The audiometric rooms typically include: Electro-audiometric rooms - Pure Tone Audiometric Rooms, Sound Field Audiometric Rooms, and Behavioral Audiometric Rooms, among others. Essentially, audiometric rooms are medical facilities designed to provide a relatively quiet environment for audiologists to conduct hearing tests. Generally, the background noise within an audiometric room should not exceed 30dB(A). The requirements may vary slightly depending on the testing method, such as higher background noise requirements for sound field testing and the necessity to place patients in a quiet environment for frequency-specific hearing threshold measurements during electro-audiometric testing. Therefore, based on the different testing methods, audiometric rooms used in clinical settings within the medical field are respectively called Electro-audiometric Rooms (Pure Tone Audiometric Rooms), Sound Field Audiometric Rooms, and Behavioral Audiometric Rooms, etc. Other types of audiometric rooms usually include those for physical examinations, known as Physical Examination Audiometric Rooms, due to their use in occupational health system physical examinations. There are also mobile audiometric rooms installed on examination vehicles, which are also referred to as Vehicle Audiometric Rooms. Despite different names, they essentially serve the same purpose, which is to ensure the soundproofing effectiveness meets the requirements for hearing tests. Mobile audiometric rooms are used for on-site hearing tests and physical examinations, providing convenient and quick services for both patients and healthcare professionals.
