The audiometric room typically includes: electrical audiometric rooms - pure tone audiometric rooms, sound field audiometric rooms, and behavioral audiometric rooms, among others. Essentially, an audiometric room is a medical audiometric room, simply put, it is primarily constructed to provide a relatively quiet environment for otolaryngologists to conduct hearing tests. Generally, the background noise in the audiometric room should not exceed 30dB(A). The requirements may vary slightly depending on the testing method, such as when conducting sound field tests, where the background noise requirements for the audiometric room are higher. During electrical audiometry, it is necessary to place the patient in a quiet environment to measure the thresholds of different frequencies. Therefore, based on the different testing methods, the audiometric rooms used in the medical field for clinical use are respectively called electrical audiometric rooms - pure tone audiometric rooms, sound field audiometric rooms, and behavioral audiometric rooms, etc.
