How many acoustic panels do you need for an office, restaurant, or meeting room?

Are you wondering how many acoustic panels you need to install in your office, restaurant, classroom, or recording studio?

Until now, you had to consult an acoustics specialist to get an estimate. Today, thanks to our free online acoustic calculator, you can get an accurate estimate tailored to your space in just a few clicks.

What Is an Acoustic Calculator?

An acoustic calculator is a tool that estimates the amount of acoustic treatment required (in square feet or square meters) based on:

• The room dimensions (length, width, and height)

• The existing finishing materials (floor, walls, and ceiling)

• The intended use of the room (office, restaurant, performance hall, etc.)

• The thickness and type of acoustic panels selected

Unlike a simple calculation based solely on room dimensions, our calculator takes into account the sound absorption coefficients of the finishing materials used on the walls, floor, and ceiling. For example, drywall, glass, wood, metal, concrete, and carpet do not absorb sound in the same way. By considering these characteristics, the calculator provides a much more accurate estimate of your actual acoustic treatment requirements.

Why Optimize a Room’s Acoustics?

Poor acoustics can result in:

• Excessive reverberation (unpleasant echo)

• Poor speech intelligibility (listening fatigue)

• Reduced productivity in open-plan offices

• A poorer customer experience in restaurants or performance venues

On the other hand, well-designed acoustics improve comfort, concentration, and the overall user experience.

How Does Our Acoustic Calculator Work?

Our tool is based on standardized formulas that follow acoustic recommendations for different types of spaces (recommended RT60).

The calculator also determines the recommended RT60 (reverberation time) range based on the intended use of your space. Acoustic requirements vary significantly between a meeting room, restaurant, classroom, place of worship, and recording studio. The goal is to achieve the ideal reverberation time to provide optimal acoustic comfort and excellent speech intelligibility.

Simply follow these 4 easy steps:

1. Enter your room dimensions.

2. Select the finishing materials for the floor, walls, and ceiling.

3. Choose the RT60 (reverberation time) appropriate for your room's intended use.

4. Select your desired acoustic panel thickness.

The calculator automatically generates:

• The required acoustic treatment area in square feet (sq. ft.)

• An estimate based on the sound absorption coefficients of the materials already present in your room.

• A recommendation based on the RT60 range appropriate for your type of space.

Example

• Meeting room: 20 × 15 × 10 feet

• Drywall walls, vinyl flooring, and drywall ceiling

• Use: Conference room

• Panel thickness: 2 inches

Result: approximately 100 sq. ft. of acoustic treatment, equivalent to approximately 12 panels measuring 23" × 47".
