With this calculator you can determine just the right amount of acoustical coverage you'll need to effectively treat your space. Ranges are displayed as minimum to recommended. Minimum coverage will provide adequate acoustical performance, while recommended coverage will provide significantly better performance than the minimum. A common practice is to begin with the minimum coverage and then deploy any additional coverage as needed.
For your convenience, we also display examples of the calculated coverage, translated into popular panel sizes such as the 4'x2', 4'x4' and 8'x4'.

In my daily line of work, I regularly use software to calculate acoustic parameters, like the sound reduction index of partitions. But as I use these tools, I couldn't help but worry about what happens in the stomach of the software. So I did what any (in)sane physicist would do, and start digging into the software-reference list. And to my surprise, not much was available, and hardly no way for me to verify the software calculations in an excel sheet of my own.
My app is called IsoCal and is a prediction tool for calculating the sound reduction index of single walls with no cavity and double walls with a cavity between the leafs. It is possible to design walls with multiple leafs and different cavity connections (timber studs, steel, double studs, etc.), different porous sound absorption material in the cavity of a double wall and predict the sound reduction index given as a Rw value in decibels [dB]. IsoCal comes built in with a catalog of well known material and porous material to use for designing the wall for optimal sound reduction.
Also, I added in a calculator for calculating the absorption coefficient of porous absorbers with an airgap behind it, and before you say. "yeah yeah, this already exists on a website". I raise you with this "does it have an extension of the porous absorption model, which follows ISO 10534-1:2001 in order to calculate the diffuse field. huh? Don't think so!"
TLDR: I developed an app that calculates the Sound Reduction Index of single and double panel walls, as well as a calculator for the absorption coefficient of Porous absorbers. The app is available on App Store.
As sound waves travel through the air a small portion of the energy is converted into heat depending upon the atmospheric temperature and humidity, however the amount is only significant with high frequencies and long distances.
Saflex SoundPro is an online glass performance calculator that can be used to evaluate laminated glass configurations for sound damping properties. It has a simplified user interface that allows the selection of single number acoustic ratings or the configuration of common glass constructions. Tested and/or estimated performance results are delivered.
The calculator was developed to allow users to compare conventional polyvinyl butyral (PVB) and acoustic PVB tri-layer interlayer technologies to determine the best laminated configuration for specific glazing applications. All values are supplied as glass only and do not consider the incorporation of the glass into glazing systems.
The calculator features various glass thicknesses and configurations with Saflex PVB interlayers. The software will deliver performance information and allow for a PDF report to be generated detailing the glass configuration including interlayer type and thickness, single number acoustic ratings and for tested configurations, one-third octave band data and test variables.
When registered, you can use SoundPro to either calculate sound dampening properties based on a particular glass configuration, or by using the new Product Target mode. The Product Target mode makes it very easy to identify the best acoustic glazing solutions by starting out by considering the performance targets that need to be met (using global standards of STC, OITC, and Rw). Both methods return a detailed report including acoustic ratings, test details, a sound transmission loss chart, glazing configuration details, and other information.
INSUL is a software for calculating the sound insulation of walls, floors and ceilings. Results are predicted in 1/3 octave bands and weighted values. INSUL is currently available in version v9.0 with a multi language user interface and is developed by Marshall Day Acoustics.
In commercial construction, acoustical design and performance continue to take on an increasing role in code requirements and industry guidelines. This is particularly true for healthcare facilities, schools and multifamily dwellings, where the benefits of sound control for occupant productivity, privacy and health must also be integrated with fire-rated wall assemblies that ensure proper egress and life safety.
The STC rating is determined through a standardized test defined by ASTM International. The test involves subjecting the wall assembly to a range of sound frequencies and measuring the sound reduction across those frequencies.
Designing for sound transmission through wall partitions can be challenging because of the amount of variables in how sound travels, including structure-borne sound, airborne sound and flanking sound.
"The capabilities of Strength Lab AI goes far beyond the complexity of known calculations for sound insulation values of glass systems and is tangential to safety-relevant aspects due to the assessment of the load-bearing capacities of the glazing. Until now, such statements could only be achieved by expensive numerical simulations, which are usually not used in practice due to the long computing times and increased modeling requirements," says Dr. Michael Kraus, CEO of M&M Network-Ing, which exclusively developed the AI apps for Kuraray.
We have created this sound absorption coefficient calculator to help you determine the sound-absorbing property of a material. Measuring the sound absorption coefficient is significant for materials where the value is not already determined, and you might be looking to try combinations of new materials.
In this article, you will learn how to calculate the sound absorption coefficient for various materials using the sound absorption coefficient formula. If you don't know it already, you can find out the sound absorption coefficient and why knowing its value is significant for implementing soundproofing systems in any living or working area.
We consider the sound absorption coefficient as a measure for assessing the effective sound absorption by any material. Its value ranges from 0 to 1, with 1 being the perfect absorber.
The second method is total room sound absorption.
You have the option of entering the multiple surfaces present in the room in terms of their surface area and the absorption coefficient values of each surface. The calculator can take input for up to 10 different surfaces.
The third method is the average sound absorption coefficient.
The average sound absorption is calculated using the total absorption of the room and the total surface area in the room in square meters (m2m^2m2) .
Besides these various calculations, you can view α\alphaα (sound absorption coefficient) for some common materials. All you need to do is select yes from the given options, and you will be able to see a list of different sound-absorbing materials and their coefficient values.
The numeric value of the sound absorption coefficient helps understand how effectively any material can block out or absorb sound. The best sound absorbers are materials with sound absorption coefficients (α\alphaα) close to one. As mentioned previously, our sound absorption coefficient calculator allows three different methods to calculate α\alphaα values in different scenarios:
For example, if you have 0.9 W/m2 and 0.3 W/m2 as your absorbed and incident sound intensities, then all you have to do is divide them, and the result would be α\alphaα = 0.3. It means that the material is a relatively poor sound absorber.
When you calculate the total sound absorption of a room, where you have multiple surfaces that you're using to soundproof that room, you need the surface area and the absorption coefficient for each material.
