It Is True That Pulp Egg Trays is Soundproof ?

Pulp egg trays are made from recycled paper pulp molded into a honeycomb-like structure. While often touted as effective soundproofing materials, their acoustic properties are limited.

Sound Absorption:

Limited Effectiveness – Pulp egg trays exhibit some sound absorption capabilities, primarily in the mid-frequency range. However, their absorption coefficient is generally low, meaning they absorb a small portion of sound energy.

Frequency Dependence – Their sound absorption performance varies significantly with frequency, offering minimal absorption at low and high frequencies.

Soundproofing (Noise Reduction):

Poor Soundproofing – Pulp egg trays have negligible soundproofing properties. They do not effectively block the transmission of sound through walls or ceilings.

Myths and Misconceptions:

Effective Soundproofing – A common misconception is that filling walls or ceilings with egg trays will significantly reduce noise transmission. This is generally not true.

High Frequency Absorption – While some may believe egg trays effectively absorb high frequencies, their performance in this range is limited.

Conclusion:

While pulp egg trays offer some sound absorption capabilities, they are not a suitable solution for effective soundproofing. For serious noise control applications, professional-grade acoustic materials such as mineral wool, rockwool, or specialized acoustic panels are recommended.
