Soundproof Room Construction Cost - Quotation - Project - Company [Beijing Zhongke Xunda Technology Development Co., Ltd.] The basic components of a soundproof room include: electrical soundproof room - pure tone soundproof room, sound field soundproof room, and behavioral soundproof room, among others. In essence, a soundproof room is a medical soundproof room, simply put, it is designed to provide a relatively quiet environment for audiologists to conduct hearing tests. Typically, the background noise inside a soundproof 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 soundproof room are higher. During electrical hearing tests, it is necessary to place the patient in a quiet environment to measure different frequencies of hearing thresholds, etc. Therefore, based on the different testing methods, soundproof rooms used in the medical field for clinical use are respectively called electrical soundproof rooms - pure tone soundproof rooms, sound field soundproof rooms, and behavioral soundproof rooms, etc.
