Aviation headphones are used in airplanes, cars, subways, etc., to facilitate passengers to listen to audio and watch videos to enjoy a pleasant journey.
The aviation earphones are mostly disposable, so the structure is extremely simple, the shape is relatively ordinary, the materials are small, and the annual usage is very large. The number of inquiry can reach several million or even tens of millions, so the cost is very cheap. earphones can cost as little as 10-15 cents. Therefore, they are disposed of as garbage after used, and passengers could take it away for personal use.
Styles can be divided into on ear headphones and in ear earphones.
Functional difference: power, impedance, and sensitivity etc. are also different. Airplane Headphone is mainly customized according to the equipment, place and user used. For example, 1 customer might require 300 ohms impedances , and other customers may need 32 ohms. For adults, the sensitivity may reach 100DB or more.To children, the sensitivity may be around 85-90 DB.
In addition, aviation headphones are not all disposable ones. Some first-class cabins need to be equipped with headphones with good noise reduction, sound quality and functions. So the price will be much more expensive.

Since 2011, Zhang Yong (Deputy Director of the Department of Transportation Inspection of Shanghai Jiading Power Supply Company) has proposed the "4S" model of safety management with "safety education, security risk assessment, security system, and security pre-control" as the main contents, and strives to create a standardization. Safety management route. In December 2012, Jiading Power Supply Company formally promoted the “4S†model of safety management, introduced this new model into safety production processes and standardized management, ensuring stable operation of the power grid.
Pay close attention to safety education and stress risk assessment
In light of the lack of security awareness and the lack of specific security education within the company, Zhang Yong decided to take actions to eliminate safety workflows based on extensive research.
"Safety first, prevention is the main thing." Zhang Yong often put this sentence in his mouth. He clearly realized that safety education is the first line of defense to identify danger points and formulate preventive measures. He said: "In the face of the new requirements for the development of smart grids, only by building a scientific safety education system can we introduce safe production to the lean management path." Therefore, after a scrutiny of research, an analysis of typical event cases is the main line." The Ankang Cup "safety knowledge contest" as the carrier's distinctive safety education system came into being.
From 2010 to 2011, after conducting job safety education and training and accumulating preliminary experience, Zhang Yong began to explore safe production training methods combined with practical training, promoted safety technology grade certification system, and strengthened rules and regulations and safety skills training. “The pilot project of Jiading Power Supply Company's safety education work is full of new ideas and closely integrates with the safety production practice of this unit. This is a bold attempt in safety education work and has achieved very good results.†Head of the Inspection Department of Shanghai Electric Power Company Indicated.
The key to preventing security incidents is to be aware of security risks. From proposing concepts and formulating norms to continuous improvement in the later period, Zhang Yong devoted a lot of effort to this management model. He always confidently introduced: "This security management model carries out risk identification from various aspects such as personnel quality, on-site management, equipment and protection, production environment, and comprehensive production safety management, and in-depth search for various unsafe factors that affect safety. Achieved all-round, all-round, and full-process management and control of safety production."
After Zhang Yong introduced the management method, Jiading Power Supply Company carried out risk assessments for the team and extended the focus from the past to the work team leader for all members of the team. At the same time, according to the different team members to develop differentiated security risk assessment measures, so that everyone has a clear account in mind.
Implement safety systems and implement safety pre-control
In view of the characteristics of Jiading Power Supply Company, Zhang Yong set up an innovative system in the scope of the Ministry of Inspection and Quarantine to link the management personnel with the production team system, on-site production supervision and on-site supervision system, on-site safety inspection system and other two systems.
“Since the implementation of the new system, full-time meetings with our class have often been transferred to classes to assist me in the safety management of the team,†said Dongxing Dong, head of the protection automation group.
Zhang Yong said that the implementation of these three systems has optimized the processes, improved the efficiency, improved the safety standard system, and strengthened the on-site safety level control and supervisory supervision.
After the implementation of the new system in the Ministry of Transportation Inspection, it responded well. In the next step, the system will be gradually extended to various teams of Jiading Power Supply Company.
In the past, safety management and pre-control measures were mostly set up by departments, and there was a lack of communication with first-line teams, resulting in faults at the management level and at the production level, as well as the accuracy of safety management and the impossibility of pre-control measures. With the promotion of the "4S" model, front-line teams have also participated in the formulation of safety pre-control measures, making safety management more accurate and pre-control measures more real.
Zhang Yong said that safety management pre-control work is mainly performed in two layers. The Ministry of Transportation Inspection mainly implements the work points issued by the Jiading Power Supply Company, and guides and urges front-line personnel to implement on-site safety measures in response to potential hazards in the next week. The team is the key to implementing pre-control measures for security risks. The new pre-control measures for operational safety risks require the team to discuss the operating plan in advance when receiving instructions from the superior department for hazard sources, analyze the construction environment, tools and construction measures and work out daily The dangerous points and pre-control measures of the work are sent to the person in charge of the department for summary and review to ensure that the pre-control of operational safety risks is implemented.
“The current pre-control process has become more complex than before, and the workload has increased accordingly. However, young people in the class have applauded. They all said that they are now in substations and there are dangerous distressed snacks.†The team leader Wang Rixue said.
In recent years, with the promotion of Zhang Yong, a security management revolution triggered by the “4S†model is releasing its strength. Zhang Yong always said: "Safety management is a long-term project. In the future, I will continue to improve the "4S" model."
