Problems solved by technology

The soundproof room can only block the external noise, but it cannot effectively eliminate the reverberation noise and the low-frequency noise generated by the vibration in the room (the sound pressure level is about 40dB), which will cause a large degree of interference to the acquisition of the acoustic signal
At present, laryngoscopes commonly used in China include fiberoptic laryngoscopes, electronic endoscopes and strobe laryngoscopes, which are used to observe the physical form of vocal cord vibrations, but these laryngoscopes have the disadvantages of low resolution and the inability to measure vocal cord vibrations in real time
In addition, the existing voice pathological treatment is based on the assessment of the human voice, but many voice diseases cannot be observed and studied on the human body, so there are also great limitations in the pathological research objects

Abstract

The invention provides an anti-interference throat vibration sound production assessment device and relates to a voice assessment device. The anti-interference throat vibration sound production assessment device is provided with a silence room and an indoor assessment device. The silence room is provided with a silence room body, a silencing ventilation device and a safety alarm device. A sound insulation door is arranged on an entrance of the silence room body, the silencing ventilation device is provided with a silencing ventilation box, the safety alarm device is provided with a safety alarm, and the indoor assessment device is provided with a throat experiment operation unit and a data acquisition unit. The throat experiment operation unit is provided with an off-body throat experiment platform and an instrument fixing platform .The off-body throat experiment platform is provided with an artificial lung, an air compressor and an off-body throat fine-adjustment fixing platform. The instrument fixing platform is provided with a cold light source, a two-dimensional stepping motor, a stepping motor controller and an optical platform support. The data acquisition unit is provided with a digital electronic pressure gauge, a digital electronic aerometer, a digital electronic phonometer, an electret capacitor microphone, a sound card, a photographic instrument and a computer. By the adoption of the assessment device, the limitation of clinical medicine voice assessment can be effectively eliminated and data accuracy and data reliability can be improved.

Description

technical field [0001] The invention relates to a voice evaluation device, in particular to an anti-interference laryngeal vibration evaluation device. Background technique [0002] At present, domestic voice evaluation is limited to the use of a combination of microphones, aerodynamic devices, and laryngoscopes in hospital soundproof rooms. The soundproof room can only block the external noise, but it cannot effectively eliminate the reverberation noise and the low-frequency noise generated by the vibration in the room (the sound pressure level is about 40dB), which will cause a large degree of interference to the acquisition of the acoustic signal. At present, laryngoscopes commonly used in China include fiberoptic laryngoscopes, electronic endoscopes and strobe laryngoscopes, which are used to observe the physical form of vocal cord vibrations. However, these laryngoscopes have the disadvantages of low resolution and the inability to dynamically measure vocal cord vibrati...
