  • For effective soundproofing, the standard method is a double installation: first, attach heavy sound-insulating material (rubber sheets] to block sound, and then attach sound-absorbing material on top to dampen reverberation.
  • Sound leaks out through even the smallest gaps, like a pinhole. Joints and corner gaps between materials must be sealed perfectly airtight using silicone or joiners.
  • Egg carton sponge-type sound-absorbing material is primarily used to dampen internal sound resonance (echo], and may not be sufficient to completely block external noise from neighbors or upstairs.
  • Soundproofing materials are quite heavy. When installing them on ceilings or walls, please reinforce and secure them firmly using strong adhesives and staples to prevent them from falling off over time.
  • If you install it directly over the wallpaper in a rental home, it will be difficult to restore it to its original condition later. We recommend applying masking tape to the wallpaper first and then attaching it with silicone.

Soundproofing/Sound-Absorbing Material Quantity Calculator, Guide to Calculating Quantities for Sound Insulation Materials, Artboards, and Egg Cartons

The key to soundproofing is airtightness. If materials are in short supply and pieces are pieced together haphazardly, sound leaks through the minute gaps, drastically reducing the effectiveness of the soundproofing. If you input the wall area to be treated and the specifications of the sound-absorbing material to be used, we will calculate the precise required quantity to maximize noise blocking performance, taking into account markup rates (losses] and deductions for areas such as windows.

Soundproofing/Sound-absorbing Material Quantity Calculation Formula

It is calculated by dividing the total construction area by the effective area of ​​one sheet of material.

Total quantity required
Required Quantity (sheets] = {(Construction Area - Deduction Area] ÷ Area per Sheet of Material} × (1 + Markup Rate/100]
Standard quantity per m²
Quantity per m² (sheets] = 1 ÷ Area of ​​one sheet of material

Ordering materials becomes much easier if you first determine the basic number of sheets required per unit area (㎡] of the construction space.

Detailed Guide to Calculator Input Items

Please verify the actual measurement data of the construction area and material specifications for an accurate estimate.

1. Construction area width, height

Enter the total width and height of the wall or ceiling where the soundproofing material will be attached. Please take measurements based on the longest section, taking zigzag installation into account.

2. Types and Specifications of Sound-Absorbing Materials

Standard specifications vary for each material. Please enter the width and height of the material to be installed, such as artboard (600x600/1200], egg carton (500x500], and soundproofing material (1000x1000].

3. Surcharge rate and deduction area

A foundation loss of 5–10% is usually recommended, and the area of ​​spaces where materials do not adhere, such as windows or doors, is automatically excluded to increase accuracy.

Expert Know-how and Checklists

These are the key practical points for maximizing soundproofing performance.

  • Double installation of sound insulation and sound absorption materials

    To ensure effective noise blocking, the standard practice for soundproofing is to first attach high-density sound insulation material to the wall to block sound transmission, and then add sound-absorbing material on top to absorb sound resonance.

  • Airtight construction (perfect sealing of gaps]

    Sound leaks out through even the smallest gaps. You must meticulously seal gaps between materials and corners with silicone or specialized joiners to capture even high-frequency sounds.

  • Use dedicated adhesive and reinforcement

    While convenient adhesive products are good, use a combination of silicone and a glue gun on rough walls. In particular, heavy soundproofing materials must be reinforced sturdily during installation to withstand the load and prevent them from falling.

Frequently Asked Questions (FAQ]

  • Q. Will attaching just egg carton sponges block the noise from the next door?
  • A. Sponge-type sound-absorbing materials are primarily used to dampen internal resonance. To effectively block external noise, it is best to install heavy rubber soundproofing materials first, followed by the sound-absorbing material.
  • Q. Can I apply it directly over the wallpaper in a rental house?
  • A. It is possible, but there is a high risk of damaging the wallpaper upon vacating. If restoring the original condition is important, we recommend applying masking tape broadly to the wallpaper before applying the adhesive.
  • Q. Can I use this calculator on the ceiling as well?
  • A. Yes, if you enter the ceiling width and length, the calculation will be the same. However, since there is a risk of falling materials due to their weight during ceiling construction, please select lightweight materials.
