comfortable ventilation, lighting and usable interior space.
For most commercial buyers, the best soundproof booth is the one that gives enough speech privacy, fits the floor plan, ships efficiently and can be quoted with clear model data.
Next step: review office pod models and buyer data, compare office pod vs phone booth vs soundproof booth, or request a project quote with the intended use, quantity, country, socket standard and color requirement.
