I. Application of Audiometric Booth Products:

Otorhinolaryngology diagnostics, ear examination at health check-up centers, sound field audiometry, behavioral audiometry, hearing aid fitting shops, etc.

II. Specifications for the Soundproof Room Background Noise:

Outdoor background noise level is ≤55dB(A); the background noise level to be achieved in the listening room: double-layer <25dB(A) meets the requirements of the new standard GB/T16296.1-2018 for air conduction and bone conduction in China.

Three: Design Principles:

Overall suspended installation in the sound field listening room, with comprehensive anti-vibration features. The walls are treated with multi-sound technology, providing excellent sound insulation, noise reduction, and absorption capabilities. The studio is equipped with forced ventilation and air exchange, ready for immediate use upon installation. The design is scientific, safe, and stable, with a strong resistance to deformation in the material structure. The main modules are assembled in a modular fashion, allowing for easy disassembly, quick installation, factory manufacturing, and a short assembly time upon delivery to the site.

Four: Structural Features

Overall modular assembly, capable of repeated disassembly and reassembly.

2. Wall panels in the audiometric booth are constructed with standard 0.9mm perforated acoustic aluminum tiles

3. The exterior walls of the audiometric chamber are lined with 1.2T galvanized cold-rolled steel plates labeled as standard.

4. Acoustic wall sandwich material selection: fire-resistant, eco-friendly sound-absorbing cotton

5. Listening room walls are constructed with 16mm high-density damping panels

6. Exterior steel plate with baked paint finish, maintaining color without chipping for over 10 years

7. The listening room is constructed with a composite structure and features soundproof walls. It is installed in a suspended manner, offering all-weather anti-interference capabilities against external noise and vibrations.

8. Acoustic and soundproofing walls and doors are made of steel plate, featuring a sturdy structure, good rigidity, and an anti-shear deformation structural design, with flexible door opening.

9. The audiometric room is externally smooth and aesthetically pleasing, featuring wall coatings that are easy to clean.

Five: Acoustic Indices of the Audiometric Booth

At an ambient noise level of 55 decibels with no abnormal disturbances such as ground pounding, pile driving, impacts, or specific low-frequency noise, the indoor background noise level. Listening room, acoustic field listening room ≤ 25 dB(A), medical room ≤ 25 dB(A).

Six: Soundproofing Room Wall Design

The soundproofing room walls include but are not limited to the following materials: 16mm damping density board - 1.2mm galvanized cold steel plate - 0.9mm metal micro-perforated sound-absorbing aluminum clip - sealing materials - sound-absorbing carpet

2. Wall thickness of the audiometric booth is determined according to the drawings.

3. Floating Floors: To prevent external noise from the listening room's surroundings from entering the sensitive area, the entire listening room is suspended, achieving the required quietness and vibration stability for the testing environment.

4. Soundproof Door: Net door size 1900*800, featuring a steel magnetic silent door, single-leaf rotating style

Seven: Ventilation and Air Exchange (Noise Reduction Channels)

The soundproofing room utilizes exhaust fans combined with specialized acoustic channels for ventilation. The noise level is 35 dB. Acoustic channels are devices that allow air flow while preventing or reducing sound transmission, serving as a crucial measure for eliminating aerodynamic noise. Fixing sound-absorbing materials to the inner walls of the air flow channels or arranging them in a certain pattern within the pipes constitutes an acoustic channel.

8: Electrical System Noise Control

The room is equipped with LED lighting to ensure optimal indoor illumination. To maintain a low-noise environment within the room, careful attention must be given to the selection of noiseless lighting fixtures and equipment during design.
