技术领域technical field
本发明属于一种听力装置，尤其是涉及一种支架式隔音测听装置。The invention belongs to a hearing device, in particular to a bracket type sound-proof audiometry device.
背景技术Background technique
大部分听力学测试都要求在隔音的环境中进行，这样可以避免在测试过程中其它声源干扰到刺激声导致结果不准，目前常规的隔音装置主要为隔音室。隔音室是主要采用钢材、隔音材料和吸引材料搭建而成的密闭房间，通常占地面积较大，内尺寸最低要求1.0×1.0×2.0㎡，造价成本较高，而且存在一个大问题，就是在隔音室内，由于空间小，在里面发出的任何响声，例如衣服摩擦的沙沙声，吞咽口水的声音等都会变得相当明显，这就可能让受试者在测试过程中不能较好地放松下来，需要避免姿势的转换，呼吸及口水吞咽等问题。所以说隔音室虽然对其外部的声源较好地阻隔，但对内部发出响声则无作用。Most audiology tests are required to be carried out in a sound-proof environment, so as to prevent other sound sources from interfering with the stimulating sound during the test, resulting in inaccurate results. At present, the conventional sound-proof devices are mainly sound-proof rooms. The soundproof room is an airtight room mainly made of steel, soundproof materials and attractive materials. It usually covers a large area and requires a minimum internal size of 1.0×1.0×2.0㎡. The cost is relatively high, and there is a big problem, that is, in In the soundproof room, due to the small space, any noises in it, such as the rustling of clothes rubbing, the sound of swallowing saliva, etc. will become quite obvious, which may prevent the subjects from relaxing well during the test. Changes in posture, breathing and swallowing of saliva need to be avoided. Therefore, although the soundproof room can better block the external sound source, it has no effect on the internal sound.
