Bracket type soundproof audiometry device

Abstract

The invention discloses a bracket type soundproof audiometry device. The bracket type soundproof audiometry device comprises a bracket and headphones, wherein the bracket comprises a horizontal rod and a vertical rod; the horizontal rod is connected with the upper part of the vertical rod; the headphones are arranged on the horizontal rod and are pressure type airbag headphones; the vertical rod can vertically stretch; the horizontal rod can horizontally stretch. The headphones are arranged on the horizontal rod and the vertical rod which can be stretched, so the positions of the headphones are conveniently adjusted in the audiometry process according to the height of a user, and convenience in use is realized; meanwhile, the headphones are pressure type airbag headphones, so that the sealing property is adjusted by air pressure when the headphone are used and a soundproof effect is realized; audiometry is not needed to be performed in a soundproof room, so that the space is greatly saved; in addition, the influence of sound transmitted by audiometry on the audiometry result is avoided, and the audiometry precision is improved.

Description

technical field [0001] The invention belongs to a hearing device, in particular to a bracket type sound-proof audiometry device. Background technique [0002] 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 sw...

AI Technical Summary

Problems solved by technology

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 the soundproof room, due to the small space, any noises made inside, such as the rustling of clothes rubbing against each other, the sound of swallowing saliva, etc. will become quite obvious, which may prevent the subjects from relaxing well during the test. Need to avoid posture change, breathing and saliva swallowing and other problems

Therefore, although the soundproof room can better block the external sound source, it has no effect on the internal sound.
