Embodiment 1

[0018] Such as figure 1 As shown, the headgear audiometry device of this embodiment includes a housing 1 and earmuffs 2 . A sound-insulating layer 4 is provided between the earmuff 2 and the shell 1 . The sound insulation layer 4 has multiple layers and is filled with sound insulation materials. Sealing elements 5 are fixedly installed on the outer edges of the earmuffs 2 and the shell 1 . The sealing member 5 is an air bag, which has a better sound insulation effect than rubber seals or sponge seals. The shell 1 covers the area around the ears of the subject. When the subject wears the head-cover audiometry device, the sealing member 5 is in close contact with the subject's head, effectively isolating external noises and forming a quiet space around the subject's ears.

[0019] The shell 1 and the earmuffs 2 are two groups, which are respectively worn on the left and right sides of the subject during the hearing test, so as to perform hearing test on both ears of the subj...

Embodiment 2

[0023] Such as figure 2 As shown, the headgear audiometry device of this embodiment is basically the same as that of Embodiment 1, except that it also includes a mobile device 7 and a control device. The control device controls the mobile device 7 , which is connected to the housing 1 .

[0024] The moving device 7 includes a motor 71 , a screw rod 72 , a slide plate 73 and a slide rail 74 . The motor 71 is connected to the screw rod 72 through a shaft coupling. The slide plate 73 and the slide rail 74 are slidingly fitted. The slide plate 73 is installed on the screw mandrel 72 . The housing 1 is fixedly connected to the slide plate 73 through a bracket. Therefore, the motor 71 can drive the sliding plate 73 to move, and then drive the housing 1 to move.

[0025] The motor 71 is connected with the control device, and the control device is also connected with a pressure sensor. The position of the pressure sensor corresponds to the sealing member 5, and when the sealing...

Embodiment 3

[0028] Such as image 3 As shown, the headgear-type audiometry device of this embodiment is basically the same as that of Embodiment 1, except that the shell 1 is fixedly connected with a mask 6 . When the two sets of shells 1 and earmuffs 2 are attached to the subject's head by pressure, the masks 6 on the two sets of shells 1 are closed.

Abstract

The invention discloses a hood-type audiometric device. The device comprises a shell and earshields, wherein the earshields are connected with sound production devices; a sound isolation layer is arranged between each earshield and the shell; a seal part is arranged on the outer edge of each earshield and the shell. According to the device, external noise can be effectively isolated since the sound isolation layer is arranged between the shell and each earshield and seal parts are the outer edge of the shell and each earshield, a silence space is formed for the ears of a detected person to ensure normal performance of listening tests. The hood type audiometric device can be used for carrying out listening tests as long as the device is worn on the head of the detected person during testing and does not need to be used in a sound isolation room, is convenient to carry, and has wide application.

Description

technical field [0001] The invention relates to hearing detection equipment, in particular to a hood-type audiometry device. Background technique [0002] The hearing test needs to be carried out in a relatively quiet environment, generally using a soundproof room. Hearing tests were performed directly wearing audiometric headphones in a soundproof room. However, the soundproof room usually adopts a cement structure or a plate structure, and installs soundproof doors and windows. Due to the requirements of the test environment, the listening test can only be performed at a fixed location. It is very inconvenient when some special groups of people need to detect hearing. Contents of the invention [0003] The object of the present invention is to provide a headgear audiometry device which can solve at least one of the above-mentioned problems. [0004] In order to achieve the above object, according to one aspect of the present invention, a headgear-type audiometry devi...
