What do the balance cover and atmosphere cover of deafness mean?

The atmosphere set is a set with more bass, and the equalization set is a set with more balanced sound quality. Hearing loss is a jargon of hosting industry. The host wears headphones on his ears when hosting a performance, and the director can guide the host to arrange the program through headphones. Auricular gyrus can be divided into ambience set auricle and equilibrium set auricle according to different sound quality, in which ambience set auricle is a set with more bass and equilibrium set is a set with more balanced sound quality. The director will not easily use ear feedback when recording a program, which will interfere with the host's thinking, and the wonderful degree of the host's program depends largely on the host.
