    Hollow cone series absorbing materialsIt is a new type of sound-absorbing material with excellent sound absorption performance and wide applications. This article will provide a detailed introduction to the hollow cone series of absorbing materials.

1、 The principle of hollow cone series absorbing materials

Hollow cone series absorbing materials are based on the theory of acoustic porous mediaSound absorbing materialThe principle is to use the movement of air in porous media to absorb sound waves. When sound waves pass through a material, they reflect, propagate, and refract. Due to the porous structure of the material, sound waves are captured and energy loss occurs inside the material, resulting in the absorption of sound waves.

2、 Structure of Hollow Cone Series Absorbing Materials

The structure of the hollow cone series absorbing material is a porous structure composed of many hollow cones. The interior of the hollow cone is air, and the outer surface is covered with special sound-absorbing material. This structure generates a large amount of friction and turbulence within the material, which in turn absorbs sound waves.

3、 Performance of Hollow Cone Series Absorbing Materials

1. High sound absorption performance: Hollow cone series absorbing materials have extremely high sound absorption performance, with a sound absorption coefficient of over 0.99, which can effectively absorb most sound waves.
   

   
   

2. Broadband sound absorption: The sound absorption performance of hollow cone series absorbing materials is not only effective within a specific frequency range, but also can effectively absorb sound waves over a wide frequency range.
   

   
   

3. Lightweight: Hollow cone series absorbing materials have the characteristic of lightweight, with low density, and can be used in situations where weight reduction is needed.
   

   
   

4. High temperature resistance: Hollow cone series absorbing materials have high temperature resistance and can maintain their sound absorption performance unchanged in high temperature environments.
   

4、 The application of hollow cone series absorbing materials has a wide range of applications.

The following are its main application areas:

1. In the field of architecture: used for sound insulation, sound absorption, noise reduction, etc.
2. Aerospace field: used to reduce aircraft noise, vibration, etc.
3. Automotive industry: used to reduce car noise and air resistance.
4. In the field of electronic communication: used to reduce noise in electronic products.

5. Industrial field: used to reduce machine noise, reduce vibration, etc.
   

So the hollow cone series absorbing materials have excellent sound absorption performance and wide application prospects, and are a very promising type of absorbing material.
