Description

Technical Field

[0001] The utility model belongs to the field of hearing test equipment, in particular to a mobile audiometry room. Background Art

[0002] At present, hearing tests for hearing patients are conducted by having the patients sit in a closed room and wear headphones. The hearing doctor sends pure tone commands through the headphones, and the patients respond after hearing the sounds. The sizes of the sounds emitted by different frequencies are marked on a graph and the average is calculated, which is the patient's hearing condition. To connect a conventional soundproof room to an audiometer, a hole needs to be opened in the wall to extend the headphone wire into the soundproof room, which will cause external sounds to enter through the hole, resulting in the soundproof room not achieving good sound insulation.

[0003] During the test, the human body suddenly enters a silent, vacuum-like environment, causing brief discomfort, which results in the inability to respond to some subtle test sounds in the first place, affecting the results of the hearing test.

[0004] A hearing test soundproof room (patent application number: CN202321972735.1) is disclosed, comprising a soundproof room body (1), the soundproof room body (1) comprising an upper panel (101), a bottom panel (102), a left partition (103) and a right partition (104), a soundproof door (2) and a soundproof window (3) are provided on the right partition (104), a bracket (4) for placing headphones is provided on the inner side of the soundproof window (3), a through hole (401) is provided on the bracket (4), a power strip (5) is installed on the right partition (104) below the soundproof window (3), the headphone cable passes through the through hole (401), and the power strip (5) is connected to the audiometer.

[0005] This public solution improves the sound insulation effect to a certain extent. However, in order to connect the headphone cable inside the soundproof room with the power strip outside, it is still necessary to open a hole in the wall of the soundproof room, which will still cause the introduction of external sounds and cannot achieve the optimal sound insulation effect. In addition, the soundproof room cannot adapt to the human body to a silent environment. Utility Model Content
