Works for mitigating noise problems which adversely affect comfort, psychology and in particular health of individuals, have gained importance. In terms of design, noise levels of household appliances can be improved to a certain extent. In the stage, the way to minimize noise levels is take arrange certain safeguards on the path sound advances from its source to a user. Said safeguards are known as sound insulation and are realized by suitable insulation materials and their designs. Designs are known, which prevent sound transmission from source to receiver in desired frequency bands by means of insulation plates comprising sound damping members accommodating metamaterials. What is implied by said metamaterial insulation plate is designs obtained by means of adding metamaterial units arranged with given spaces in between to a flat insulation plate, acting as inhibitor filters in different frequency bands and preventing sound transmission from source to receiver. However, desired extent of sound insulation cannot be provided in the state of the art.
State of the art European patent application no. EP2237700 discloses a silencer design in which specific frequency values can be damped by varying its size.

When a plurality of sound damping members are placed side-by-side on the insulation plate, effective insulation is provided by means of the bodies abutting each other so as not to leave a gap in between.
In an embodiment of the invention, the insulation plate comprises a sound damping member having a pentagonal prism shaped body and two feet connected to each other such that their cross-section forms an inverse V-shape, connected to the body at their ends coupled to each other. In this embodiment, the body and the feet are preferably produced integrally. The V- shape of the feet enables the feet to form a lattice-shaped gap-free structure when a plurality of sound damping members are placed on the insulation plate.

In the preferred embodiment of the invention, damping capacity of the insulation plate is enhanced by selecting the body depth ( Lmass) and the foot depth (Lf0ot) within the stated range. Damping capacity is measured by the provided sound transmission loss due to absorption of the sound waves reaching surface. Sound transmission loss value reaches up to approximately 50 dB by means of the invention.
In an embodiment of the invention, the household appliance comprises a flexible insulation plate. When the insulation plate is placed in the household appliance, it assumes the shape of the empty space where it is placed, thereby realizing a gap-free insulation. In addition, its flexible structure enables using the insulation plate on various household appliances.
In an embodiment of the invention, the insulation plate comprises sound damping member made of polyamide material. Particularly Durable polyamide (Duraform PA) material is preferred in this embodiment. Low-cost of the Duraform PA material enables producing the insulation plate in a low-cost manner. Materials other than polyamide material may be used in other embodiments of the invention. For example, abs, plastic, rubber, silicone, metal, alloy, melamine foams and sponge-like materials may be used.
In an embodiment of the invention, the household appliance comprises an insulation plate. In this embodiment, the household appliance comprises at least one fan or a motor generating noise. The insulation plate positioned proximate to a fan or a motor in the household appliance, enables the sound waves emitted from the fan or the motor to be absorbed by the sound damping member.
