Assuming you mean occupation units, then the answer is no. You'd be lucky to get 4dB reduction by adding sound absorber to both rooms. Which would interfere with their natural acoustic properties anyway.
A sound barrier is what is needed, and the appropriate sound isolation between units would be about 55dB or better.
This will require several inches of concrete, or a double-wall construction of plaster board of about 25mm equivalent of board in each wall. With a double wall system - not connected to each other than at the periphery, and without any perforations.
[And assuming there are no flanking paths such as through a common ceiling plenum.]
Spray materials are useful for reducing the reverberance in a space, and might decrease the noise level by up to 15dB in a pretty ideal situation. If the space between the double walls above had some sound absorber (fibreglass, or other light weight fibrous material) in the cavity, that would improve the sound isolation by 5dB or so. [As the small space between the walls would not be very reverberant.]

EzraYes, spray insulation can help reduce noise transmission between units by filling gaps and blocking sound vibrations. However, for optimal noise reduction, additional soundproofing materials such as acoustic panels or barriers may also be needed. It's important to consider the specific noise issues and consult with a professional for tailored solutions.

How do you make a volcano out of spray insulation?
To make a volcano out of spray insulation, you can shape the insulation foam into a cone or volcano shape and let it dry. Once dry, you can paint it to resemble a volcano and create a crater at the top for the eruption effect. Be sure to follow safety precautions and use proper ventilation when working with spray insulation.
What is the best wall insulation for cold climates?
The best wall insulation for cold climates is typically foam insulation, such as rigid foam or spray foam. These types of insulation provide high levels of thermal resistance, helping to keep the cold out and the warmth in during winter months.
What is the best type of insulation?
The best type of insulation depends on the specific needs of the space being insulated. Common types include fiberglass, cellulose, spray foam, and rigid foam. Factors to consider when choosing include cost, R-value, moisture resistance, and installation requirements.
How much does it cost to have someone install spray foam insulation?
The cost of installing spray foam insulation can vary depending on factors such as the size of the area to be insulated, location, and the contractor's rates. On average, the cost range is between $1.50 to $3.50 per square foot. It's best to get quotes from multiple contractors to find the best price for your specific needs.
Is there a spray on insulation made for bare copper wire?
Not that I know of. When insulation is applied to wire it is extruded so that the insulating material is uniform around the conductor. Without this uniformity the conductors insulation factor would vary and the wire would have to be rated at the lowest reading factor when tested with a high voltage. Even when splicing a wire, the electrical code states that the insulation covering the splice has to be brought up to or surpass the insulation factor that is supplied by the manufacturer of the wire.
