Ultrasonic absorbing materials

Ultrasonic suction material is a material that can absorb, weaken or suppress ultrasonic transmission. They are usually composed of two parts: sound -absorbing materials and waveguide materials.

Sound absorption materials are the main components of ultrasonic suction materials. It can convert ultrasonic energy into other forms of energy, thereby weakening or eliminating the transmission of ultrasonic. Common sound absorption materials include:

1. Foam material: The foam material is composed of many small bubbles. These bubbles can vibrate when the ultrasonic is passed, thereby absorb ultrasonic energy. Foam materials have good sound absorption performance and light structure.

2. Pole materials: Pores of pores usually contain a large amount of small pores. These pores can weaken the ability of ultrasonic transmission. The sound absorption effect of porous materials mainly depends on the geometric shape and size of the pores.

3. Film material: The film material has greater flexibility and thinner thickness. It can absorb ultrasonic energy by placing a proper film on the ultrasonic transmission path.

Wave guide materials are used to guide ultrasonic propagation. It usually uses materials with low attenuation and high communication speed, such as metal, polymers and ceramics. Wave guide materials can transmit ultrasonic energy from the source to sound -absorbing materials and reduce energy loss.

Ultrasonic suction materials are widely used in the field of engineering, especially in terms of acoustic isolation, noise control, ultrasonic detection, etc. They can effectively reduce the transmission distance and reflection of ultrasonic waves, thereby improving the sensitivity and accuracy of the system.
