A remote control hearing protection system in high decibel noise environment

Abstract

Aiming at the working environment with multiple frequencies and strong noise, the present invention adopts a wireless transmitting device to send a remote control signal to centrally control several hearing protection devices; after receiving the remote control signal, the hearing protection device controls the actuator to complete the blocking action and implement hearing protection; in addition, the hearing protection The device is equipped with a control unit with delay control, which delays from receiving the remote control signal to pressing the tragus for 3-5 seconds before the strong noise comes, blocks the ear canal, blocks the noise, and implements hearing protection; in addition, the hearing protection device There is also a sound receiving control channel, through the analysis and processing of the noise signal, the blockage will be released automatically after the strong noise is over, and the natural hearing will be restored, so as to realize "protection when there is strong noise and release when there is no strong noise" to effectively relieve the long-term on-site staff The discomfort of wearing earplugs and earmuffs for hours.

Description

technical field [0001] The invention relates to the technical field of hearing protection, in particular to a remote control hearing protection system in a high-decibel noise environment. Background technique [0002] In the multi-frequency, strong noise working environment, such as blasting, mountain blasting, artillery firing and other blasting sites, or rocket engine ignition test sites with frequent detonations, artillery test sites and other environments, the traditional hearing protection technology is to use sign language and semaphore Or broadcasting and other forms, instructing or expressly instructing on-site staff to wear earplugs or earmuffs to effectively block or weaken the high-decibel noise from the outside, so as to protect the hearing of workers. After the blasting is over, the command system releases the safety protection order according to the situation, and the work site returns to normal order. [0003] This traditional hearing protection technology ma...

Problems solved by technology

[0004] 1. Long wearing time: Wearing earplugs or earmuffs for a long time will cause extreme discomfort to the workers, and more seriously, it will make the air pressure inside and outside the eardrum in the ear cavity unbalanced, which is very likely to cause dull hearing or deafness in both ears , long-term wearing is prone to hearing occupational diseases, seriously affecting the physical and mental health of staff

[0005] 2. There are loopholes in on-site defense protection: using sign language, semaphore or broadcasting to command, there are inevitably dead ends in management, which will cause accidental hearing damage to staff who do not wear earplugs or earmuffs in time on site

[0006] 3. It is not easy to improve work efficiency: frequent removal, wearing earplugs or ear protection with both hands will stop manual operations on site and reduce work efficiency. At the same time, workers cannot communicate with each other when wearing them for a long time. Psychological barriers and safety hazards
