What are the advantages of mobile soundproofing?

Acoustic insulation box (production: Eiffel Acoustics) is mainly used to test the acoustic noise level of electroacoustic components and electronic and mechanical products. Such as small motors, audio and other equipment.

The difference between it and the soundproof room is that the soundproof box occupies a small size, the quality is lighter, the soundproof effect is better than the soundproof room, and it is easy to move, so choose the right soundproof box for different occasions.

Therefore, there are strict standards for the production process and material selection of soundproof cabinets. Due to the relatively high requirements for sound insulation of soundproof boxes, the design of soundproofing boxes is generally a three-layer structure type.

The shell of the soundproof box is made of 2mm thick high-quality cold-rolled electrolytic steel plate and multi-layer damping soundproofing materials, the exterior is sprayed with environmentally friendly paint finish, and the inner layer has sound-absorbing materials.

The selection of materials for mobile soundproofing devices objectively requires high density and high quality, and at the same time, materials of different materials are selected, and to a certain extent, different materials have different sound insulation for sound waves in different frequency bands; When choosing building materials of the same material of the speaker, the same thickness should be avoided in order to effectively avoid the generation of resonance at the same frequency.

The area ratio and the height of the cabinet of the soundproof box (construction: static ring environmental protection) are the reasons that affect the sound insulation effect of the soundproof box. The sound-absorbing tip of the soundproof box is a special sound-absorbing structure for anechoic chambers and semi-anechoic chambers.

When selecting various types of sound absorbers, it is not only necessary to understand the performance of the sound absorbers, but also to install them correctly, so as to obtain high sound absorption, low cost, economic and practical effects.

Soundproof box and silent box are independent cabinets, with relatively small space and can be movable; The soundproof test space designed for the product and product manufacturing workshop is soundproofed and sound-absorbing in the soundproof room to make it a small and quiet environment.

Overview of the advantages of soundproof cabinet customization, the laboratory test soundproof box is mainly used to be placed in the laboratory, the surrounding environment is relatively quiet, there is good background noise, the ambient noise is under 70db a, and the effect of local noise can be tested in the soundproof room 25db a. It has good sound insulation effect, sound insulation box, easy disassembly and assembly, perfect ventilation and air conditioning system, and three-dimensional suspension type.

Soundproofing is used to isolate machines from all kinds of noise. But it's not entirely like that. There are many kinds of soundproof boxes, there are test soundproofs, soundproofing soundproofs, and test soundproofs are not used to isolate various noises, but to test the sound performance of the product.

To ensure that the cabinet of the soundproof box can have a relatively stable moving characteristics, the surrounding vibration damping springs need to be strictly and accurately at the same horizontal height, so that the deviation requirements of the bottom and top of the vibration isolation springs on the horizontal section will be better.

According to the cabinet structure: it can be divided into sealed speakers, inverted speakers, labyrinth speakers, sound wave tube speakers and multi-cavity resonant speakers. Labyrinth enclosure is named after the transmission line of classical electrical theory, and behind the loudspeaker there is an acoustic duct made of sound-absorbing siding, the length of which is 1 4 or 1 8 of the required wavelength of the low-frequency sound.

Theoretically, it attenuates the sound waves coming from behind the cone to prevent them from reflecting off the open end and affecting the sound radiation of the woofer, but in practice the transmission line loudspeaker has a slight damping and tuning effect, increasing the sound output of the speaker near or below the resonant frequency, and reducing the amount of stroke while enhancing the bass output. Usually the sound ducts of this kind of speaker are mostly stacked in a labyrinth, so they are also called labyrinth or curved paths.

The main functions and scope of application of the soundproof box to make a mobile style: the soundproof box provides a soundproof detection environment for the noise inspection of the product, also known as the shielding box, and the soundproof box is to test the noise of the product in a certain sound environment.

In addition to the sound-absorbing system, the soundproof box must also be equipped with soundproof doors, windows, ventilation systems, electrical systems, etc. Sound insulation and noise reduction use the four sides and the top surface to absorb sound, and the bottom layer of the sound removal method to complete the low noise environment inside. Its background noise floor value is not more than 35-40db in sound insulation and noise reduction.

Soundproof cabinets are usually used to isolate most of the noise interference sound, and provide a soundproof detection environment for noise inspection of electronic components.

The general soundproofing effect is outdoor noise: 80dB, indoor noise 45dB, and the soundproof cabinet is suitable for small electronic components in terms of test environment.

The soundproof box is to test the noise of the test product in a certain sound environment, such as: the test product requires that when the external noise is 70 decibels, the environment in the box reaches 30 decibels for product testing.

The structure of the soundproof box mainly includes the box, absorbing materials, filters, hosts and other materials, the absorber materials and filters are mainly to absorb the electromagnetic waves in the box to prevent internal and external interference, and the host is mainly to control the switch and other functions of the shielding box.

The static ring environmental protection soundproof box is made of mobile and can be moved to the place where the product needs to be tested, reducing the need for simultaneous construction of multiple places and saving space.
