Acoustic isolation rooms/quiet rooms are equipped with the following soundproofing and noise reduction technologies, which are widely adopted and mature, reliable noise reduction methods:

1) Soundproof Room/Noiseless Room Multilayer Wall Sound Insulation Technology: The sound-insulating walls are divided into interior and exterior walls, which are independently designed. The air layer in between forms an "elastic damping layer" to enhance the absorption of reflected sound. The double walls are only connected at the bottom through vibration dampers.

The advantages of this technology: it can increase the sound insulation level.

2) Multi-layer composite soundproofing technology for soundproof rooms/quiet rooms; each layer of the soundproofing wall is composed of different materials to block sounds across a frequency range of 31.5 to 800 Hz with varying intensities. The soundproofing design specifications can reach 30dB. 3) Vibration reduction technology for soundproof rooms/quiet rooms: The entire soundproof room/quiet room is mounted on vibration isolators, creating a "floating" installation. There is no contact between the room's walls and the building's structure around the perimeter and at the top, preventing sound from being transmitted through the building walls.

4) Soundproof/Isolation Room Air Exchange and Noise Reduction Technology: The soundproof room is equipped with ventilation exchange and noise reduction units, as well as noise reduction air outlets. Under test conditions, the internal ventilation volume of the soundproof room reaches an ideal amount, while also preventing the introduction of external noise and the generation of new wind noise.

5) Indoor Composite Sound Absorption Technology: The silent room employs a new composite sound absorption technology, enhancing the sound absorption coefficient and impact resistance, better meeting the testing requirements for high-volume clinics and ensuring stability in sound absorption.
