Typically, the background noise in a listening 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 during electrical hearing tests, patients must be placed in a quiet environment to measure thresholds at different frequencies. Therefore, based on different testing methods, listening rooms used in the medical field for clinical use are respectively called electrical listening rooms - pure tone listening rooms, sound field listening rooms, and behavioral listening rooms, etc.
