Triple noise reduction refers to effectively suppressing the noise caused by the Gaussian pendulum curve, the noise caused by the compression process and the video mosquito noise caused by image flicker, thereby improving the overall effect of the picture and bringing a full High-definition image experience.
Noise reduction, as the name suggests, is to reduce the impact of noise on people. Commonly used methods include: 1. Sound insulation room; 2. Installation of muffler; 3. Sound insulation barrier; 4. Vibration reduction, etc.
1. Sound absorption
Sound absorption and noise reduction is a method of controlling the intensity of noise along the transmission path. The sound absorption effect of objects is ubiquitous, and the sound absorption effect is not only related to the sound-absorbing material, but also to the selected sound-absorbing structure. This technology is mainly used in indoor spaces.
2. Silencer
A muffler is a device that can both allow airflow to pass through and effectively reduce noise. Mufflers can usually be used to reduce the noise transmitted at the entrance and exit of various aerodynamic equipment or along the ducts. For example, mufflers are widely used in noise control of internal combustion engines, ventilators, blowers, compressors, gas turbines, and various high-pressure and high-flow emissions. Different mufflers have different noise reduction principles. Commonly used silencing technologies include resistive silencing, resistance silencing, impedance composite silencing, vibration silencing, lossy silencing, diffusion silencing, etc.
3. Sound insulation
Enclose the noise-generating machinery and equipment in a small space to isolate it from the surrounding environment to reduce the impact of noise on the environment. This approach It's called sound insulation. Sound insulation barriers and sound insulation covers are the two main designs. Other sound insulation structures include: sound insulation rooms, sound insulation walls, sound insulation curtains, sound insulation doors, etc.
