What is a silent booth and how does it work?

A silent booth is a freestanding enclosed structure built with dense, layered walls and internal sound-absorbing materials. Its job is to reduce the amount of sound that travels between the inside and outside of the booth. The underlying physics are straightforward: sound is a pressure wave, and the combination of wall mass and porous internal materials dissipates most of that wave energy before it passes through to the other side. A booth does not eliminate sound entirely. It reduces it by a measurable number of decibels, determined by the construction and materials used.

Two functions are worth keeping separate, because they are often confused:

• Soundproofing means stopping sound from passing through the booth walls in either direction. This depends on mass, material density, and the absence of gaps.
• Acoustic treatment means controlling echo and reflections inside the booth, so the sound the user hears is clean and free of reverb.

A well-designed office booth does both at once: a dense outer wall stops sound from leaving or entering, and absorptive inner layers keep audio quality high for the person inside. A booth is not a desk partition or a glass divider. It is a self-contained structure with its own floor, walls, ceiling, and door, all engineered to interrupt sound transmission paths.

One expectation to set clearly from the start: no booth produces absolute silence inside. What it produces is a measurable drop in sound level, and how large that drop is depends on the construction choices made.

How many decibels of reduction can you realistically expect from a silent booth?

The realistic range for an office booth is 30 to 50 dB, depending on construction, materials, and the acoustic conditions of the surrounding space. That number only means something when you know the measurement standard behind it. Framery, for example, publishes a 30 dB figure for their products measured under ISO 23351-1, which measures speech level difference DS,A. This is a different metric from the Rw or STC values used for ordinary wall panels. Without a matching standard label, two figures from two brands cannot be compared directly. As a practical reference point: normal conversation outside a booth runs around 60 dBA. A 30 dB reduction brings the level inside the booth down to roughly 30 dBA, comparable to a quiet library.

To put that range into concrete terms:

• 30 dB reduction: speech outside the booth is no longer intelligible word-for-word from inside. Speech privacy is achieved for standard office use.
• 40 dB reduction: outside sound is reduced to a faint hiss that does not interfere with concentration.
• 50 dB reduction: the interior feels significantly quiet, approaching conditions suitable for voice-over work or basic podcast recording.

Silent Box isolation figures fall in the 35 to 50 dB range depending on the material and construction option chosen. These numbers should always be read alongside the measurement method used, otherwise comparisons with other brands that apply different standards will be misleading.

The practical takeaway: for speech privacy in an open-plan office, a 30 dB reduction is sufficient. For serious audio recording, tighter construction and on-site measurement are needed.

Three silent booth sizes and when to use each

Silent Box comes in three standard sizes. Each one ships as a fully fitted unit, not a bare shell that needs to be equipped separately.

All prices are exclusive of VAT. Installation is available as an add-on service for Rp 2,000,000.

The 220 cm height is a practical advantage that tends to get overlooked in comparisons. Many booths and pods in the global market sit in the 222 to 230 cm range, and some require a minimum ceiling height of 240 cm to install. At 220 cm, Silent Box fits more easily into offices with low ceilings or where ductwork hangs below the structural ceiling.

For a size reference: the Silent Box 4-person unit has a floor area of 3.60 square meters. Four-person meeting pods from global manufacturers average around 2.87 square meters. That difference is not a superlative claim, just a number to help you picture the working space inside.

The three sizes above are a starting point, not a hard limit. Dimensions can be customized to match an existing space. Full variant details and customization options are on the Silent Box product page.

Why ventilation is the most overlooked factor when choosing a booth

A sealed enclosure with no designed air circulation will cause CO2 to build up and temperature to rise within 15 to 20 minutes. Users who overheat or feel short of air will stop using the booth, and the investment goes to waste. This is not a theoretical risk. It is what happens with many low-cost booths that lack an adequate ventilation system.

Silent Box uses a quiet exhaust system mounted in the ceiling. There is a trade-off worth understanding:

• An exhaust that runs too fast cools the booth more quickly, but it adds mechanical noise inside and reduces isolation effectiveness.
• An exhaust that runs too slowly does not replace air fast enough, particularly in a single-person booth where the volume is small.

Good ventilation design balances both requirements: enough air exchange without fan noise that disrupts the user. This is one of the components that separates a booth that remains in active use for years from one that ends up as a storage cupboard. For a more technical explanation of the principles behind this system, read why booth ventilation is designed to run quietly.

When a silent booth makes more business sense than a permanent build-out

This is the question that tends to surface once buyers see the price, and the answer depends on the office situation, not on product preference.

A booth is the better choice when:

• The office is in a leased building and structural renovation is not permitted. A booth does not touch the building’s walls, floor, or ceiling, so no renovation permit is required.
• The need for privacy is concentrated at a few points, not across an entire floor. Installing two booths is far more efficient than building two permanent rooms.
• The budget needs to be predictable. A booth has a fixed price. A construction project has a budget that can expand when unexpected site conditions are found.
• There is a realistic chance of moving offices within two to three years. A modular booth disassembles and reassembles at the new location. A permanent room stays behind.

A permanent build-out is the better choice when:

• Isolation requirements are very high, for example a professional recording studio that requires detailed acoustic measurement and multi-layer construction.
• The area needing acoustic control is large, such as an entire floor or several rooms at once.
• The building is owner-occupied and renovation is unrestricted, making construction cost a sound long-term investment.

A booth is not the right answer for every situation. Choosing correctly starts with understanding the specific requirements of the space and the building. If you have already decided on a booth and want to work out how many units you need, read how to calculate the number of booth units required.

What the building needs to have ready before the booth is delivered and installed

This part is often left out of booth buying guides, but logistics preparation determines whether delivery goes smoothly or stalls in the building lobby.

Three things need to be confirmed before the booth ships:

1. Freight elevator capacity. The single-person Silent Box weighs approximately 160 to 200 kg. Confirm this figure with building management before locking in a delivery date. If the building’s freight elevator has a lower weight limit, the installation team will need to adjust the sequence in which components are brought up.
2. Corridor and door widths along the delivery route. An assembled booth is wider than a standard doorway. Because Silent Box uses a modular frame, components are delivered separately and assembled on site. Even so, the route from the loading point to the installation spot needs to be checked, including corridor widths, fire doors, and tight corners.
3. Floor load confirmation with building management. This is especially relevant for upper floors. Building management may request the unit weight before approving installation. Coordinate this in advance to avoid delays on installation day.

Silent Box production takes 14 to 30 days from order confirmation. Details on what happens between order confirmation and dispatch are covered in booth production and delivery timelines. Because the booth is assembled on site, delivery is available anywhere in Indonesia. For logistics information outside the Greater Jakarta area, see the Silent Box delivery and installation page.

Frequently asked questions before ordering a silent booth

Does a silent booth actually block sound, or does it just reduce it?
No booth blocks 100 percent of sound. What happens is a measurable reduction in sound level, not complete elimination. A well-built booth reduces sound by 30 to 50 dB depending on construction and materials. The practical difference between “reduction” and “isolation” comes down to how large that drop is and whether someone outside can still follow the conversation inside. For speech privacy in an open-plan office, a 30 dB reduction is enough to make the content of a conversation unintelligible from outside the booth.

What is included in the price of a silent booth?
The Silent Box price covers a fully fitted interior, not a bare shell. Included as standard: three-layer fabric-wrapped acoustic panels, ceiling exhaust system, LED lighting, power outlets and switches, wooden flooring, and a wall-mounted desk. Installation is available as an add-on for Rp 2,000,000. All prices are exclusive of VAT.

Can a silent booth be relocated when the office moves?
Yes. Silent Box uses a modular frame that can be disassembled, moved, and reassembled at a new location. This is one of the main reasons businesses in leased offices choose a booth over a permanent build-out: when the lease ends, the booth moves with you and no investment is lost to renovation that stays behind.

Does the building need to verify floor load capacity before the booth is delivered?
Yes, especially for upper floors. The single-person Silent Box weighs approximately 160 to 200 kg. Beyond floor load, you should also confirm the freight elevator capacity and the width of corridors and doorways along the delivery route. Sort this out before the delivery date so installation day runs without delays.
